The Rockies have acquired righty reliever Jason Grilli from the Tigers. Grilli has pitched in 9 games (0 starts) for the Tigers this season and he was 0-1 with a 3.29 ERA and a 1.39 WHIP. He has now pitched in 136 games (16 starts) in his major league career and he is 13-13 with a 5.08 ERA and a 1.46 WHIP. To get Grilli the Rockies sent 22-year old righty reliever Zach Simons to the Tigers. Simons has pitched in 7 games (0 starts) in A ball and he is 1-0 with a 2.70 ERA and a 1.58 WHIP. This was a good trade for the Rockies who needed help in the bullpen now.
