Walker will work in bulk relief behind an opener during his next turn through the rotation Wednesday against the Cubs, Matt Gelb of The Athletic reports. The veteran right-hander has surrendered 19 earned runs across 18.1 frames in his first four starts of the season, so the Phillies will attempt to limit his exposure to the top of Chicago's lineup Wednesday. Regardless of his role, Walker will have minimal streaming appeal while going up against a Cubs offense that is averaging more than eight runs scored over the past six games. The Phillies are expected to get Zack Wheeler (shoulder) back from the injured list later next week, so Walker may not be in line for any starts or planned bulk-relief appearances for a while after Wednesday's outing.
Walker (1-3) took the loss Friday as the Phillies were routed 9-0 by Atlanta, coughing up seven runs on seven hits and three walks over four innings. He struck out four. The right-hander served up homers to Austin Riley in the second inning and Dominic Smith in the third, the second time in four starts that Walker has been taken deep multiple times. It's been a brutal beginning to the year for the 33-year-old, and he carries a 9.16 ERA, 2.04 WHIP and 16:10 K:BB through 18.2 innings. Zack Wheeler (shoulder) will make what could be his final rehab start Sunday, but that schedule would allow Walker to get one more turn through the rotation on the road next week against the Cubs before being replaced.
Walker (1-2) picked up the win in Saturday's 4-3 victory over the Diamondbacks, allowing two runs on four hits and two walks over five innings. He struck out six. Arizona jumped on the right-hander for two runs in the top of the first inning, including a leadoff homer by Ketel Marte, but Walker settled in and gave the Phillies a chance to respond. Zack Wheeler (shoulder) is still getting stretched out on a rehab assignment, so Walker should make at least one more start before things begin to get crowded in the rotation. He'll take a 7.36 ERA, 1.91 WHIP and 12:7 K:BB through 14.2 innings into his next outing, which lines up to come at home next weekend against Atlanta.
