Phil Hughes figures if he works an exhibition game by March 14 there will be enough time for him to make his first regular-season start.

“That would give me four starts, which is enough,’’ said Hughes, who hasn’t thrown an inning yet because of a bulging disk in his upper back, suffered almost two weeks ago when he was covering first base in a fielding drill.

Hughes hasn’t touched a baseball since the injury. He said if he doesn’t have a setback, tomorrow he will resume light baseball activities.

“I can ramp it up from there,’’ Hughes said.

He already increased his daily workouts Friday. After working in the pool, Hughes performed back-stretching exercises with large rubber bands outdoors.

“That would be a good sign on Sunday,’’ manager Joe Girardi said of the possibility Hughes will toss.

* Hiroki Kuroda’s first spring outing contained good and bad segments, according to the right-handed starter, who is expected to fall in behind ace CC Sabathia in the rotation.

“There were a few pitches that were good and a few that were not,’’ Kuroda said of the 41-pitch effort that covered 1 2/3 innings. “The main thing is to throw strikes, put the ball in the zone and work on breaking balls that are not there yet. Right now I am working on the curveballs. They weren’t really good today.’’

Kuroda gave up three hits and four runs (one earned).

* Yesterday’s sloppy 10-5 loss to the Phillies at George M. Steinbrenner Field was the Yankees’ seventh straight and dropped their record to 1-7.
