Yorke added significant muscle over the offseason and also tweaked his swing in order to create more loft, Colin Beazley of the Pittsburgh Post-Gazette reports.
Yorke worked out for three-and-a-half hours per day on a near-daily basis over the offseason to remake his body and add strength. It's already shown up in his spring training results, too, as he's gone 4-for-11 at the plate in the early going. During Tuesday's game versus the Red Sox, he hit two balls in excess of 110 mph. Yorke is competing for a utility role with the Pirates.
