Montgomery (elbow) will be shut down from all throwing activities for 2-to-3 weeks with an initial timetable of 6-to-8 weeks before he returns to the big-league club, Sweeny Murti of Sportsradio 66 WFAN reports. Montgomery landed on the 10-day disabled list due to a left elbow flexor strain that he suffered during Tuesday's outing in Houston. The club has yet to confirm who will be taking Montgomery's place in the rotation, but Domingo German appears to be the best bet.
Montgomery was placed on the 10-day disabled list with a left elbow strain Wednesday. The southpaw was lifted from Tuesday's contest after just one inning of work due to elbow soreness, but that has since been upgraded to a full-blown elbow strain. It's unclear how long he'll be out, but elbow injuries are never a good sign for pitchers. David Hale will replace Montgomery on the active roster, though Domingo German seems like the top candidate to slide into the rotation to replace him.
Montgomery exited Tuesday's game against the Astros early with left elbow tightness, Erik Boland of Newsday reports. Montgomery suffered the injury during his tidy seven-pitch first inning Tuesday. He'll return to New York on Wednesday to undergo further testing on his irritated elbow. A more concrete diagnosis of his injury should become available following those tests.
Montgomery allowed two runs on four hits and three walks across five innings in a no-decision against the Twins on Thursday. He struck out six. It was another solid, but not spectacular, effort from Montgomery. His six strikeouts were a season high, but walks once again prevented the young lefty from pitching deep into the game. It's still early, but Montgomery now owns a 4.1 BB/9 through five starts this season -- all of which have lasted six or fewer innings -- after posting a 3.0 BB/9 across 29 starts in his rookie season. He'll carry a 3.76 ERA into his next start, which is scheduled for Tuesday in Houston.
Montgomery improved to 2-0 on the season after tossing six innings and allowing just one run on four hits -- all singles -- Saturday against the Blue Jays. He struck out five and walked three. Montgomery has continued to pitch like a solid back-end starter this season. He hasn't struck out a batter per inning in any of his four starts but has allowed three runs or less in three of them. He was rarely in real trouble Saturday, letting in just one run after a small rally to start the fifth inning. His ERA now sits at a solid 3.80, and while his 4.53 xFIP suggests that he's due to slide back a bit, those numbers are a near match for the 3.88 ERA and 4.45 xFIP he posted in his rookie season, so it's possible he has the ability to slightly outperform his peripherals. Montgomery will next take the mound Thursday against the Twins.
