Ace will be re-evaluated after two weeks

OAKLAND, Calif. -- Toronto right-hander Roy Halladay was
placed on the 15-day disabled list Tuesday, and the Blue Jays
activated outfielder Frank Catalanotto to fill his roster spot.

Halladay, last season's AL Cy Young Award winner, has a tired
right shoulder that won't improve without rest. He is 7-7 with
a 4.35 ERA this season.

He will be re-evaluated after two weeks of rehabilitation,
probably at the Blue Jays' spring training complex in Dunedin, Fla.

"In layman's terms, he's got a fatigued shoulder," general manager J.P. Ricciardi said. "No tears. Nothing surgically that needs to be done. The MRI results were negative."

Catalanotto went on the disabled list June 26 with a right groin
injury. He's hitting .327 with one homer and 23 RBIs this season.

The Blue Jays also signed left-hander Zachary Jackson, their
first-round draft pick. Jackson went 10-7 with a 3.58 ERA for Texas
A&M this season. He is expected to report to Class-A Auburn of the
New York-Penn League on Wednesday.
