Tripp Keister

2014 Carolina League Field Manager of the Year Tripp Keister, 45, enters his fifth season managing inside the Washington Nationals' Minor League organization and prepares to lead a Potomac Nationals club that logged a (65-74) record during the 2015 season.

Keister's resume includes a 2014 Mills Cup Championship, the fifth Carolina League title captured by the Potomac Baseball franchise.

His appointment comes on the heels of his tenure as Washington Nationals' Field Manager representative in the prospect-laden Arizona Fall League. Keister managed the Salt River Rafters to a (16-13) record.

Keister was promoted before the 2014 ledger to lead the P-Nats from his same post with the Class-A Hagerstown Suns, a club he guided to the 2013 South Atlantic League Championship Series.

Keister became the 26th manager in the history of the Potomac Baseball organization in 2014 after spearheading the Gulf Coast League Nationals in 2012 before his posts with Hagerstown (2013) and Potomac, respectively.

Keister oversaw a duo of 2015 mid-season Carolina League All-Stars in RHP Nick Pivetta (traded to the Philadelphia Phillies at the Major League Baseball Trade Deadline for RHP Jonathan Papelbon) and C Spencer Kieboom.

Prior to his professional coaching experience, Keister served as Head Baseball Coach and Associate Athletic Director at Wesley College in Dover, Delaware (NCAA Div. III) from 2006 through 2011 where he earned a Conference Coach of the Year Award, and a school record 30 wins in 2007. Keister also previously made an assistant coaching stop at the University of South Carolina (NCAA Div. I) from 1996 to 1998, and held the head coaching position at Delaware State University (NCAA Div. I) from 1999 to 2000 before assuming an amateur scouting post for the San Diego Padres.

Keister was selected in the 33rd round of the 1992 Major League Baseball Amateur Draft by the New York Mets out of the University of Delaware (Newark, DE) where he was a standout outfielder.

In four Minor League seasons in the outfield, Keister collected a .403 on-base percentage courtesy of 223 walks and only 158 strikeouts in 341 games. The new P-Nats skipper played for the Short-season A Pittsfield Mets (1992), the Class-A Capital City Bombers (1993), the Class-A Advanced St. Lucie Mets (1993-1995), and the Double-A Binghamton Mets (1995).

Keister enters 2016 with a career MiLB managing record of (250-222) inside the Nationals' chain (.530 winning percentage).
