Taijuan Walker News: Piggyback with Buehler on Friday

Walker will be piggybacked by Walker Buehler on Friday in Arizona, Matt Gelb of The Athletic reports.

Walker will get the ball first in the tandem start. The Phillies initially operated with a six-man rotation when Buehler was added to the mix, but they're realigning things in order to set up Cristopher Sanchez for the first game of the postseason. Walker has struggled lately, collecting a 7.20 ERA and 14:9 K:BB over 25 innings covering his last five starts.
