 Biographical Information
The brother of All-Star Joe Mauer and minor leaguer Bill Mauer and great-nephew of John Mauer Sr., infielder Jake Mauer was selected by the Minnesota Twins in the 23rd round of the 2001 amateur draft (the same year Joe was taken with the first overall pick).
The older Mauer had hit .391 in college and was a two-time NCAA Division III All-American. He set school records in hits (243) and runs (181).
Mauer played five seasons in the Twins farm system, hitting .265 in 365 games. The Mauer brothers debuted with the same team, the Elizabethton Twins. Jake hit .155/.310/.172, a far cry from Joe's .400/.492/.491 line, while backing up at third base. In 2002, Jake and Joe again were teammates all year, this time with the Quad City River Bandits. Jake batted .226/.334/.262 in 84 games, fielding a crisp .993 at second base, where he was the starter. Had he qualified, he would have led Midwest League second basemen in fielding percentage - Ruben Gotay was the official leader at .973.
The brothers kept pace for part of one more year, 2003, when they played for the Fort Myers Miracle before Joe was promoted. The gap narrowed further, with Joe only having a 56-point edge in average and 43 points in OBP. Jake batted .279/.352/.303 in 109 games, now primarily at shortstop, where he fielded .983. He again would have had the best fielding percentage for his position and league had he qualified.
In 2004, Jake hit .258/.311/.325 in 101 games for the New Britain Rock Cats as the main third baseman for the AA team. He bounced around in an injury plagued final season in 2005 - 2 for 6 for the GCL Twins, .319/.365/.362 in 19 games for Fort Myers and .250/.314/.313 in 25 games for New Britain.
Mauer was a coach for the GCL Twins in 2006-2007. In 2008, he took over as the team's manager, then moved to the Fort Myers Miracle in 2010. In 2013, he was named manager of the Cedar Rapids Kernels in the Midwest League.
