WASHINGTON – The Mets were concerned enough about Omar Quintanilla’s injured finger that manager Terry Collins waited until just before noon to announce the lineup for Thursday’s matinee against the Nationals.

Quintanilla was in the lineup. So was Jason Bay for the first time since his return from the disabled list.

Then, about 25 minutes later, came a new lineup. Bay was scratched with the flu and Scott Hairston started in leftfield against Chien-Ming Wang.

Quintanilla injured the index finger on his left hand while attempting to make a diving catch on a pop fly on Wednesday. Jordany Valdespin, who made two errors in the 10th inning on Tuesday, would have started at shortstop if Quintanilla had not.
