Giants' Trevor McDonald: Logs 5.1 frames in no-decision
Rotowire
McDonald did not factor into the decision Monday, allowing three runs on nine hits and two walks over 5.1 innings against the Dodgers. He struck out four.
McDonald wasn't nearly as dominant in his second big-league start of the year compared to his seven-inning gem May 4 against the Padres, but he still was able to mitigate damage. The right-hander held the Dodgers scoreless through the first three innings before surrendering two runs in the fourth frame and a solo homer to Max Muncy in the sixth inning prior to being pulled. Through two starts, McDonald owns a 2.92 ERA and 1.05 WHIP with a 12:2 K:BB across 12.1 innings. With Logan Webb (knee) sidelined, McDonald figures to stick in the rotation for the time being, with his next start tentatively lined up for Saturday against the Athletics.

Giants' Trevor McDonald: Moving into rotation Monday
Rotowire
McDonald is slated to start Monday's game against the Dodgers in Los Angeles.
After being optioned to Triple-A Sacramento last Tuesday, McDonald was recalled just four days later after the Giants lost ace Logan Webb (knee) to the injured list. As expected, McDonald will end up moving into Webb's spot in the rotation Monday in what will be his second big-league start of the season. McDonald dazzled in his 2026 MLB debut with eight strikeouts over seven innings of one-run ball in a win over the Padres, but he's been far less stellar over a larger sample of five starts at Triple-A (5.40 ERA, 1.53 WHIP, 12:15 K:BB in 15 innings). He'll tentatively line up for two starts this week, with his second turn set to come over the weekend against the Athletics at hitter-friendly Sutter Health Park.

Giants' Trevor McDonald: Called up to fill rotation spot
Rotowire
San Francisco recalled McDonald from Triple-A Sacramento on Saturday.
McDonald's call-up is the result of Logan Webb (knee) landing on the injured list. It thus seems likely that McDonald will slide into Webb's spot in the rotation, and the former could make his next start Monday in Los Angeles against the Dodgers. McDonald impressed in his only outing with the Giants so this season, allowing one run on two hits and no walks while striking out eight batters over seven innings in a win over the Padres last Monday.

Giants' Trevor McDonald: Heading back to Triple-A
Rotowire
The Giants optioned McDonald to Triple-A Sacramento on Tuesday, Shayna Rubin of the San Francisco Chronicle reports.
McDonald tossed a seven-inning spot start Monday, allowing just one run on two hits and no free passes along with eight strikeouts. However, the top prospect is being sent back down to make room for Joel Peguero (hamstring), who was reinstated from the 15-day injured list Tuesday.

Giants' Trevor McDonald: Returned to Triple-A
Rotowire
The Giants optioned McDonald to Triple-A Sacramento on Friday.
McDonald had been up with the Giants to serve as their 27th man for Thursday's doubleheader with the Phillies. After going unused out of the bullpen in either contest, he was sent back to Sacramento, where he'll continue to work out of the rotation.

Giants' Trevor McDonald: Serving as 27th man
Rotowire
The Giants recalled McDonald from Triple-A Sacramento on Thursday.
He will be the team's 27th man for Thursday's doubleheader versus the Phillies. The Giants have not announced a starting pitcher for the nightcap, but McDonald is a candidate to draw that assignment or eat some innings in long relief. He holds a 5.40 ERA and 12:15 K:BB in 15 innings this season with Sacramento.

Giants' Trevor McDonald: Loses race for bullpen spot
Rotowire
The Giants optioned McDonald to Triple-A Sacramento on Tuesday, Shayna Rubin of the San Francisco Chronicle reports.
McDonald got off to a fast start this spring and looked to have a real chance at making the Giants' Opening Day bullpen as a long reliever. However, after finishing the Cactus League with a 6.94 ERA and 1.20 WHIP over 11.2 frames, he'll head to Sacramento to get back on track. The 25-year-old righty has looked good during his limited MLB opportunities (1.50 ERA, 0.89 WHIP through 18 IP), so the Giants may still be willing to add him to their rotation if injuries begin to arise among their starters.

Giants' Trevor McDonald: Fans 10 in first career win
Rotowire
McDonald (1-0) allowed three runs on five hits and struck out 10 without walking a batter over seven innings to earn the win over the Rockies on Friday.
McDonald gave up a three-run home run to Ezequiel Tovar in the fifth inning but was otherwise quite stingy in a dominant win. This was McDonald's third appearance in the majors this year, and he finished the campaign allowing six runs over 15 innings while adding a 14:2 K:BB. It was a strong showing in his late-season audition, which reflects better than his 5.37 ERA, 1.45 WHIP and 144:62 K:BB over 142.1 innings at Triple-A Sacramento. McDonald has likely done enough to be in the conversation for a big-league rotation spot in the spring.

Giants' Trevor McDonald: Drawing first MLB start Sunday
Rotowire
McDonald will start Sunday's game against the Dodgers in Los Angeles, Justice delos Santos of The San Jose Mercury Newsreports.
After being called up from Triple-A Sacramento on Tuesday, McDonald made his 2025 Giants debut later that night and pitched two innings out of the bullpen against the Diamondbacks, allowing two earned runs on three hits and a walk. He had been working out of the Triple-A rotation prior to his promotion, so he should be able to handle a traditional starter's workload Sunday, if the Giants desire. Tristan Beck, Carson Seymour and Spencer Bivens are candidates to cover multiple innings out of the bullpen if needed.

Giants' Trevor McDonald: Summoned to majors
Rotowire
McDonald was recalled from Triple-A Sacramento on Sunday.
The Giants are short on fresh arms for the final game of the regular season, so McDonald could make his big-league debut in relief of Hayden Birdsong. McDonald, a 23-year-old righty with decent stuff, logged 78.1 innings across High-A, Double-A and Triple-A this season.

Giants' Trevor McDonald: Returns from 7-day injured list
Rotowire
Double-A Richmond reinstated McDonald (groin) from its 7-day injured list Sunday.
McDonald has resided on Richmond's IL all season but is finally ready to join the Giants' Eastern League affiliate after an extended rehab assignment that first kicked off May 14.

Giants' Trevor McDonald: Rehabbing in Arizona
Rotowire
McDonald (groin) has turned in a 5.79 ERA, 1.90 WHIP and 4:2 K:BB in 4.2 innings through four rehab outings in the rookie-level Arizona Complex League.
McDonald has resided on Double-A Richmond's 7-day injured list all season while healing up from a groin injury, but he may not be far away from making his 2024 debut for the Giants' Eastern League affiliate. He's yet to pitch at the Double-A level but was dominant during his time at High-A Eugene in 2023, pitching to a 0.96 ERA, 0.86 WHIP and 39:8 K:BB in 37.2 innings.

Giants' Trevor McDonald: Out with groin injury
Rotowire
McDonald is on the injured list at Double-A Richmond with a groin injury, Jim Callis of MLB.com reports.
McDonald is a nice sleeper prospect for dynasty leagues, as he has excellent control and could potentially get to pitch half his games in the pitcher-friendly park in San Francisco. In his age-22 season, McDonald logged a 1.33 ERA, 0.93 WHIP and 51 strikeouts in 47.1 innings across 14 appearances in the lower levels of the minors. He averaged 94 mph with his two-seam fastball last year (touching 98 mph) and had a groundball rate north of 70 percent. McDonald also sports a plus curveball, while mixing in a four-seamer and a slider.

Giants' Trevor McDonald: Optioned by San Francisco
Rotowire
McDonald was optioned to minor-league camp by the Giants on Monday, Susan Slusser of the San Francisco Chronicle reports.
McDonald was added to the 40-man roster over the winter, but he was never going to make the club given that he's yet to advance past A-ball. The 23-year-old missed much of last season with arm issues but pitched very well when healthy, 0.96 ERA and 0.86 WHIP in 37.2 innings at High-A Eugene.

Giants' Trevor McDonald: Protected from Rule 5 Draft
Rotowire
The Giants added McDonald to their 40-man roster Tuesday.
Rather than risking losing McDonald in the upcoming Rule 5 Draft, the Giants will give the 22-year-old righty a spot on their 40-man. McDonald spent the early stages of the season working his way back from an arm injury before posting a dominant 0.96 ERA and 0.86 WHIP in 37.2 innings at High-A Eugene. It's possible the Giants bump McDonald up to Double-A to begin the 2024 campaign.

Giants' Trevor McDonald: Returns from IL
Rotowire
McDonald (arm) was reinstated from High-A Eugene's 7-day injured list May 5 and made his season debut a day later, covering three innings and giving up one earned run on four hits and two walks while striking out three in a 4-2 win over Spokane.
McDonald spent the first month of the season on the shelf after he fell behind Eugene's other starting pitchers in his throwing program and required more time to build up at extended spring training. The Giants will likely be cognizant about managing the 22-year-old right-hander's innings this season, but he should be able to make one start or extended relief appearance per week now that he's back from the IL.

Giants' Trevor McDonald: On IL at High-A
Rotowire
McDonald is on the 7-day injured list with High-A Eugene and is building up arm strength in extended spring training, Jim Callis of MLB.com reports.
A 22-year-old righty, McDonald split time as a starter and reliever en route to logging a 2.31 ERA, 1.25 WHIP and 120 strikeouts in 101.1 innings at Single-A and High-A last season. It's unclear how much time he will need before he is ready to rejoin the High-A pitching staff.
