"Jason Bay really hasn't hit all season and now he discovered he couldn't run. So the Mets' left fielder was lifted last night in fourth inning of the Mets' 6-5 come-from-behind victory in 10 innings with what the team called a tight right hamstring.

"It's just been there, and it's something we've kind of been fighting," said Bay, who indicated his latest ailment affects "kind of the whole right leg" after he landed awkwardly on an infield hit Saturday.

Bay told manager manager Terry Collins about it and felt he could play through it with a little caution. Then he grounded out to short and later chased a foul fly down the left field line. Something wasn't right in the left fielder, who said his availability for today's game will be a wait-and-see affair.

"Terry was aware of it," Bay said. "I kind of felt it was OK if I was jogging. I hit that ground ball to short and my first couple [of] steps, I could feel it. I kind of slowed down but there was something that kind of prevented me from really going and then there was a ball down the line my first couple steps again your first instinct is to go real quick, but I could feel it immediately. Not bad, but enough that I'm a little concerned that if I keep going at that pace something bad might happen."

The hamstring doesn't seem like it will be a long-term problem, but then neither did Jose Reyes' left hamstring strain on July 2, which put the Mets' sparkplug on the disabled list.

Bay said everyone decided to be "pro-active rather than reactive" regarding the latest twinge in his leg. With a 12:10 start today, it might make sense to sit Bay."
