Bob Zuk was a long-time scout who was responsible for signing, among others, Reggie Jackson, Willie Stargell, and Gary Carter.

Terry Cooney was an American League umpire from 1975-1992.

Left-hander Pedro Michel Hernandez has not played for the Twins yet, but joined their farm system in late July of 2012.  He was born in Barquimsimeto, Venezuela and signed with San Diego as a free agent in 2006.  He did very well in rookie ball but struggled in his first two tries at Class A.  He took a substantial step forward in 2011, pitching well in both A and AA, although he struggled in four AAA starts.  He was traded to the White Sox after the 2011 season in a deal for Carlos Quentin.  He started very well in AA in 2012 and also did well in three AAA appearances.  He made what one presumes was an emergency start for the White Sox on July 18 in Boston, allowing eight runs on twelve hits in four innings.  He was traded to Minnesota with Eduardo Escobar on July 28 for Francisco Liriano.  The Twins sent him to Rochester, where he struggled in four starts, going 0-2, 5.19, 5.00 WHIP.  He began 2013 in Rochester but was promoted to Minnesota early in the season.  He has made one start so far, a start which was not great but not awful.  His AAA numbers are not very impressive, but he's only twenty-four today.  If he can take another step forward this season, the Twins could have something.
