NEW YORK -- The Yankees finalized their Opening Day roster on Saturday, selecting infielder Ramiro Pena as the club's 25th man over former American League Rookie of the Year Angel Berroa.
The announcement was made after the Yankees' 10-1 Spring Training victory over the Chicago Cubs at the new Yankee Stadium, with the 23-year-old Pena beating out the 31-year-old Berroa to serve as New York's utility infielder beginning the season.
Despite having not played above Double-A Trenton, Pena opened eyes in camp when Derek Jeter left the club for the World Baseball Classic, showcasing a slick glove and a developing bat. Pena batted .277 (18-for-65) with two doubles, a triple and seven RBIs in 30 Spring Training games for New York.
Berroa, who edged Hideki Matsui as the AL's top rookie in 2003 as a member of the Royals, came up short in his bid to make the big league club, despite having a stronger offensive spring. Berroa was in camp as a non-roster invitee and hit .371 (23-for-62) with eight doubles, two home runs and 11 RBIs in 29 spring games.
In order to make room on the 40-man roster, the Yankees designated right-hander Dan Giese for assignment. Giese was 0-1 with a 6.48 ERA in nine Grapefruit League games.
The Yankees also officially placed third baseman Alex Rodriguez on the 15-day disabled list with a right hip labral tear, retroactive to March 27. Rodriguez continues to rehab in Colorado and is expected back in New York's lineup by May 15.
