Both off to hot starts this season, the Yankees have decided to promote a pair of power-slugging infielders down in the minor leagues, sending catcher/outfielder Peter O'Brien from High-A Tampa to Double-A Trenton. Making room for him in Trenton, first baseman Kyle Roller was promoted to Triple-A Scranton.

O'Brien was showing a great bat down in the Florida State League early in the season, hitting .321 with 10 homeruns and 19 RBIs.

I didn't think that a promotion, though deserved, would come this soon for O'Brien, being a below-average catcher with the Trenton Thunder already having top prospect Gary Sanchez behind the dish for them.

Moving Roller, who was leading the Eastern League in homeruns with 9, up to Triple-A, I suppose, opens up a place for O'Brien to play, in first base. The Yankees tried him out at third base and right field last season in Tampa, but Yankees VP of Baseball Ops Mark Newman called third base a "last option" for O'Brien, so it would seems like first base and right field are the most likely options for him to reach the big leagues.

Roller, who only hit 17 last season in 124 games, already has 9 this season. The Yankees selected him in the 8th round of the 2010 draft, and has slowly been working his way through the system. If the Yankees absolutely need first base help at some point, Roller might be a guy to look from down in the minors.
