The White Sox have traded lefty reliever Dan Jennings to the Rays for first base prospect Casey Gillaspie, according to Marc Topkin of the Tampa Bay Times.
Jennings is the fourth reliever dealt by the White Sox in 10 days, joining new Yankees David Robertson and Tommy Kahnle and new Brewer Anthony Swarzak. The club has acquired Tyler Clippard, Danny Farquhar, Mark Lowe and Jean Machi as veteran fill-in options, though Clippard is viewed as a candidate to be flipped.
Jennings, 30, owns a 3.45 ERA and 4.56 FIP in 44.1 appearances for Chicago this year. He is under club control through the end of the 2019 season, giving Tampa Bay more than two years of control moving forward.
Jennings is the second reliever to join the Rays in the last week, as the club acquired Sergio Romo in a deal with the Dodgers on Saturday. Tampa Bay is still looking for high-end relief help, being linked to Justin Wilson, Brad Hand, A.J. Ramos and others on the market, but adding a lefty in Jennings is a strong first move.
Gillaspie, 24, was Tampa Bay’s first-round pick in 2014. He has struggled to a .227/.296/.357 line with nine homers for Triple-A Durham this season, plummeting to the no. 8 ranked prospect in a strong Rays’ system (per Baseball America) after starting the year as BA’s 76th-best prospect in all of baseball.
Chicago will hope that their decision to buy low on Gillaspie, who attended Wichita State, will pay off with a change of scenery.
