Alex Cora filled in for Reyes and left, last night's game, in the third inning with a sprained thumb.
Fernando Tatis filled in for the rest of the night, but hasn't played short stop regularly since 1998, and doesn't appear to have the range for the position.
The Mets back-up plan is Ramon Martinez, the 36 year old, right handed, infielder is only seven games back from hernia surgery. Martinez is hitting .290 in Buffalo since coming off the disabled list.
Last year, Martinez was called up, in September and played seven games at second base, in which he hit .250.
Martinez is a ten year veteran who can play any infield position and is a lifetime .264 hitter. He lost most of 2006-2007 to wrist injuries which is how he landed in the minor leagues.
