Chacin heads to 15-day disabled list

Blue Jays place Chacin on DL

TORONTO -- Blue Jays starter Gustavo Chacin cut his scheduled bullpen session short Monday afternoon after feeling pain in his left shoulder. That's the last thing the club needed, considering seven other players have spent time on the disabled list this month.

On Monday, Chacin became the eighth, equaling the number of Blue Jays who landed on the DL all of last season. Toronto placed Chacin on the 15-day DL and manager John Gibbons wasn't sure what the next step would be for the left-hander.

"His shoulder was sore after he threw his bullpen today," Gibbons said after Toronto's 6-1 win over Texas. "We're just going to DL him and see where we're at after a couple days."

Chacin packed his bags after the game, prepping for Toronto's flight to Cleveland on Monday night. The pitcher will remain with the team at least through Tuesday, when the Jays open a three-game set against the Indians at Jacobs Field. If the discomfort is still a major issue in the next few days, Chacin will likely see a doctor to further evaluate the extent of the injury.

"It's pretty bad, but this happens sometimes," Chacin said. "You have to be strong. I hope it's nothing really bad -- that it's something really light and I can come back soon. We'll see tomorrow. I'm going to Cleveland tonight, and tomorrow we're going to decide what's going on."

Chacin was originally slated to start for the Blue Jays on Thursday against the Indians. With him temporarily out of the picture, Gibbons said Toronto will promote someone from Triple-A Syracuse to replace Chacin in the rotation. Toronto's manager declined to reveal which starter that would be, though.

A leading candidate appears to be right-hander Dustin McGowan, who is 0-2 with a 1.64 ERA in five starts for the Chiefs this season. The 25-year-old also has 29 strikeouts vs. nine walks over 22 innings.

McGowan is 2-5 with a 6.69 ERA in 29 games, including 10 starts, in his career with Toronto. He last started for Triple-A Syracuse on Saturday, which means he'd be coming off a perfect four days of rest in order to take the mound on Thursday.

"He could be," said Gibbons, when asked if McGowan was an option. "We'll have somebody come up for that Thursday start, but we just don't know who that is yet. It'll be somebody from Triple-A."

Chacin, 26, last started for Toronto on Saturday, when he turned in 5 1/3 innings in a no-decision against the Rangers. The native of Venezuela indicated that he had no pain in his shoulder during that outing, or in any of his four previous starts.

The issue first flared up on Monday, when Chacin began throwing in a regularly scheduled side session. He played catch with no issues before taking the hill, but began to feel something in his shoulder while throwing pitches off the mound.

"I was feeling it when I started throwing," Chacin said. "Something in my shoulder bothered me."

The ailment is unrelated to the injury that sidelined Chacin for more than two months last season. That problem stemmed from a sprained ulnar collateral ligament in Chacin's left elbow. He still was able to make 17 starts for the Jays, going 9-4 with a 5.05 ERA.

In five starts this season, Chacin was 2-1 with a 5.60 ERA. The southpaw had 11 strikeouts and seven walks, and had allowed 29 hits over 27 1/3 innings. During his career with Toronto, Chacin has compiled a win-loss record of 25-14, including a 13-9 mark during his rookie campaign in 2005.

Chacin is one of seven players currently on the DL for the Blue Jays. The others are outfielder Reed Johnson (lower back), closer B.J. Ryan (left elbow), catcher Gregg Zaun (right hand), starter John Thomson (right shoulder), reliever Brandon League (right shoulder) and reliever Davis Romero (left shoulder). Toronto third baseman Troy Glaus was activated from the 15-DL on Saturday after missing two weeks with a bone spur in his left heel.
