The Yankees have lost LHP Jordan Montgomery to Tommy John surgery, weakening their already-thin starting rotation depth.
Montgomery, who was already out due to a flexor strain, will have surgery on Thursday, with recovery expected to be between 12 and 18 months.
Domingo German has been in the Yankees' rotation in German's place.
Montgomery, 25, had a 3.62 ERA (4.18 FIP) and 1.35 WHIP with 23 strikeouts in 27.1 innings (six starts) this season.
This was the news that many feared when Montgomery first went down.
We have been under the assumption that the Yankees are going to be invested in the starting pitcher market this summer, and this only amplifies the need as they may have hoped to eek some production out of Montgomery in the latter part of the season.
The trade market has not fully developed and in this day and age of the second wild card, it could take some time for middling teams to decide whether they are buyers or sellers. As such, the Yankees will have to continue to rely on an inconsistent rookie in German to develop on the job and minimally keep the team in games -- as he did Monday night.
If German falters, it might force the Yankees to push a pitcher like their top pitching prospect, Justus Sheffield, into the picture a bit earlier than expected.
