Jordan Walker

Walker's offseason swing evaluation at Driveline revealed that his back hip was collapsing, causing him to drift forward and sap his power production last season. He said he's feeling more optimistic after working through a series of drills designed to keep his hips back and allow him to drive the baseball again. It's no secret the 23-year-old former top prospect hasn't lived up to the astronomical hype yet, but the underlying metrics continue to tease big-time potential. His 92.3 mph average exit velocity and 78.1 mph bat speed last year graded out as elite-level tools -- the kind you can't fake. He's made mechanical tweaks in previous offseasons, so it's understandable if fantasy managers remain in wait-and-see mode. Still, the raw ingredients are here for a legitimate breakout if this latest adjustment finally unlocks his potential.
