The Phillies have a glut of starting pitching and a dearth of relief. Mick Abel will fill Walker’s starting spot Thursday in Toronto. The Phillies have four capable starters, plus the injured Aaron Nola, plus Abel, plus Andrew Painter once July arrives. That leaves no room for Walker.

The Phillies intend to recall Mick Abel to start Thursday against the Blue Jays. Bryce Harper is also expected to return to the lineup on Tuesday.

Philadelphia Phillies right-hander Taijuan Walker is being shifted from the starting rotation to the bullpen as the team retools its pitching staff.
