Jordan Walker has been everything the St. Louis Cardinals wanted and more in his rookie season. The outfielder has provided a steady bat in their lineup, flashing elite power with his intimidating, 6-foot-6, 245-pound frame. That was apparent Tuesday against the Atlanta Braves, when Walker crushed a ball 413 feet over the center field fence in the fourth inning. The shot pushed him ahead of Hall-of-Famer Rogers Hornsby for most home runs in Club history by a player before the age of 22.
