Walker went 3-for-5 with a two-run home run and a second run scored in Friday's 7-6 extra-inning loss to the Phillies.
The young slugger took Jesus Luzardo deep in the sixth inning to briefly give the Cardinals a 4-3 lead in a wild, back-and-forth affair. Walker has homered in three straight games while extending a hit streak to seven games, a blistering stretch in which he's batting .467 (14-for-30). That surge has pushed his slash line on the season up to .291/.350/.513 with 28 doubles, 27 home runs, 17 steals, 81 runs and an MLB-leading 96 RBI, tied with the Reds' Sal Stewart.
