Sean Marshall was drafted by the Cubs in 2003 and debuted for them in 2006. He spent two years as a starter then transitioned into a very successful reliever. He was traded to the Reds after the 2011 season and has kicked some serious arse as an 8th inning reliever. He was injured the majority of 2014, but he was better off not being a part of this year's dumpster fire. Signed is a 2013 Topps #251.
Bill Bray was drafted in the first round by the Expos in 2004 and debuted for them (after they moved to Washington) in 2006. He was traded to the Reds mid-year and would stay in Cincy through 2012 as a reliever, including a 79-game season in 2011. Signed is a 2006 Topps '52 #170.
Keefe Cato was drafted by the Reds in 1979 and debuted for them in 1983. His entire big league career consisted of 12 relief appearances over the '83 and '84 seasons, all for Cincinnati. Cato holds the distinction as the first major leaguer to come out of Fairfield University. Signed is a 1985 Topps #367.
