Neftali Feliz, Derek Holland, and Alexi Ogando are on the disabled list, Roy Oswalt is scuffling in the minors, and Scott Feldman is 0-6 with a 6.50 ERA, so the Rangers have decided to dip down to Double-A for their latest rotation reinforcement.
Justin Grimm will be called up from Double-A to make his big-league debut Saturday against the Astros, which the 23-year-old right-hander admitted was “kind of unexpected, to be honest.”
Grimm has pitched extremely well at Double-A, throwing 77 innings with a 1.73 ERA and 67/14 K/BB ratio, and had just been named a Texas League All-Star when he got the news. However, he’s also not considered a top prospect and has made just 13 total starts above Single-A.
It’s hard to imagine Grimm sticking in the majors even if he thrives initially, but for now the Rangers are just looking for some short-term help while waiting on Oswalt to show he’s ready.
