* Oliver Perez is en route to Arizona but might not be activated immediately. Jerry Manuel said when Perez returns it would be as a situational lefty with Hisanori Takahashi remaining in the rotation.
The Mets would like to unload Perez’s contract in a trade for a pitcher. With the asking price for Roy Oswalt and Dan Haren too high for GM Omar Minaya’s liking, the Mets are concentrating on a middle-tier arm such as Ted Lilly, Brett Myers, Ben Sheets or Jake Westbrook.
For some reason, they won’t give Pat Misch a chance. Misch pitched well for them last year and represented Triple-A Buffalo in that league’s All-Star game.
* We are expected to see Carlos Beltran and Jose Reyes in the lineup tonight at Arizona. It will be the first time in over a year they’ve been on the field together.
* It is anticipated Luis Castillo will be activated for tonight’s game. Ruben Tejada, who played well in the field, but had his problems at the plate, is expected to be optioned to Triple-A Buffalo where he’ll get regular at-bats.
