Astros lineup for Tuesday; Keppinger unavailable

The Astros will try to get back on track Tuesday night against the Mets and Johan Santana, (10-6, 2.89 ERA) who hasn’t allowed an earned run in his previous two starts. He’ll start against Nelson Figueroa (3-1, 3.38 ERA), who is making his first start for the Astros and second this year.

Jeff Keppinger, who left Monday’s game with a sprained left big toe, could have a small fracture in the toe, general manager Ed Wade said. Keppinger had an X-ray and was going to undergo an MRI to further gauge the extent of the injury.

“He got an X-ray done and now they’re going to do an MRI to see what’s going on in there,” Wade said. “There’s a possiblity he’s got a small fracture. Wehther it’s an old fracture or new fracture, they’ll be able to ascertain that once he gets the MRI done.”

Here are the lineups, with Chris Johnson back up to fifth in Keppinger’s absence:
