Michael James Jacobs (born October 30, 1980) is an American former professional baseball first baseman. He played in Major League Baseball (MLB) for the New York Mets, Florida Marlins, Kansas City Royals, and Arizona Diamondbacks. Career Minor Leagues Mike Jacobs graduated from Hilltop High School in Chula Vista and spent one season at Grossmont College in El Cajon, California before being selected by the New York Mets in the 38th round of the 1999 Major League Baseball Draft. Originally signed as a catcher, Jacobs batted .333 with four home runs and 30 runs batted in his first professional season with the Gulf Coast League Mets. He quickly blossomed into a solid power-hitting prospect and, in , after a successful year with the Double-A Binghamton Mets, won an award. In May , while playing for the Triple-A Norfolk Tides, Jacobs suffered an arm injury and underwent surgery for a torn labrum, which ended his season prematurely. Because of his injury and mediocre defensive skills behind the plate, when Jacobs returned to Binghamton in , he spent much of the season learning to play first base. He batted .321 with 25 home runs and 93 RBIs while learning his new position and going on to win the MVP award. On December 18, 2010, Jacobs was signed by the Colorado Rockies and played for the affiliate triple-A team in Colorado Springs, Colorado. While there, Jacobs was suspended for fifty games after testing positive for HGH. Jacobs was released from the Colorado Rockies on August 18, 2011.

During this stretch the Mets were able to pull within a half-game of the National League Wild Card lead, but faded quickly, dropping two straight games at home to the Philadelphia Phillies and promptly falling out of the race. Jacobs continued to play well, increasing his stock as a trade chip by slugging a monstrous .710 in his five weeks as a major leaguer.
