Mickey Weston

Mickey has been on staff since 1996 and leads the UPI team as our Executive Director. He is also currently in his sixteenth season serving players as the chaplain for the Chicago White Sox.

Mickey was drafted in 1982 by the New York Mets and pitched for fifteen seasons. He had parts of five years in the MLB with the Orioles, Blue Jays, Phillies, and Mets. He later went on to become a pitching coach in the Mets organization for three seasons. Mickey was inducted into the Rochester Red Wings Hall of Fame (Triple-A affiliate of the Orioles) with the lowest E.R.A. (1.98) in the history of the franchise (which spans over a hundred years).

Mickey went on his first mission trip with UPI in 1986 to South Korea. That trip changed the trajectory of his life. He has since traveled to work in partnership with missionaries and local churches in over forty countries around the world. His wife, Lisa, serves the women in professional baseball as the Women’s Ministry Coordinator for Baseball Chapel and as the Women’s Bible Study leader for the White Sox. Mickey and Lisa have also served together on the board of directors of Pro Athletes Outreach for over thirty years.

Brian is our Southwest Director of Operations and coordinates our Arizona Men’s Retreat and Spring Training Bible Studies. He is also currently in his sixteenth season serving players as the chaplain for the Arizona Diamondbacks.

Brian played three years at the University of Louisville where he was fifth in the nation in strikeouts per nine innings in 1995. He went on to play five years of professional baseball with the Brewers and led the organization in appearances in 1997. His career was later cut short after tearing his ACL three times as well as his rotator cuff and labrum.

Brian was impacted by Campus Crusade and Fellowship of Christian Athletes while at Louisville and then got involved with Baseball Chapel during his professional career. In 1996, he went on a mission trip with UPI that he says changed him in ways that he never imagined. Brian would later come on staff with UPI in the summer of 2001.

Luke is our Southeast Associate and Director of Outdoors Retreats. He is also currently in his second season serving players as the chaplain for the Tennessee Smokies (Double-A affiliate of the Chicago Cubs).

Luke played nine seasons in MLB with the Kansas City Royals. He was drafted as the number one overall pick in the 2006 draft after being named the SEC and NCAA Pitcher of the Year and leading the University of Tennessee to the College World Series. In 2009, Luke pitched an eighty-pitch complete game allowing only three hits and one run — a feat that had only been accomplished by five pitchers in the AL over the previous twenty years. He posted a career-high thirteen strikeouts in seven innings just one month later. Luke had his best year in 2013 coming out of the bullpen with a 1.92 ERA and eighty-two strikeouts in seventy innings. In 2015, Luke helped lead the Royals to their first World Series title in thirty years and was the winning pitcher in the final game.

Luke has years of experience in the game, a passion for the outdoors and a love for Jesus that has led him to join the UPI team. He leads small groups for players in the Knoxville area and also coordinates hunting retreats for current and former players.
