Hideaki Wakui started playing catch today (at a distance of about 20 meters). The Lions shut Wakui down after taking him off the active roster on the 6th with discomfort in his right elbow.
Takayuki Kishi may be ready to rejoin the Ichi-gun roster soon -- he worked out (like playing catch and running) with the Ichi-gun pitchers at Seibu 2 Stadium earlier today. Daily Sports mentions Kishi could get a start during the Softbank Hawks series (5/13 - 5/15).
Daisuke Kusano will take over the roster spot that opened up when Randy Ruiz was removed from the active roster today.
Satoshi Komatsu will likely be activated tomorrow. For now, it seems Akinobu Okada will be using him as a long reliever. Komatsu went 2-2 with a 2.87 ERA in 7 Ni-gun games (47 IP, 39 H, 3 HR, 6 BB, 2 HBP, 24 SO).
