After spending seven seasons in the Mets minor league system where he was converted from a catcher to a first baseman Mike Jacobs made his major league debut with the Mets on August 21, 2005. In his first at bat Jacobs hit a pinch hit three run home run. In doing so he became the 4th player in Mets history to hit a home run in his first major league at bat.
Two days later Jacobs hit his second home run and followed that up with a two home run performance on August 24. In his first four games, he had hit four home runs. From that point on Jacobs assumed the everyday first base position. In 30 games for the Mets he hit .310 with 11 home runs and 23 RBIs.
It appeared the Mets had found their first baseman of the future. But when the Florida Marlins made All-Star slugger Carlos Delgado available, the Mets included Jacobs in a trade to acquire his services.
After three seasons with the Florida Marlins and one with the Kansas City Royals Jacobs returned to the Mets in 2010. The Mets signed him to a minor league contract and he made the team out of Spring Training and was the Opening Day first baseman. But his second stint with the Mets was not as successful. He appeared in just seven games and hit just .208 with a home run and two RBIs. The Mets sent Jacobs down to the minors where he played for their Triple A affiliate the Buffalo Bisons before being traded to the Toronto Blue Jays in July.
In 37 games for the Mets Jacobs hit .290 with 12 home runs and 25 RBIs.
While with the Mets Jacobs wore number 27 in 2005 and 35 in 2010.
Mike Jacobs also played for the following teams:
Florida Marlins – 2006-2008
Kansas City Royals – 2009
Arizona Diamondbacks – 2012
