The New York Yankees announced today they have added left-handed pitcher Wilkin De La Rosa and right-handed pitcher Eric Hacker to the 40-man roster. De La Rosa, 23, was 9-4 with a 2.11 ERA (106.2IP, 72H, 35R, 25ER, 44BB, 125K) in 32 combined games (11 starts) with Single-A Charleston and Single-A Tampa in 2008, ranking fifth in the organization in strikeouts. He began the season in the bullpen and was 3-1 with a 2.74 ERA (49.1IP, 15ER) in 21 relief appearances. In his 11 starts, he went 6-3 with a 1.82 ERA (59.1IP, 12ER), limiting opponents to 2ER or less in each start. Signed by the Yankees as a non-drafted free agent in November 2001, De La Rosa was converted to a pitcher in 2007, going 1-0 with a 2.63 ERA in 12 relief appearances with the GCL Yankees in his first action on the mound (24.0IP, 32K). The Dominican Republic native played his first five professional seasons (2002-06) as an outfielder, batting a combined .224 with three home runs and 88RBI in 287 games. Hacker, 25, was 9-6 with a 2.43 ERA (144.1IP, 121H, 47R, 39ER, 37BB, 115K) in 26 combined starts with Single-A Tampa and Double-A Trenton in 2008, ranking second in the organization in ERA. He limited opponents to three runs or less in all but one start, including a stretch of four straight starts without giving up an earned run from 4/8-24 w/ Tampa (27.0IP, 7H, 2R, 2BB, 18K). On 4/8 vs. Dunedin (TOR), in his second start of the season (w/ Tampa), he threw 7.0 no-hit innings but did not record a decision. Hacker went 2-0 with a 1.54 ERA in two postseason starts for the Double-A champion Trenton Thunder, recording the win in Game 1 of the Eastern League Division Series and Game 1 of the Championship Series. In six minor league seasons (2002-08), Hacker owns a 30-15 record with a 2.70 ERA in 75 games (67 starts). He was selected by the Yankees in the 23rd round of the 2002 First-Year Player Draft.
