Boof Bonser is on Boston’s disabled list because of a right groin strain.
After his second rehabilitation start Tuesday for Triple-A Pawtucket, Bonser’s more concerned about his surgically-repaired right shoulder.
Bonser gave up nine earned runs in two innings against Lehigh Valley in an International League game won 12-0 by the IronPigs.
Lehigh Valley sent 11 batters to the plate in the second and scored eight runs on four hits, three walks, one hit batter, a wild pitch and an error.
“We had a long (first) inning and I had some stiffness in my shoulder, ‘’ Bonser said who underwent surgery on February 25, 2009 to repair a torn rotator cuff. “I think it definitely affected that second inning. I was favoring the shoulder a little bit and was throwing it up there and, hopefully, let them try to get themselves out.
“Obviously, they didn’t miss much.”
Bonser, who was on a 90-pitch count, threw only 50 pitches including 26 for strikes.
He reached 92 mph on McCoy Stadium’s radar gun.
Former major leaguer Cody Ransom hit a two-run homer off Bonser which capped Lehigh Valley’s eight-run second.
“The cold weather is a big change for me,” Bonser said. “It’s basically been a full year since I pitched and when I did this year (in spring training), it was in Florida in warm weather. Coming up here the cold weather is getting to me and I think it got to me big time today.
“My leg’s good. I would definitely say the shoulder is more of a concern. I’m only a year and three months away from surgery. I would say I’m worried about it but I’ve got to see how it reacts.”
The fact Bonser only was able to pitch two innings also was a source of frustration.
“Obviously when you only go two innings and your shoulder doesn’t feel good, especially coming off surgery, it’s not a great day,” he said. “It was fine warming up. But sitting there when it was a little chilly, (the arm) seized up on me and they had a big inning.”
Bonser, who is tentatively scheduled to make another rehab start on April 19 at Rochester, is 0-1 with a 17.14 ERA over 6 1/3 innings in his two appearances for Pawtucket.
“He is going to get discouraged but Boof understands where he’s at,” Pawtucket manager Torey Lovullo said. “I think he’ll spit these two outings out of his head.
“I’m confident Boof won’t have a setback.”
