Hiroki Kuroda worked out at Mazda Stadium on May 12. He ran short dashes before he played some catch and maxed out the distance at about thirty meters. It was the first time he threw the ball since his last outing on May 7 against Yokohama at Mazda Stadium.
Kuroda’s day also included running (stairs, along the outfield fence) and time in the weight room.
