Sparky Anderson was born in Bridgewater, South Dakota. 

J. J. Putz was drafted by Minnesota in the seventeenth round in 1998, but did not sign.

Left-hander Brian Matthew Duensing has pitched for the Twins since 2009.  He was born in Marysville, Kansas, went to high school in Omaha, and attended the University of Nebraska.  He was drafted by the Twins in 2005.  He pitched well in his first few years in the minors and had a fine season in 2007, when he went a combined 15-6, 3.07 with a WHIP of 1.19 in nine starts at AA New Britain and 19 starts in AAA Rochester.  He pitched for the U. S. Olympic team in Beijing in 2008.    He also pitched in Rochester in 2008 and 2009 and seemed to be getting worse, posting higher ERAs and WHIPs each season.  Despite that, however, he made his major league debut in 2009, making one start in April and then being brought up in early July and staying the rest of the season.  He pitched better than one might have expected, going 5-2, 3.64 with a WHIP of 1.37 in 84 innings.  He made twenty-four appearances, nine of them starts.  He started 2010 in the Twins bullpen but again ended it as a starter, moving into the rotation in late July.  In 2011 he was in the rotation all season (other than when injured), and it did not go well.  So far in his major league career, Brian Duensing is 24-19, 3.97, 1.37 WHIP in 376.1 innings.  He has made 109 appearances, 50 of them starts.  His numbers are significantly better as a reliever than as a starter, although this was not the case before last season.  It is projected that Brian Duensing will be in the Twins' bullpen in 2012.
