The left-hander led the team with 201 innings pitched, 10 victories and a 3.77 ERA in 2003. However, he is 0-3 with a 7.32 ERA this season, and was forced to leave his last start, at Minnesota on April 24, due to a strained left groin.
May, who was on the disabled list twice in 2002 with groin strains, allowed one run on four hits and two walks in 4 1-3 innings before leaving in the Royals’ 10-1 victory.
He missed one start, but had a successful bullpen session on Saturday.
“It was the worst conditions—windy, rainy, wet and cold—and I felt fine,” May said. “I have to get this out of my system and move forward. I ran afterward and everything went great. That’s really good news. The last thing I want is to be pushed back or go on the disabled list.”
Royals starters, just 2-10 this season, have already been hit by injuries. Three pitchers are out for the season due to surgeries and three, including May, have left an outing with injuries in the last nine games.
Kevin Appier, who was out much of last year due to elbow surgery, left after two innings with a right forearm strain on April 25 and is expected to miss four to six weeks.
Jimmy Gobble exited in the sixth inning Wednesday with muscle cramps from dehydration. Gobble, though, made his next scheduled start against Toronto on Monday and pitched a stellar game. He retired his first 16 batters and gave up two runs on five hits with no walks over 8 2-3 innings as the Royals beat the Blue Jays 3-2 in 10 innings.
The Blue Jays lost for the sixth time in seven games and dropped to 1-9 at SkyDome. They are 1-7 against left-handed starters and will face a third straight lefty, Brian Anderson, on Wednesday.
“You’d like to be rewarded for your hard work, but no one here is giving up,” manager Carlos Tosca said.
Toronto lost its first eight games at home before beating Boston 7-3 on April 22, and plays nine of its next 12 games at SkyDome.
