St. Louis Cardinals rookie Jordan Walker had himself a day at the plate in the 5-4 win over the San Diego Padres. The outfielder's plate discipline was on full display as he collected his first career four-hit game. The 21-year-old began his day with single to left field in the second inning. He followed up with a no-doubt, three-run shot in the fourth inning to tie the game at three. Still not done, the first-year player would rack up a double in the sixth and single in the eighth. Walker is the youngest Cardinals player with four hits in a single game since 1972.
