The Astros have placed 25-year old righty reliever Rhiner Cruz on the 15-day disabled list due to an ankle sprain. Cruz has pitched in 7 games (0 starts) for the Astros so far this year and he is 1-0 with a 2.08 ERA and a 1.15 WHIP. The Astros have called up 26-year old righty Enerio Del Rosario to replace Cruz in the bullpen. Del Rosario has pitched in 11 games (0 starts) in AAA-ball this year and he is 0-1 with a 3.14 ERA and a 1.26 WHIP there. He pitched in 54 games (0 starts) for the Astros last year and he was 0-3 with a 4.58 ERA and a 1.70 WHIP. The Astros hope that Del Rosario will do a solid job for them until Rhiner Cruz is ready to return to action.
