Martin didn't factor into the decision in Saturday's 7-3 win over the Red Sox, giving up three runs (two earned) on five hits and four walks over four-plus innings. He failed to strike out a batter. The rookie's second big-league start did not go as smoothly as his first, as he threw only 38 of 74 pitches for strikes and gave up hits to the first two batters he faced in the fifth inning before being bailed out by Josh James. Martin will next take the mound Thursday, at home against the White Sox, but if he continues to struggle with his control the Astros have plenty of other rotation options they could use to replace the 23-year-old.
Martin (1-0) gave up two runs on three hits and one walk while striking out nine through 5.1 innings Sunday, earning the win over the Rangers. Martin only allowed a solo home run before walking Shin-Soo Choo to start the sixth inning and being pulled after 80 pitches. Collin McHugh allowed the runner to score, but the Astros provided 15 runs of support to ensure the first win of Martin's career. Martin will make his next start Saturday at the Red Sox.
The Astros officially selected Martin's contract from Triple-A Round Rock ahead of his scheduled start Sunday against the Rangers, Chandler Rome of the Houston Chronicle reports. Jose Altuve (hamstring) was moved to the 10-day injured list to open up a spot on the active roster for Martin, who will assume the struggling Collin McHugh's rotation spot. Martin's stay with Houston will likely be dictated by how well he performs in his first taste of the big leagues, but expectations are fairly high for the 23-year-old right-hander. Regarded as one of Houston's top pitching prospects heading into the season, Martin validated that status by compiling a 1.48 ERA and 28 strikeouts over 24.1 innings with Round Rock.
Martin is expected to have his contract purchased from Triple-A Round Rock and make his big-league debut Sunday against the Rangers, Jake Kaplan of The Athletic reports. Martin will start in place of the struggling Collin McHugh and could have the chance to stick around should he impress in his first start. The 26-year-old has a 2.31 ERA in 179 career minor-league innings, striking out 27.5 percent of opposing batters while walking 7.9 percent. He projects as a future mid-rotation starter with average command, an above-average changeup and a plus slider.
Martin threw 4.1 scoreless innings in relief Thursday against the Dodgers' Triple-A affiliate Oklahoma City. He struck out six while allowing a hit and two walks. Most of Martin's appearances have come as a starter, but this was a planned relief appearance. Through 20.1 innings so far with Triple-A Round Rock he has a 1.33 ERA and 1.00 WHIP, with a 25:10 K:BB.
