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 Triple-A
Colorado Springs Sky Sox. While there, Jacobs was suspended for fifty games after testing positive for HGH. Jacobs was released from the Colorado Rockies on August 18, 2011.
New York Mets Jacobs made his major league debut with the Mets on August 21, , hitting a three-run
pinch-hit home run against
Esteban Loaiza of the
Washington Nationals in his first ever Major League at-bat. 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.
Florida Marlins 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 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.
Kansas City Royals After the season, Jacobs was traded to the Kansas City Royals for pitcher
Leo Núñez. 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.
New York Mets (second stint) On February 10, 2010, the Mets signed Mike Jacobs to a minor league contract. He was selected as the Mets' opening day first baseman after
