Walker will re-enter the Phillies' starting rotation Tuesday against the Giants, Matt Gelb of The Athletic reports.

EDGE Analysis

The veteran right-hander worked as a starter for Philly early in the season but has spent the past month pitching out of the bullpen, and he's been decent in both roles with a 3.64 ERA, 1.33 WHIP and 46:22 K:BB across 54.1 innings overall. Walker would likely only be able to cover about four innings while filling the spot vacated by Mick Abel, who was optioned to Triple-A Lehigh Valley on Friday, and he isn't guaranteed to stick in the rotation after the All-Star break.
