Phillies ace Zack Wheeler diagnosed with blood clot in right arm, placed on 15-day IL

The Philadelphia Phillies placed ace Zack Wheeler on the 15-day injured list Saturday with a blood clot in his right arm.

WASHINGTON — The Philadelphia Phillies placed ace Zack Wheeler on the 15-day injured list Saturday with a blood clot in his right arm.

Dave Dombrowski, the president of baseball operations for the Phillies, said after a 2-0 loss at Washington that Wheeler had been diagnosed with a "right upper extremity blood clot."

"There's not a lot that we can say on it at this time," said Dombrowski, who commended doctors for finding the clot. "It could have been a much more trying situation than it is."

Phillies head athletic trainer Paul Buchheit said Wheeler had been feeling better after some right shoulder soreness caused him to push back a start earlier this month. But that changed Friday.

"He felt a little heaviness," Buchheit said. "So, the doctors here were great in helping to diagnose and expedite that diagnosis this morning."
