The Yankees’ rotation is one Triple-A start away from being whole for the first time this year.

After what he described as his best outing so far, Phil Hughes is scheduled to pitch for Scranton/Wilkes-Barre at home Saturday night against Pawtucket.

If Hughes, who was targeted as the No. 4 starter before a bulging disk in the upper back shelved him early in camp, comes through Saturday night’s assignment without a problem he will join the Yankees in Cleveland and bump David Phelps or Ivan Nova to the bullpen or SWB.

“[Monday] was miles ahead of where I was,’’ said Hughes, who threw the equivalent of seven innings against Single-A Tampa at the Tampa complex. “The velocity was good the first two times, and [yeserday] it improved.’’

According to Hughes, his location was better than it had been. Though the disk problem vanished weeks ago, Hughes started the season on the disabled list to build arm strength and get sharper.

“There are no issues, everything is fine,’’ Hughes said.

The early favorite to be replaced is Phelps for several reasons.

One, he will start Saturday against the Tigers in Detroit and Nova goes the night before. With Hughes pitching Saturday night, he would slide into the April 11 game in Cleveland, which would be Phelps’ next scheduled outing.

Two, Phelps has more experience working in relief than Nova. Phelps threw 1 1/3 innings in Monday’s Opening Day 8-2 loss to the Red Sox at Yankee Stadium.
