Philadelphia right-hander Taijuan Walker (5-8, 4.17) will start Friday, with Walker Buehler also expected to pitch multiple innings. Phillies DH Kyle Schwarber leads the NL with 53 homers and leads MLB with 128 RBIs. He yielded four runs in a 5-4 loss to the D-backs last year, his only career appearance against them. He is 0-1 with a 4.15 ERA in three starts against the Phillies.
