PHILADELPHIA - Phillies pitcher Zack Wheeler had a successful thrombolysis procedure to remove a blood clot in his right upper extremity by Dr. Paul DiMuzio at Thomas Jefferson Hospital on Monday, the Phillies announced. The club said further treatment and a subsequent timeline of recovery will be determined.

PHILADELPHIA — Before he launched a 440-foot homer that he followed with a 448-foot homer, Bryce Harper smacked a slider to dead center. He missed the barrel. He knew it and looked disgusted. He jogged to first base as Julio Rodríguez caught the fly ball, then clapped his hands a few times. “Just missed it,” Harper said.

The Birds won it all after the MVP favorite went down. Wheeler is the best, but the Phillies, like the 2017 Eagles, were built to withstand injuries.

Philadelphia's starting pitchers combined for 34 strikeouts while their team collected 48 hits across three wins over the Seattle Mariners.
