Could Robertson go four innings?

Joe Girardi will have a short leash on A.J. Burnett in Game 4. If A.J. gets in trouble early, then the Yankees could turn to Phil Hughes as the man to try to get them though those middle innings.

But with desperate times calling for desperate moves, Girardi could -- and probably should -- turn to David Robertson early. Could Robertson go three or four innings? Doesn't seem impossible.

During the season, Robertson's longest outing was two innings. He only did that once on Sept. 3, in a save, against the Blue Jays. He pitched 1 2/3 innings on two occasions. Six times, he recorded four outs in an appearance.

The rest of his outings were one inning or less.

He has been arguably the Yankees' best pitcher this season. He could definitely go two innings in Game 4, but could he go three or even four?
