Reyes advancing through ranks in rehab

TORONTO -- Jose Reyes appeared in his final rehab game for Class A Dunedin on Wednesday afternoon and will now advance to Triple-A Buffalo.

Reyes played seven innings and went 2-for-4 with an RBI and a run. The shortstop finished a three-game stint in Class A with five hits in 13 at-bats (.385) while scoring three runs and stealing a base.

The 30-year-old will enjoy an off-day on Thursday before joining the Bisons on Friday. He's expected to play at least three games for them as he continues to build endurance and work on his timing at the plate.

"He'll play in Buffalo on Friday night and through the weekend," manager John Gibbons said. "We'll see where he's at into the weekend."

Gibbons remained non-committal when asked about a timeline for Reyes' return. The club originally said Reyes could require two weeks of rehab games before coming back, but it's still possible he could rejoin the Blue Jays on Monday in Tampa Bay for the start of a three-game series.

The Dominican native has been out since suffering a severely sprained ankle on April 12 in Kansas City. He'll assume his regular spot at the top of the lineup once healthy, as Melky Cabrera is expected to slide down to the No. 5 spot in the order.

Reyes hit .395 with three extra-base hits in 10 games before his injury. He was slated to be out until the All-Star break, but he had his ankle heal faster than expected and will be back before the end of June barring any setbacks.

No structural damage to Morrow's forearm

TORONTO -- Blue Jays starter Brandon Morrow has received some good news about his injured right forearm.

Morrow underwent an MRI on Tuesday and the results came back negative. There isn't any structural damage in the area, and it appears as though he's just dealing with inflammation.

The 28-year-old Morrow will remain in a no-throw situation until discomfort in the area subsides and he's ready to increase the intensity of his workouts.

"There wasn't anything unusual, there was just some inflammation in his forearm," Blue Jays manager John Gibbons said. "We'll just back him off and rest him until he's ready."

Morrow, who is currently on the 15-day disabled list, was expected to make a return to the Blue Jays' rotation in the near future until he suffered a setback making a rehab start for Class A Dunedin.

The California native threw two innings for Dunedin on Monday and allowed three runs on five hits. He left the game after two innings when he said the pain in his forearm had returned and was immediately shut down.

Morrow had been expected to rejoin the big league club at some point next week but his return date is now uncertain. He will eventually resume bullpen sessions before embarking on another rehab assignment prior to his arrival.

The delay is unfortunate, but a major injury appears to have been avoided and that should bode well for Morrow's second half of the season. He is 2-3 with a 5.63 ERA in 10 starts this year for the Blue Jays.

Lawrie resumes baseball activities

TORONTO -- Blue Jays third baseman Brett Lawrie has resumed baseball activities after being kept out of action for almost a month with a sprained left ankle.

Lawrie hasn't played since May 27, when he sprained his ankle attempting to steal second base. The British Columbia native was placed in a walking boot for several weeks but appears to be making progress in recent days.

"We're not sure yet, but he took some groundballs, took some batting practice, did a little bit of running," Blue Jays manager John Gibbons said when asked about a timeline. "But he's probably still a little ways away."

The Blue Jays are 71 games into their season, but have not had the luxury of using both Lawrie and shortstop Jose Reyes at the same time. Lawrie missed the beginning of the season with a sprained oblique muscle, and Reyes has been out since April 12 with a sprained ankle of his own.

Lawrie is hitting .209 with five homers and 14 RBIs in 37 games this season.
