Reality check: Ix-nay on Nixy

TORONTO -- The Yankees sent Jayson Nix back to New York for an MRI this morning after the utility infielder complained of a sore left hip flexor suffered while playing third base in Thursday night's game against the Blue Jays.

If Nix is out for any length of time, a possibility raised by Joe Girardi, it means the Yankees have no backup for Robinson Cano, who narrowly escaped serious injury when he was hit by a pitch on the left hand Friday night.

"There's a possibility we may not have him for a while," Girardi said of Nix, a sure-handed infielder who was batting .243 with four homers and 18 RBI. "And that's why Nuney becomes all the more important."

"Nuney," of course, is Eduardo Nuñez, the error-prone infielder who had not played since Sept. 23, when he booted a grounder at shortstop to allow the winning run to score in a game against the Oakland Athletics.

Nuñez is in today's lineup, playing shortstop as Derek Jeter gets a DH day to spare him from the artificial turf at the Rogers Centre, and although Girardi said he would prefer not to use Nuñez at any other position, he would become the emergency second baseman if anything were to happen to Cano.

"He becomes our main backup infielder now," Girardi said.
