The move came hours after the Rays completed a three-game sweep of the Boston Red Sox to get within 3 1/2 games of the American League Wild Card.
Moore wrapped up his Minor League season on Wednesday, taking the loss for the Triple-A Durham Bulls in Game 1 of the International League semifinals. It was a rare blemish on a superlative year that included a nine-inning no-hitter for Double-A Montgomery and a buzz-generating appearance in the All-Star Futures Game.
The 22-year-old left-hander went 12-3 with a 1.92 ERA and 210 strikeouts in 27 starts across two levels. He began the year in the Southern League -- as MLB.com's No. 27 prospect -- and was 8-0 with a 2.20 ERA in 18 starts. Near the end of his stint with Montgomery, he pitched a no-hitter, striking out 11 in an 8-0 victory over Mobile on June 16.
Five weeks later, Moore began a dominant stay in Durham. In his second Triple-A start on July 27, the Florida native recorded a career-high 13 strikeouts and allowed three hits over eight shutout innings against Gwinnett.
The 2007 eighth-round Draft pick ended up going 4-0 with a 1.37 ERA in nine starts while limiting International League foes to a .179 batting average. Over 52 2/3 innings at the Minors' highest level, he struck out 79 while allowing 52 baserunners.
Moore became the first Minor Leaguer in at least two decades to record back-to-back 200-strikeout seasons, although he failed to lead the Minors in that category for the first time since 2008.
Moore had a breakout year in 2010, becoming the first Minor Leaguer since Francisco Liriano in 2005 -- and the first Florida State Leaguer since 1971 -- to record at least 200 strikeouts. In 26 starts for Class A Advanced Charlotte, he went 6-11 with a 3.36 ERA.
