Hyeseong Kim worked with Dodgers coaches all offseason to rebuild his swing.

According to California Post’s Jack Harris, “They focused on Kim’s legs, trying to get [him] to use the ground to generate more power and stability. Then, they honed in on the alignment of his torso and back, making subtle adjustments aimed at keeping Kim squared up to the ball longer.” Kim struggled in his first MLB season last year, finishing with a .280 batting average, but a .699 OPS and a 30.6 percent strikeout rate. If he’s able to handle breaking balls better this season, Kim could start at second base until Tommy Edman (ankle) returns.
