That distinction may fall to Triple-A righthanders David Phelps or Adam Warren, who along with Andrew Brackman, D.J. Mitchell and Hector Noesi will form the rotation for Scranton/Wilkes-Barre.
The 23-year-old Warren went from North Carolina senior in 2009 to Double-A Trenton last season, when he struck out 126 in 135 innings and went 11-7, 2.59 in 25 starts.
"He got experience at the college level and has moved quickly," farm director Mark Newman said of the 6-foot-2, 215-pounder, who was selected in the fourth round of the 2009 draft.
Warren uses a fastball that Newman said sits at 93-94 mph and touches 96. "He can command the fastball and is sneaky quick," Newman said. "When you have deception plus velocity that's a pretty good combo."
A 14th-round round pick in 2008 out of Notre Dame, Phelps is 6-foot-3, 190-pounds and is a bit more advanced than Warren, based on working a dozen games last year Scranton.
"His fastball has sink and he is a four-pitch guy," Newman said of the Phelps, who went a combined 10-2, 2.50 last year with 141 strikeouts in 159 innings. "He is highly competitive."
Of the group, Brackman has the highest ceiling. A strong second half last year at Trenton led to the Yankees picking up a $1 million option on the 6-foot-11 righthander.
Noesi, a 24-year-old righty who was late reporting to spring training because of visa problems in the Dominican Republic, zoomed through three levels to finish 2010 in Triple-A.
"He is a big-time strike thrower," Newman said. "He needs to command the ball in the strike zone better. His arsenal is good enough."
• Banuelos went home to Mexico for a family issue late in minor league spring training camp, setting him back to start fifth in the Trenton rotation.
• The Yankees claimed Braves lefthander Jose Ortegano on waivers. The 23-year-old struggled in Triple-A last year (6.20 ERA, 1.61 WHIP in 20 starts) but has a quality sinker/changeup mix.
