Sean Bradke enters his third season as an assistant softball coach with Siena softball in 2014. He primarily works with Siena's outfielders.
In 2013, Bradke was part of a Siena Softball program which captured its first MAAC Regular Season Co-Championship. Siena posted its second most wins (21) and set a program record with 12 MAAC victories.
In his first season with the program, the Saints tied for their most overall wins since 2005 and most MAAC victories since 2003.
Bradke previously served as the head coach of Niskayuna's modified baseball team. Under his guidance, the team set a school record with 104 stolen bases, and had a cumulative on-base percentage of .485. Niskayuna's outfielders did not record a single error all season long, and tallied five assists as well.
Bradke also serves as the assistant swimming and diving coach at Siena, and has helped guide that program to its fourth and fifth consecutive winning seasons. A native of nearby Latham, Bradke spent five seasons as the head diving coach and swimming and diving recruiting coordinator at SUNY-Potsdam. Hired as the youngest NCAA coach ever at age 19, Bradke led Potsdam to the #1 National seed by the time he was 21.
In 2010, Bradke led Potsdam to a National Championship in one-meter diving and third place finish in three-meter diving at the Division III level. Under Bradke's tutelage, he mentored 2009 NCAA Diver of the Year Nathan LaRowe, while also producing four NCAA All-Americans and three All-American Honorable mentions.
