After the Mets had achieved the first out, a strikeout, in the bottom of the fourth, Alou left his position in left field and moved toward the Mets' dugout near third base. He was met by manager Willie Randolph and trainer Ray Ramirez. They escorted him off the field, but he required no assistance.
Alou hadn't handled a ball in the field or even backed up on a play to that point, and he had grounded out to third base in his lone at-bat in the second inning.
Marlon Anderson replaced Alou in left.
Alou, 41, was assigned to the disabled list until May 2 because of a hernia suffered in Spring Training. He has appeared in 14 games.
