After leaving the first game of yesterday's double header against the Colorado Rockies, the Arizona Diamondbacks have placed reliever Juan Gutierrez on the disabled list. He was seen pointing to his shoulder as he left the field, and the official diagnosis is indeed "right shoulder inflammation."
Gutierrez was struggling so far this year with the team - either being lights-out and allowing no runs to score, or throwing less than an inning and allowing multiple run to come across. In his past two outings, he allowed 4 earned runs in 1/3rd of an inning. He's also given up 3 home runs in 18.1 innings pitched.
His replacement is Zach Kroenke from AAA Reno. Kroenke was a September call-up last year and struggled mightily as a reliever, but had a solid start against the Dodgers. In 8 starts this year in Reno, he is 4-0 with a 5.64 ERA, 5 home runs, 14 walks and 22 strikeouts. No official word on him going to the bullpen, but with Guti out and Zach Duke coming up on Saturday, Kroenke will likely find himself in the bullpen as a long reliever.
