Cincinnati Hee Seop Choi rejoined the Chicago Cubs and resumed workouts Tuesday, 10 days after a collision at Wrigley Field knocked him unconscious.
He no longer has headaches and no longer has to stay in his apartment and follow his team on television -- something he found unbearable.
"I can't watch," he said. "I'm scared during the tight games."
Choi hadn't done anything physical since June 7, when he and pitcher Kerry Wood chased a popup. They collided and Choi fell hard, slamming his head on the ground.
The 6-foot-5, 240-pound first baseman lay motionless for several minutes as the ballpark went silent. The game was delayed for 17 minutes while Choi was removed in an ambulance.
The fans chanted his name during the ninth inning of a 5-2 victory over the New York Yankees that foiled Roger Clemens' bid for career win No. 300. Choi was released from a hospital a day later.
Sitting in the dugout in a blue "Cubs Spring Training 2003" shirt Tuesday, Choi said his memory had begun to return a day after the collision.
"I remembered the stadium, the pop fly," he said. "I didn't remember the game, just the pop fly and everybody saying, 'Hee Seop Choi.' I thought it was a dream."
Choi, the first Korean-born position player in the majors, has received a lot of cards and letters from fans.
