Trevor McDonald: Everything you need to know

McDonald (2-3) took the loss Tuesday against the Brewers, allowing three runs on five hits and three walks with four strikeouts across five innings. McDonald got into trouble in the first inning, walking each of the first two batters before serving up a three-run homer to Jake Bauers. The right-hander settled in the rest of the way, but the damage was done, and the San Francisco offense was unable to do much of anything against Kyle Harrison. In six starts this season, McDonald has a 4.50 ERA, 1.15 WHIP and 31:9 K:BB across 34 innings, and he's lost three straight games. He's lined up to face the Cubs at Wrigley Field on Sunday.

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.

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.
