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.

Mike Jacobs graduated from Hilltop High School in Chula Vista[1][2] 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.[3]

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 2003, after a successful year with the Double-A Binghamton Mets, won an award.

In May 2004, 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 2005, 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[4] and played for the Triple-A Colorado Springs Sky Sox. While there, Jacobs was suspended for fifty games after testing positive for HGH.[5] Jacobs was released from the Colorado Rockies on August 18, 2011.

Jacobs made his major league debut with the Mets on August 21, 2005, hitting a three-run pinch-hit home run against Esteban Loaiza of the Washington Nationals in his first ever Major League at-bat.[6] Jacobs rather instantly assumed the position of everyday first baseman and continued to hit, tallying four home runs through three games, during the Mets' 4-game drubbing of the Arizona Diamondbacks. 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.

Jacobs with the Florida Marlins in 2008

In only 30 games and 100 at-bats, Jacobs hit an impressive 11 home runs and 23 RBI. Many people penciled him in as the Mets' first baseman for the 2006 season. However, on November 23, 2005, the Mets traded him and a minor league pitcher, Yusmeiro Petit, to the Florida Marlins in exchange for Carlos Delgado and $7 million.

In 2006 with the Marlins, Jacobs played in 136 games while hitting .262 with 20 home runs and 77 RBI. In 2007, he only played in 114 games, but still improved on his batting average hitting .265 that season including 17 home runs and 54 RBI. In 2008 Jacobs saw increased playing time and had a break out season in power with 32 home runs and 93 RBI but his batting average slipped to .247.

After the 2008 season, Jacobs was traded to the Kansas City Royals for pitcher Leo Núñez.[7] While initially thought to split time at first base with Billy Butler, he was mostly the team's DH due to inconsistent play on the field. Following the season, Jacobs was released by the Royals on December 10.

On October 25, Jacobs was removed from the 40-man roster and sent outright to the Triple-A Reno Aces.[12]

On June 4, 2013, the Arizona Diamondbacks signed Jacobs back to a minor league contract.[15] Jacobs returned to the Triple-A Reno Aces for the 2014 season; he participated in the Triple-A Home Run Derby as well.

On March 26, 2015, it was reported that Jacobs had signed on to return to play for the Guerreros de Oaxaca of the Mexican League.[16] In 111 games he hit .276/.353/.436 with 14 home runs, 83 RBI, and two stolen bases.

Contrary to popular belief, Jacobs is not Jewish. This was apparently not known to the Marlins when, on May 28, 2006, as part of the team's Jewish Heritage Day promotion, they gave Jacobs T-shirts to young fans who attended the game.[19] In reference to this, Jewish sports podcast Menschwarmers refers to non-Jews with Jewish-sounding names as "Mike Jacobs All Stars."[20]
