Athletics' Jack Perkins: Placed on IL
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: Grabs third straight win
Perkins (3-2) earned the win Thursday over the Twins, allowing two runs on three hits and four walks over five innings. He struck out two.
Perkins, who joined the A's rotation earlier this month, has won his last three starts while posting a 4.50 ERA with 14 strikeouts in that span (16 innings). Overall, the rookie right-hander sports a 4.19 ERA with a 1.16 WHIP and 37:18 K:BB across 38.2 innings this season. Perkins is currently lined up for a tough home matchup with the Tigers in his next outing.

Athletics' Jack Perkins: Strikes out seven in win
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: Earns first win Saturday
Perkins (1-2) earned the win against the Orioles on Saturday, allowing one run on three hits and one walk with five strikeouts over six innings.
Perkins allowed a three-run homer in the first inning but rebounded with five scoreless frames to earn his first career win. The 25-year-old also logged his first major-league quality start, bouncing back after surrendering four runs over three innings in his rotation debut Sunday. He'll carry a 4.08 ERA, 1.05 WHIP and 28:11 K:BB across 28.2 innings into a home matchup with the Angels next weekend.

Athletics' Jack Perkins: Handed another start
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
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: Getting shot in rotation
Perkins is moving into the Athletics rotation and will start Sunday versus Arizona, Martin Gallegos of MLB.com reports.
When Mason Miller was traded to San Diego on Thursday, Perkins looked to be next in line to move into the closer role. Instead, the rookie right-hander will get a look in the rotation, and his start Sunday doesn't appear to be a one-off arrangement. Perkins has pitched well for the Athletics, posting a 2.75 ERA, 0.92 WHIP and 19:7 K:BB over 19.2 innings spanning eight appearances, but he hasn't gone more than 3.1 innings or 54 pitches in any outing. That said, he had handled a full-time starting role for Triple-A Las Vegas prior to being promoted June 22, logging a 2.86 ERA while striking out 68 over 44 innings. Perkins will likely be on some sort of a pitch count Sunday, though he may need only two or three outings to get stretched out enough to handle a typical starter's workload.

Athletics' Jack Perkins: Secures two-inning save
Perkins allowed one run on one hit with no walks or strikeouts over two innings to notch a save against the Mariners on Wednesday.
Perkins entered in the eighth inning and retired the side in order in that frame. He served up a solo homer to Randy Arozarena in the ninth but didn't give up any additional hits and finished off the win to record his third save. Perkins has been quite effective for the A's since making his big-league debut June 22, posting a 2.75 ERA, 0.92 WHIP and 19:7 K:BB over 19.2 innings spanning eight appearances. Interestingly, manager Mark Kotsay said after Wednesday's contest that closer Mason Miller was unavailable, per Martin Gallegos of MLB.com, despite not dealing with an injury and not having pitched since July 26. Jon Heyman of the New York Post reports that the Athletics and Padres are in discussions on a trade for Miller, and if the fireballing reliever were to be dealt, Perkins could be a candidate to ascend to the closer role.

Athletics' Jack Perkins: Claims first hold Saturday
Perkins collected a hold in Saturday's 8-2 win over the Guardians, striking out three while allowing no hits and one walk over three scoreless innings.
Perkins faced the minimum nine batters during his 31-pitch outing, and he atoned for the walk he issued to Carlos Santana to begin the bottom of the seventh by generating an inning-ending double play. Since being called up from Triple-A Las Vegas on June 22, the 25-year-old righty has looked sharp as a long man out of the bullpen, netting a pair of three-inning saves while accruing a 2.84 ERA, 0.87 WHIP and 14:4 K:BB in 12.2 frames. Manager Mark Kotsay has indicated Perkins will make starts for the Athletics before the end of the season, but his usage out of the bullpen Saturday suggests that he won't immediately fill the vacant spot in the club's rotation Tuesday in Texas.

Athletics' Jack Perkins: Option to join rotation
Athletics manager Mark Kotsay said recently that Perkins is an option to join the team's rotation out of the All-Star break, Jason Burke of Athletics on SI reports.
The Athletics closed out the first half with four starters in their rotation after optioning Mitch Spence to Triple-A Las Vegas. All four of Perkins' appearances in the majors have come in relief, but he went at least three innings in three of them and is also one of the club's better starting pitching prospects. Perkins has struck out 11 over 9.2 innings with the A's and has totaled 68 punchouts in 44 frames this season at Las Vegas. Kotsay also mentioned J.T. Ginn and Osvaldo Bido as potential options for the rotation.

Athletics' Jack Perkins: Secures another three-inning save
Perkins allowed two runs on three hits and struck out five without walking a batter over three innings to earn the save in Friday's 11-2 win over the Giants.
Perkins was scored upon for the first time in his major-league career when he gave up a solo home run to Brett Wisely in the eighth inning. He's maintained a starter's schedule despite pitching out of the bullpen in all three of his appearances with the Athletics, allowing just two runs on five hits and two walks with 10 strikeouts so far. He's also earned a pair of saves, but he's not in contention for closing duties while serving as a multi-inning reliever. There's no path to a starting role just yet, but Perkins has made an excellent first impression and will be a candidate to make starts if a rotation spot opens up.

Athletics' Jack Perkins: Impressive in multi-inning save
Perkins allowed one hit and two walks over 3.1 scoreless innings of relief Saturday to record his first career save in a 7-0 win over the Yankees. He struck out three.
The rookie right-hander has been outstanding over his first two big-league appearances, firing 6.1 scoreless innings with a 5:2 K:BB. Both outings have come in relief of JP Sears, who has a 5.09 ERA on the season even after Saturday's combined shutout. The fact that the A's are keeping Perkins stretched out and on the same schedule as the southpaw could be a sign the team plans to have him move into the rotation in Sears' spot sooner rather than later.

Athletics' Jack Perkins: Sharp in relief in MLB debut
Perkins struck out two batters and allowed one hit and no walks over three scoreless innings out of the bullpen in Sunday's 3-0 loss to the Guardians.
Perkins earned a call-up from Triple-A Las Vegas prior to Sunday's contest and was immediately put to work. He entered the contest in the top of the seventh while the Athletics faced a three-run deficit and proceeded to retire nine of the 10 batters he faced to finish out the game. Prior to his promotion, Perkins had been magnificent while working out of the Las Vegas rotation, logging a 2.86 ERA, 1.02 WHIP and 68:20 K:BB in 44 innings. Though he looks set to operate as a multi-inning reliever for the time being, Perkins will be leading candidate to start when an opening in the Athletics rotation emerges.

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: Unfazed by Pacific Coast League
Perkins has 0.79 ERA, 0.71 WHIP and 22:4 K:BB in 11.1 innings over his last two starts for Triple-A Las Vegas.
For the season, Perkins has a 3.23 ERA, 1.00 WHIP and a 61:15 K:BB in 39 innings in the hitter-friendly Pacific Coast League. He hasn't struck out fewer than seven batters in any of his last six starts and could be summoned to the majors at some point in the coming weeks.

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.
