TORONTO -- An ankle injury is making things even worse for Troy Glaus' already troublesome left foot.

The Blue Jays' third baseman has been playing through bone spurs in his left heel for the majority of the season. On Tuesday, Glaus was left out of the lineup for the second consecutive day for what was originally believed to be the same injury. Turns out, it's actually a sore ankle and Glaus was scheduled to be checked out by doctors prior to the start of Tuesday's series opener against the Angels.

"The ankle and the heel are two different things. The ankle has been bugging him now for a while," Jays general manager J.P. Ricciardi said. "The doctors are looking at his ankle and we'll have a better idea of what can be done and what can't be done. It might be a surgery in the offseason, just to clean it out."

With the Jays still clinging to their goal of getting back into the American League Wild Card race, they are hoping with some treatment, Glaus will be able to come back and finish the rest of the season. He's currently listed as day-to-day and season ending surgery is not an option, at least for now.

Glaus' injury woes could help explain his recent struggles at the plate. On July 16, Toronto's slugger was hitting .296, but since that time has gone 12-for-86 (.140). His batting average has plummeted down to .253.

Included in his recent slump was a career-worst 0-for-27 skid that he snapped on Saturday with a two-hit night. Manager John Gibbons wasn't about to offer up any excuses for his third baseman, but he understands how the type of injury Glaus' has could affect his performance at the plate.

"Those are his feet, it's your balance, it's everything," Gibbons said. "It could have -- but I don't think he'd say that."

In Glaus' absence, newly acquired Hector Luna got the start at third base for the second straight game. Toronto claimed Luna off waivers from the Indians on Aug. 3. Gibbons said utility infielder Ray Olmedo could also see some time at the hot corner against right-handed starting pitchers.

Familiar face: On Tuesday, former Jays reliever Justin Speier made his return to Rogers Centre for the first time since signing with the Angels as a free agent during the offseason. Speier spent the last three seasons with Toronto, going 8-10 with a 3.37 ERA.

It's been an up and down year for the right-hander. When he's been healthy, Speier has been the type of late-inning presence Los Angeles was hoping for when they signed him to a four-year, $18 million contract. But the 33-year-old was forced to miss more than a month and a half earlier this year because of a mysterious intestinal virus that caused him to lose 10 pounds.

"They don't know how it was caused," Speier said. "It was just one of those things where I started losing weight and I started having some insomnia. My stomach was in knots almost all the time -- especially when I started doing a lot of physical activity."

Speier's departure was expected to create a large hole in the Jays late-inning relief corps. But the emergence of Toronto right-handers Casey Janssen and Jeremy Accardo have helped make a seamless transition. The Jays bullpen currently ranks third in the AL with a 3.53 ERA.

"It's unbelievable," Speier said. "I'm really proud of them. It's been to see how they've come into their own as pitchers. It's been a pleasure to watch -- their progression."

Trouble on the basepaths: Toronto currently ranks last in the American League in caught stealing percentage. Jays catchers have managed to throw out 15 baserunners in 118 attempts this season, which equals just under 13 percent.

Things aren't going to get any easier for Toronto's backstops during their three-game series against the Angels. Los Angeles leads the AL in stolen bases with 107 this season. In the first inning of Tuesday night's game, Angels third baseman Chone Figgins singled to right and then stole second on the very next pitch.

"They've got guys who could steal them off anybody," Gibbons said. "That's part of the game. We've got to keep them off base."

Moving on up: Jays center fielder Vernon Wells recorded his 1,015st career hit on Monday night in Kansas City. He is now tied with Joe Carter for the fifth most in franchise history. Former Jays shortstop Tony Fernandez is all-time leader with 1,583.

Down on the farm: Right-hander Connor Falkenbach set a Double-A Dunedin single season record on Sunday by notching his 27th save of the season. ... On Monday, right-hander Julio Pinto was named the Midwest League's Pitcher of the Week. Pinto went 1-0 with a 0.87 ERA in 10 1/3 innings pitched for Class A Lansing.

Coming up: Shaun Marcum (9-4, 3.43 ERA) is scheduled to take the mound for Toronto when the Blue Jays host the Angels at 7:07 p.m. ET on Wednesday night at Rogers Centre. Anaheim will counter with right-hander Dustin Moseley (4-1, 4.93).
