Corcoran, the right-handed Mariners reliever who has been on the disabled list since April 30 with a strained neck, threw 33 pitches in a simulated game to various Mariners hitters and pitchers before Seattle's 3-2 win over Baltimore, and said he felt better than at any point in 2009.
"Everything went good," said Corcoran, who had compiled a 1-0 record, a 7.27 ERA and had walked nine batters in 8 2/3 innings over eight appearances this season before he went on the DL. "I felt fine, I threw it where I wanted it most of the time, and now I'll just sit back and wait and see what they have to say."
For now, "they," aka manager Don Wakamatsu and the rest of the Seattle brass, will have Corcoran start a rehab assignment at Triple-A Tacoma this weekend.
Corcoran, who impressed the team in late 2008 with his ability to induce grounders and his mound composure, said he has no pain in his neck.
"As far as health, I feel real good," he said. "[Today was] probably the best my breaking ball's been in two years. It looked good today. But I felt like my legs are under me a little more, I stayed inside my lead leg, wasn't falling off the mound so much and getting away from twisting the upper body."
Corcoran said being on the DL for over a month has been a blessing in one regard: the rest has taken care of arm soreness that had crept up on him and didn't go away with regular treatment that had routinely calmed it down in the past.
Other than that, he said he hasn't been told anything about when he might be ready to rejoin the Major League bullpen. Wakamatsu said the team would like for Corcoran to use his rehab time to iron out some command issues so he's healthy and throwing strikes when he returns.
Corcoran said he's done continually asking the team when he'll be back.
"I'm tired of fighting it," he said. "I'm tired of asking what I'm doing and where I'm going. ... Hopefully, I'll be back out there soon."
