Last season, Reyes was hitting .271 during mid-August, but had just one hit in his final 26 at bats.

Argenis Reyes will start at second base and bat eighth tonight instead of Luis Castillo.
Jerry Manuel, speaking with reporters about Castillo prior to tonight’s game, said:

“I wanted to give him a break from what he’s going through.  He’s not swinging the best that he has…We’ll need him at some point…I don’t know if it’s a one-day [...]
