Minutes after the Phillies’ 2-0 loss to Washington, Dombrowski announced that Zack Wheeler is being placed on the 15-day injured list with a “right upper extremity blood clot.” The Phillies’ president of baseball operations was joined by head athletic trainer Paul Buchheit.

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

Dombrowski told reporters on Saturday evening that the Phillies are placing Wheeler on the 15-day IL with a blood clot in his right shoulder, which is his throwing arm. As ESPN's Jeff Passan reported, the timeline for Wheeler's return is "unclear."
