Giants' Trevor McDonald: Logs quality start in loss
Rotowire
McDonald (2-2) took the loss Wednesday against the Diamondbacks, allowing three runs (two earned) on six hits and two walks over 6.1 innings. He struck out six.
McDonald was sharp Wednesday, blanking the Diamondbacks through five innings. However, he'd give up two runs in the sixth and another in the seventh, which proved to be enough to stick him with the loss in a 3-2 defeat. Still, it was a nice bounce-back performance from McDonald after he was tagged for seven runs in 3.2 innings his last time out against the White Sox. It remains to be seen whether or not the 25-year-old McDonald will remain in San Francisco's rotation, with Logan Webb (knee) expected to return this weekend.

Giants' Trevor McDonald: Will get another start
Rotowire
McDonald will start Wednesday's game at home versus the Diamondbacks, Justice delos Santos of The San Jose Mercury News reports.
With Logan Webb (knee) slated to rejoin the rotation this weekend, it could be McDonald's final start with the big club before he's sent back to Triple-A Sacramento. McDonald has offered more good than bad with the Giants but was roughed up his last time out, yielding seven runs over 3.2 frames.

Giants' Trevor McDonald: Roughed up by White Sox
Rotowire
McDonald (2-1) allowed seven runs on three hits, one walk and two hit batsmen while striking out four over 3.2 innings to take the loss versus the White Sox on Friday.
McDonald was perfect the first time through the order but completely unraveled in the fourth inning. He was pulled after giving up five runs, but Ryan Borucki also struggled, allowing two inherited runners to score. This was a terrible time for McDonald to have a bad start, as it came on the same day Logan Webb (knee) was making his first, and likely only, rehab start. McDonald is now at a 4.76 ERA, 1.01 WHIP and 21:4 K:BB through 22.2 innings over four starts in the majors this year. His performance Friday likely made the Giants' decision easier when they need to clear a 26-man roster spot for Webb's return next week, though an official decision from the team is likely a few days away.

Giants' Trevor McDonald: Pitches into seventh inning again
Rotowire
McDonald (2-0) allowed one run on five hits, a walk and a hit batsman while striking out five over 6.2 innings to earn the win Saturday over the Athletics.
McDonald has shown the ability to provide length early in his stay in the majors, which could help him stick around even when Logan Webb (knee) is healthy, though McDonald's status is not guaranteed. Through three starts with the Giants this season, McDonald has a 2.37 ERA, 1.00 WHIP and 17:3 K:BB over 19 innings. His role could get some clarity in the near future with Webb eligible to be reinstated from the injured list next week.

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: Earns victory in season debut
Rotowire
McDonald (1-0) earned the win over San Diego on Monday, tossing seven innings during which he allowed one run on two hits and no walks while striking out eight batters.
McDonald is one of San Francisco's top pitching prospects and was called up from Triple-A ahead of Monday's matchup. He had previously thrown 18 major-league innings across the 2024-25 campaigns. The right-hander was very impressive in his first start of 2026, racking up eight punchouts with no walks while breezing through seven frames on just 81 pitches. The only run he gave up came on a first-inning homer by Jackson Merrill. McDonald certainly pitched well enough to earn another start, but there isn't an obvious spot for him in the Giants' rotation, so it will be interesting to see what San Francisco opts to do with him moving forward.

Giants' Trevor McDonald: Recalled ahead of Monday's start
Rotowire
The Giants recalled McDonald from Triple-A Sacramento ahead of his start against the Padres on Monday.
McDonald served as the Giants' 27th man for Thursday's doubleheader against the Phillies, though he went unused out of the bullpen. Southpaw reliever Erik Miller (back) was placed on the 15-day IL in a corresponding move, so Monday's outing will likely be a spot start for McDonald. The 25-year-old right-hander has appeared in five games (four starts) in Triple-A and has a 5.40 ERA and 1.53 WHIP across 15 innings.

Giants' Trevor McDonald: Set for big-league start Monday
Rotowire
McDonald is slated to be called up from Triple-A Sacramento to start Monday's series opener against the Padres.
The Giants optioned McDonald to Triple-A on Friday, but the fact that he's being listed as the team's probable starter for Monday suggests that another player will be placed on the injured list in a corresponding move to facilitate his call-up. The right-hander has appeared in five contests (four starts) with Sacramento this season, posting a 5.40 ERA, 1.53 WHIP and 12:15 K:BB over 15 innings. Unless San Francisco ends up deactivating one of the five members of its rotation Monday, McDonald will likely be in line for just a spot start before heading back to Triple-A.

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: In mix for bullpen spot
Rotowire
McDonald has allowed two hits and a walk while striking out seven across six scoreless innings in three Cactus League appearances, and he is making a strong case to open the 2026 campaign in the Giants' bullpen, Maria Guardado of MLB.com reports.
McDonald was recalled from Triple-A Sacramento in September of last season, recording a 1.80 ERA, 1.00 WHIP and 14:2 K:BB across 15 innings in three big-league appearances, including two starts. The right-hander has impressed this spring, and while there isn't expected to be room for him in the starting rotation just yet, he has a good chance to open the season in the bullpen. If injuries arise among San Francisco's starters during the season, the 25-year-old would be a candidate to move into the rotation.
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: Picking up another start
Rotowire
McDonald is slated to start Friday's game against the Rockies in San Francisco.
The rookie right-hander will be awarded another turn through the rotation after he performed well against the Dodgers in his first MLB start this past Sunday, striking out three while allowing one earned run on six hits and one walk over six innings. McDonald will look to build on that performance with another positive outing against the Rockies, which could improve his chances of being part of the Giants' Opening Day rotation in 2026.

Giants' Trevor McDonald: Shows well in first start
Rotowire
McDonald allowed one run on six hits and a walk while striking out three over six-plus innings in a no-decision Sunday versus the Dodgers.
McDonald went pitch-for-pitch with Emmet Sheehan over the first six innings. In the seventh, McDonald put three straight batters on base, leading to the lone run on his line, before Spencer Bivens relieved him and put out the fire. McDonald has given up three runs while posting a 4:2 K:BB across eight innings over his two major-league outings this season. If he did enough Sunday to earn another turn through the rotation, that would likely come in a home matchup versus the Rockies in the final series of the season.
