Taijuan Walker allowed one run and two hits over two innings Thursday against the Nationals.

Walker gave up two hits and a run in a 20-pitch first. In the second, he allowed a single with two outs, only to pick off Seaver King at first afterwards. Walker is almost certainly going to open up in the Phillies’ rotation with Zack Wheeler down. The question is whether he’ll perform well enough to hang on to the fifth spot once Wheeler is back.
