Del Rosario called up to replace Lyles on roster.— Alyson Footer (@alysonfooter) May 21, 2012
Del Rosario, 26, has 65 professional innings under his belt and sports a 4.57 ERA between his time with the Cincinatti Reds and the Astros. He has seen just two innings of work in the pros this season, giving up one walk, two hits, and one earned run while striking out one. Del Rosario is just as likely to walk a batter as strike him out and has an unlikely 1-1 strikeout-to-walk ratio for his career.
Lyles, 21, started fifteen games for the Astros in 2011, going 94 innings at a 5.36 ERA clip. He was optioned to Oklahoma City to start the 2012 season, but was recalled back to Houston on April 29 to make a start for Kyle Weiland while he was on the DL. Lyles has seen three starts and seventeen innings in 2012 while earning a 5.29 ERA on the season.
Lyles was optioned back to Oklahoma City yesterday.
