Manager Rob Thomson disclosed that Walker underwent tests in Clearwater, with the Phillies anticipating results by Sunday. However, Walker's absence from Monday's Grapefruit League finale seems inevitable, likely leading to his placement on the injured list as the season begins.
In addition to Walker's setback, reliever Orion Kerkering is also slated to start on the injured list due to a weeklong bout with the flu, which hindered his progress during camp. Should Walker indeed join him on the sidelines, right-hander Spencer Turnbull stands poised to step into the rotation. Turnbull's scheduled relief appearance on Saturday morphed into a starting role, where he impressively held the Yankees to three hits over three scoreless innings.
Walker's road to recovery has been beset with challenges, including earlier discomfort in his right knee during spring training. His recent outing against the Orioles, where he conceded seven runs in 2 2/3 innings, further underscored his struggles.
Beyond the starting rotation, Walker's potential absence would disrupt the bullpen dynamic. With Turnbull transitioning and Kerkering playing catch-up, the Phillies must now evaluate candidates for three open bullpen spots between Luis Ortiz, Yunior Marte, Connor Brogdon, José Ruiz, and Andrew Bellatti.
The Phillies will play the Blue Jays in Clearwater on Sunday. First pitch is scheduled for 1:05 p.m.
