Martinez (foot) began swinging a bat Friday and manager Brad Ausmus said he is progressing well, Evan Woodbery of MLive.com reports.
Martinez is rehabbing in extended spring training, but continues to make strides towards a full recovery. The veteran slugger sprained a ligament while diving in a Grapefruit League game, delaying the start of his 2017 season and enabling a right-field platoon between Mikie Mahtook and Tyler Collins. Barring any setbacks, expect Martinez to ramp up his rehabilitation within the coming weeks.
