Nakamura was the starting DH and batted 4th in his rehab game today. It seems he hit a 3-run homer in his first at bat, walked in his second at bat, and struck out in his third at bat.
As of yesterday, Takeya Nakamura was scheduled to play in a rehab game against Ni-gun Shonan today (start time 13:00). Assuming he's feeling fine after starting as a DH, he could be moved over to third tomorrow. And if his rehab goes well moving forward, there's a good chance he could return to the active roster before the end of the month.
