Teasley comes to Cleburne with a stellar track record in both international and independent baseball. After pitching in 17 games with as a member of the Tampa Bay Rays organization during his rookie year in 2013, the native of Fort Pierce, Florida has split the next six seasons between Southern Illinois of the Frontier League and Somerset of the Atlantic League.

Teasley was selected by the Rays in the 23rd round of the 2013 MLB Draft after wrapping up his collegiate career at Division-II Saint Leo College. Despite finishing the year with a 2.61 ERA over 41.1 innings of work, Teasley was granted his release in the spring of 2014.

Southern Illinois was quick to pounce, signing Teasley less than a month after his release from the Rays organization. Over the next three seasons, Teasley etched his name into the Miners record book as the all-time franchise leader in wins (28), starts (57), and innings pitched (351.0), while placing second in strikeouts (266). He tossed the franchise’s first no-hitter on June 5, 2014 against the Joliet Slammers as part of a doubleheader.

After aging out of the Frontier League, Teasley signed with Somerset for the 2017 season, which proved to be a breakout campaign for the left-hander. Teasley’s success caught the attention of international scouts, and his contract was purchased by the ChinaTrust Brothers of the Chinese Professional Baseball League for the remainder of the 2017 season.

Teasley rejoined Somerset for the 2018 campaign, and delivered another strong season. Over the course of 16 appearances (15 starts) covering 80.0 innings, Teasley authored a 3.60 ERA with 71 strikeouts to 24 walks. In 2019, Teasley made 17 starts for the Patriots, finishing 6-3 with a 4.20 ERA. He made history on July 26 by tossing nine perfect innings against Long Island, but Somerset failed to score a run and ultimately lost the game 1-0 in 10 innings.
