For five seasons, J.R. DiMercurio toiled for the El Dorado Broncos and did it well. In the 31 year history of the Broncos, DiMercurio is one of only two persons to both play and later coach the team. The other is Dan Davis.
DiMercurio played for the Broncos in 2000, 2002, 2003 and 2004. He amassed an excellent .303 batting average and .489 slugging percentage. His 512 at bats are the most of any Bronco as are his 12 sacrifice flies. He slugged 28 doubles and 19 home runs. His home run total is second all-time to Kevin Frederick and his 155 total hits are third all-time.
In 2004 alone, he hit 8 home runs for the Broncos. Although not a base stealer, he compiled an excellent 9 for 10 mark on stolen bases.
J.R. managed the Broncos in 2006, compiling a 38-24 (.613) record. The Broncos finished third in the Jayhawk League and ninth in the NBC World Series.
DiMercurio attended Highlands Ranch High School in Denver and then went to Dixie Junior College in 2000. From there, he went to Wichita State University in 2001 but was redshirted due to an elbow injury. He went to Cowley County Community College in 2002 and back to Wichita State in 2003 where he batted .274. In 2004, he was sidelined with a hamstring injury.
DiMercurio was an assistant coach at Cowley in 2006 and 2007. In 2008, he became a scout for the Minnesota Twins, a position he still holds. J.R. lives in Wichita with his wife Cari, son Rocco and daughter Mora.
