BALTIMORE -- Rommie Lewis is going to the team's Florida complex to have his throwing shoulder checked out.

Lewis has no record and a 6.75 ERA in 14 games with the Jays. He was recalled from Triple-A Las Vegas on Sept. 5 and has made just one appearance since then. Pitching coach Bruce Walton said the problems with his left shoulder were also there when Lewis pitched in Triple-A. The team just wants to check everything out since it's a problem that's been around.

Manager Cito Gaston and others said it's kind of a continuation of something that's been bugging the left-hander.

"He was a little sore in Vegas, it's stems back to Triple-A, and what was going on there," said Walton. "It was just minor tightness, but they're just going to check it out and see how he is, give him a clean bill of [health] before he goes back out there and pitches again."

Lewis last pitched on Sept. 11 against the Rays, giving up four earned runs and four hits in just one-third of an inning. He had pitched 13 games with the Jays earlier this season.

Buchholz getting ready for action with Jays

BALTIMORE -- The Jays claimed right-hander Taylor Buchholz off waivers from the Rockies on Sept. 9, and manager Cito Gaston said it will be a few more days before he sees action.

Gaston said Toronto is trying to be careful with Buchholz, because he's recovering from Tommy John surgery. He missed the 2009 season after having the operation.

"Hopefully, probably by the time we get to Boston, he might be OK," said Gaston. "We brought him up, we want to see what he can do. He had good numbers ... usually guys come back [from the surgery] throwing better."

Buchholz pitched for Triple-A Colorado Springs in the first part of 2010, with a 1-1 record and a 5.06 ERA in 21 games. He made one start.

Worth noting

One reason the Jays won their first 12 games against Baltimore this season was their hitting. Toronto has an impressive .283 batting average in its 13 games against the Orioles. The Jays have scored 73 runs, averaging almost six runs per game. ... September certainly hasn't been kind to the Toronto pitching staff. The Jays' pitchers have a record of 4-8 with a 5.50 ERA so far this month. In addition, they've given up 123 hits and 53 walks in 106 1/3 innings. The starters have experienced even more problems. They've posted a 6.23 ERA in 60 2/3 innings.
