Perkins (2-6) took the loss Monday, allowing two runs on a hit and three walks over 5.2 innings against the Red Sox. He struck out four.
The right-hander didn't allow a run while on the mound, but after departing with two runners aboard and two outs in the sixth inning, Jose Suarez surrendered a grand slam to Ceddanne Rafaela that saddled Perkins with the loss. Monday's performance was encouraging, though it's been a challenging season for the 26-year-old, who opened the campaign in a relief role before shifting into the starting rotation in June. He owns a 6.45 ERA, 1.36 WHIP and 80:27 K:BB across 68.1 innings over 26 appearances (eight starts). Perkins is next lined up to pitch Saturday against the Tigers.

Athletics' Jack Perkins: Settles in after early homer
Rotowire
Perkins allowed three runs on five hits and a walk while striking out four over five innings in a no-decision versus the Diamondbacks on Tuesday.
Perkins gave up a three-run home run to Max Kepler in the first inning. After that Perkins settled in for a decent start, though the Athletics didn't catch up until the ninth inning. This was his longest outing in July -- he's allowed 13 runs over 11.2 innings in three appearances this month. Overall, Perkins has a 6.75 ERA, 1.42 WHIP and 76:24 K:BB through 62.2 innings across 25 games (seven starts). He's tentatively projected for a home start versus the Red Sox early next week.

Athletics' Jack Perkins: Struggles in bulk relief
Rotowire
Perkins (2-5) took the loss Thursday against the Tigers, allowing three runs on two hits and two walks while striking out two over three innings.
The right-hander entered behind opener Jose Suarez, who recorded four outs without a baserunner. Perkins was hurt by the long ball, surrendering a solo homer to Jake Rogers to open the scoring before Zach McKinstry added a two-run blast later in the outing. Across seven starts and bulk-relief appearances this year, Perkins has struggled to an 8.19 ERA with zero wins.

Athletics' Jack Perkins: Fades late in no-decision
Rotowire
Perkins allowed three runs on six hits and two walks while striking out six batters over five-plus innings in a no-decision against Pittsburgh on Tuesday.
The A's staked Perkins to a 4-0 lead in the first inning, and he limited the Pirates to just one run through five frames. However, the right-hander began the sixth by serving up a solo homer to Bryan Reynolds followed by a Ryan O'Hearn double before being pulled. O'Hearn eventually came around to score, and a late Pittsburgh comeback removed Perkins from factoring into the decision. The plus side is that Perkins completed five frames for the first time this season, and he reached 85 pitches for the second straight start. It hasn't been the smoothest of transitions for Perkins after he worked out of the bullpen until the beginning of June, but Tuesday's outing was at least a step in the right direction.

Athletics' Jack Perkins: Goes four innings again
Rotowire
Perkins allowed three runs on five hits and three walks while striking out four over four innings in a no-decision versus the Brewers on Wednesday.
Perkins was a little better this time out, but he still wasn't very efficient in his second start of the year. He threw 56 of 89 pitches for strikes and allowed two home runs while pitching at hitter-friendly Las Vegas Ballpark. In his two starts, he's allowed eight runs on 10 hits and five walks while striking out 10 over eight innings. Combined with his work out of the bullpen this season, Perkins has a 6.25 ERA, 1.36 WHIP and 43:12 K:BB through 36 innings over 19 appearances. If the Athletics still need his help in the rotation, Perkins would be tentatively lined up for a home start in Sacramento against the Pirates next week.

Athletics' Jack Perkins: Handed another start
Rotowire
Perkins is slated to start Wednesday's game against the Brewers in Las Vegas.
Perkins made his first 17 appearances of the season out of the bullpen before the Athletics elected to slide him into the rotation last week in the wake of Aaron Civale (shoulder) and Luis Severino (shoulder) both landing on the injured list within a few days. The right-handed Perkins was handed a limited workload in his first start Friday, tossing 75 pitches and four innings while striking out six batters and yielding five earned runs on five hits and two walks. While Perkins should have the opportunity to build up his pitch count in Wednesday's outing, he'll carry plenty of risk as a streaming option while pitching in an even more hitter-friendly venue (Las Vegas Ballpark) than the Athletics' usual home park in Sacramento (Sutter Health Park). The Brewers and Athletics combined for 29 runs and 11 home runs -- both MLB single-game season highs -- over 12 innings during Monday's series opener.

Athletics' Jack Perkins: Returning to rotation
Rotowire
Perkins will rejoin the Athletics' rotation and start Friday's game against the Astros, Martin Gallegos of MLB.com reports.
With Aaron Civale (shoulder) and Luis Severino (shoulder) both set to spend several more weeks on the injured list, the A's will move Perkins out of the bullpen to fill the open spot in the rotation. The 26-year-old has been operating as a long reliever all season, posting a 5.46 ERA and 1.21 WHIP over 28 innings. He has just four appearances this season of more than two innings, but he worked up to 4.2 frames against the Mariners last week.

Athletics' Jack Perkins: Settles for first hold Friday
Rotowire
Perkins recorded his first hold of the season in Friday's 4-3 win over the Orioles, giving up one run on one hit and one walk over two-thirds of an inning. He struck out two.
Entering the game in the ninth inning to protect a 4-2 lead, Perkins couldn't get the job done, tossing just 13 of 25 pitches for strikes and getting the hook with the tying run aboard. Hogan Harris picked up the final out to get the save. Perkins is the preferred closing option for A's manager Mark Kotsay, but the 26-year-old righty is still in his probationary period and has been scored upon in back-to-back appearances. On the season, Perkins sports a 4.11 ERA, 1.24 WHIP and 21:5 K:BB through 15.1 innings while converting three of four save chances.

Athletics' Jack Perkins: Saddled with first loss, blown save
Rotowire
Perkins (2-1) was charged with the loss and a blown save Wednesday against the Phillies, allowing four runs (two earned) on two hits and one walk in 1.1 innings. He struck out two.
Perkins, who has been emerging as the Athletics' primary closer as of late, entered in the seventh inning Wednesday. The right-hander tossed a clean seventh before unraveling in the eighth, recording just one more out. A throwing error by Jeff McNeil prevented two of the runs from being earned, but nonetheless Wednesday's usage shows that roles remain fluid in the bullpen. Through 14.2 innings, he has a 3.68 ERA, 1.16 WHIP and 19:4 K:BB while converting three of his four save chances.

Athletics' Jack Perkins: Earns win in relief
Rotowire
Perkins (1-0) earned the win Friday against the Mets after tossing 2.1 scoreless innings out of the bullpen. He allowed three hits while striking out three.
This was Perkins's first appearance of the season at the big-league level after he was recalled from Triple-A Las Vegas on Thursday. Perkins did a good job of finding the plate, as he tossed 22 of his 30 pitches for strikes. He should remain part of the A's bullpen, but he won't have a lot of fantasy appeal as long as he stays out of a high-leverage role.

Athletics' Jack Perkins: Summoned from minors
Rotowire
The Athletics recalled Perkins from Triple-A Las Vegas on Thursday.
Perkins has been operating as a multi-inning reliever at Las Vegas, allowing four runs with a 9:7 K:BB over 7.2 innings. The Athletics need a fifth starter after sending down Luis Morales earlier this week, and Perkins has plenty of past experience in the rotation. However, the righty's usage this season suggests it's more likely he'll provide length in the bullpen.

Athletics' Jack Perkins: Falls short of roster spot
Rotowire
The Athletics optioned Perkins to Triple-A Sacramento on Monday, Martin Gallegos of MLB.com reports.
Perkins came to camp in the mix for a spot either in the rotation or bullpen, but he didn't win either after allowing four runs with a 7:7 K:BB over nine Cactus League frames. The 26-year-old remains one of the club's more talented arms and should play a role with the big club in 2026. Perkins will likely open the season in the Sacramento rotation.

Athletics' Jack Perkins: Role undetermined
Rotowire
Athletics manager Mark Kotsay said last week that Perkins (shoulder) will enter camp as a starting pitcher, but the team has yet to decide whether he'll be a starter or reliever in 2026, Martin Gallegos of MLB.com reports.
"He's a weapon that we have yet to determine the path," Kotsay said. Perkins was much more effective as a reliever (2.75 ERA, 24.7 percent strikeout rate) than as a starter (5.68 ERA, 21.4 percent strikeout rate) during his time with the Athletics last season, but the 26-year-old is one of the A's better young arms so the team doesn't want to relegate him to a relief role just yet. The right-handed Perkins ended last season on the injured list with a right shoulder strain, and it's not clear if he has any restrictions at the start of camp.

Athletics' Jack Perkins: No timetable for return
Rotowire
Perkins (shoulder) received a subacromial injection Monday and is without a timetable for a return, Martin Gallegos of MLB.com reports.
Perkins was placed on the 15-day injured list Friday due to a strained right shoulder, and the club is still uncertain as to how much time he'll miss. Whether he's able to pitch again this season should become more apparent when/if he's cleared to begin a throwing program. Osvaldo Bido is expected to replace Perkins in the rotation in Tuesday's game against the Tigers.

Athletics' Jack Perkins: Placed on IL
Rotowire
The Athletics placed Perkins on the 15-day injured list Friday with a strained right shoulder.
Perkins appears to have picked up the injury during Thursday's start against Minnesota, when he yielded two runs over five innings en route to his third win of the campaign. The 25-year-old has a 4.19 ERA in 38.2 innings with the A's this season. Joey Estes was recalled from Triple-A Las Vegas to fill Perkins' spot on the roster and presumably in the rotation.

Athletics' Jack Perkins: Strikes out seven in win
Rotowire
Perkins (2-2) allowed three runs on five hits and three walks while striking out seven over five innings to earn the win over the Angels on Friday.
Perkins gave up a two-run home run to Zach Neto in the fifth inning, but the Athletics were able to maintain the lead before turning the game over to the bullpen. This was a fine performance for Perkins, who has now won his last two starts. He has surrendered 10 runs over 14 innings while posting a 16:7 K:BB as a starter after finding success as a multi-inning reliever to begin his big-league career. Overall, he has a passable 4.28 ERA, 1.13 WHIP and 35:14 K:BB through 33.2 innings across 11 appearances. Perkins' next start is projected to be on the road versus the Twins.

Athletics' Jack Perkins: Handed another start
Rotowire
Perkins is slated to start Saturday's game against the Orioles at Camden Yards.
Perkins posted a 2.75 ERA while working as a reliever in his first eight MLB appearances, before being moved into the rotation this past weekend. In his first career start Sunday, the young righty struck out four over three innings but was tagged for four earned runs on five hits and three walks. The Athletics intend to develop him as a starter, so Perkins should have an extended runway in the rotation even after his inauspicious first start. Perkins tossed a season-high 62 pitches in that loss to the Diamondbacks, so he may have some kind of workload restriction in place for his second start.

Athletics' Jack Perkins: Struggles in first career start
Rotowire
Perkins (0-2) took the loss against the Diamondbacks on Sunday, allowing four runs on five hits and three walks while striking out four over three innings.
Making the first start of his career after debuting in a long-relief role, Perkins labored through three frames and needed a season-high 62 pitches to get nine outs. The 25-year-old righty had been effective out of the bullpen, carrying a 2.75 ERA, 0.92 WHIP and 19:7 K:BB over 19.2 innings entering Sunday. While the transition to the rotation didn't yield immediate success, Perkins should have a fairly long leash as the A's give the top prospect a chance to establish himself as a long-term rotation piece.

Athletics' Jack Perkins: Receives first MLB call-up

The Athletics selected Perkins' contract from Triple-A Las Vegas on Sunday.
The right-hander has been working as a starter with Las Vegas and has posted a 2.86 ERA, 1.02 WHIP and 68:20 K:BB across 44 innings this season, though he may be ticketed for a relief role to begin his time in the big leagues with the Athletics having already announced starters for their next four games. According to Martin Gallegos of MLB.com, manager Mark Kotsay said Perkins will be available in relief Sunday against Cleveland, though the skipper didn't specify whether the 25-year-old will stick in that role going forward.

Athletics' Jack Perkins: Makes season debut
Rotowire
Perkins (undisclosed) struck out four and allowed three hits and no walks over four scoreless innings Thursday for Triple-A Las Vegas after being reinstated from the 7-day injured list.
Perkins missed the first month of the season due to an unspecified injury, but he debuted in impressive fashion Thursday. Regarded as one of the Athletics' top pitching prospects, Perkins could be a candidate to join the big-league rotation later on this summer.
