Jeffcoat enters his first season as manager in 2021. As pitching coach with the Railroaders in 2019, Jeffcoat helped craft one of the American Association's most effective pitching staffs in his first season with the club, as the Railroaders 3.90 team ERA finished second on the circuit. Cleburne's pitchers saw a marked improvement across the board from 2018-2019 under Jeffcoat's direction, cutting down on walks (386 - 327) and hits allowed (961 - 892), while increasing the number of strikeouts (736 - 776). Cleburne pitchers Jesus Sanchez and Tyler Wilson were selected as American Association Mid-Season All-Stars.

Jeffcoat brings a wealth of experience to the Railroaders as both a player and coach. Originally a 13th round draft pick of the Cleveland Indians out of Louisiana Tech, the native of Pine Bluff, Ark., made his MLB debut in 1983, the first of three seasons he would spend with Cleveland. Jeffcoat was traded to the San Francisco Giants early in the 1985 season, and then later signed with the Texas Rangers as a free agent prior to the 1987 campaign. It was with the Rangers that Jeffcoat put together some of his best seasons as a professional, including in 1989, when he went 9-6 with a 3.58 ERA in 22 starts. After six seasons in Texas, Jeffcoat finished out his major league career in 1994 by making four appearances for the Florida Marlins.

Over the course of 15 pro seasons, Jeffcoat produced 110 wins to 85 losses, compiling a 3.98 ERA in more than 1,700 career innings.

Jeffcoat came to Cleburne after 16 seasons as head coach at Texas Wesleyan, where he built the Rams into one of the most consistently successful programs in the NAIA. Jeffcoat inherited a program in 2002 that hadn’t produced a 40-win season in more than 20 years, a mark that the Rams would reach five times under his guidance. With more than 500 career victories, Jeffcoat is the all-time winningest coach in Texas Wesleyan history.
