Alfredo Aceves Martínez (born December 8, 1982, in San Luis Río Colorado, Sonora, Mexico) is a Major League Baseball pitcher who is currently a free agent. He uses a fastball, which can reach the mid 90s, a curveball, a changeup, and a cut fastball. He is known for his control and his ability to throw any pitch in any count.
Aceves was signed by the Toronto Blue Jays as an amateur free agent in Template:By. He made ten starts in the Dominican Summer League that year. However, Aceves felt isolated, and when the Blue Jays assigned him to stay in the DSL for Template:By, Aceves stayed in Mexico, and his contract was purchased by the Yucatán Leones of the Mexican League. Aceves pitched for Yucatán and Sultanes de Monterrey for the next six seasons.
Yankees scout Lee Sigman followed Aceves in the Mexican League, feeling he could achieve similar success as Teddy Higuera, who Sigman had signed for the Milwaukee Brewers. Feeling that he had developed well in the Mexican League, the Yankees purchased Aceves, along with other players, for $450,000 during the 2007-08 offseason. He began Template:By with the Single-A Advanced Tampa Yankees. He was quickly promoted to the Double-A Trenton Thunder and Triple-A Scranton/Wilkes-Barre Yankees. He was named Eastern League pitcher of the week for the week ending May 25, 2008.
After going a combined 8-6 with a 2.62 ERA on the three Yankee farm teams, Aceves was called up to the Yankees on August 28, Template:Mlby. On August 31, Aceves made his Yankee and major league debut, becoming the 106th major-league player to have been born in México, pitching two scoreless innings in relief.
After pitching effectively through his first few relief appearances, Aceves was moved to the rotation in replacement of Darrell Rasner. In his first career start, he pitched seven innings of one-run ball with two strikeouts against the Los Angeles Angels of Anaheim, earning the win.
Due to his ability to pitch effectively in any situation, Aceves has drawn comparisons to former Yankee reliever and spot starter Ramiro Mendoza. Along with Phil Coke, Phil Hughes and Mariano Rivera, Aceves was a key member of the 2009 New York Yankees Season out of the bullpen. In the Game 3 of the 2009 American League Championship Series he was called to relieve David Robertson but he served up a game-winning hit to Jeff Mathis and the Angels defeated the Yankees, 5-4.
Aceves made ten relief appearances in 2010 before succumbing to a strained lower back that ended his season. He suffered a broken collarbone in an offseason bicycle accident. He was non-tendered after the season.
Aceves' father, Alfredo Aceves, was a first baseman in the Mexican League and his older brother, Jonathan Aceves, was a catcher in the Chicago White Sox organization, currently playing for the Saraperos de Saltillo of the Mexican League.
Aceves wears #91 to honor Dennis Rodman, whom Aceves admires for his antics and championships. He is one of three players in Yankees history to wear a number in the 90's, with Charlie Keller and Brian Bruney each wearing #99.
