This twitter message from the Mariners' beat writer says the Astros signed relief pitcher Roy Corcoran, whom was released by the Mariners after refusing a minor league assignment. This seems OK if it is a minor league deal, but the fact that Corcoran left the Mariners because he wanted to stay in the majors makes me wonder if he will soon be on the Astros roster. Corcoran is a heavy groundball pitcher who walks too many batters, doesn't strike out many batters, and has had both good and bad seasons in the past. He is in the middle of a bad year, with a 6.16 ERA and a FIP somewhat north of the ERA. Last year he was regarded as one of the better Mariners' relief pitchers with a 3.22 ERA and 3.74 FIP. Corcoran's walks seem to have been his undoing this year. I wonder if this means we won't see Gervacio recalled the next time the Astros make a roster move to beef up the bullpen. Corcoran is 29 years old.
