The Yakult Swallows have decided to sign Naoya Okamoto after two days of tryouts. They are expected to make an announcement within the next couple of days.
Okamoto tossed a bullpen session on Saturday and tossed situational BP on Sunday. During his BP outing, Okamoto faced 6 batters, topped out at 145km/h, and appeared to have a rough time getting lefties out (he gave up a homer to Shinichi Takeuchi and a single to Atsushi Fujimoto) but still impressed the coaches enough with the movement on his pitches.
UPDATE 7/26 @ 6:05pm - The Swallows officially announced today that they signed Okamoto.
UPDATE 7/28 @ 12:45am - Okamoto's contract is apparently worth 7M yen. He was also assigned the number 46. A press conference formally announcing the agreement was made at Jingu Stadium on Wednesday (7/27).
