The Tampa Bay Rays make a move to bolster the bullpen by adding southpaw Dan Jennings from the Chicago White Sox for first base prospect Casey Gillaspie, according to ESPN’s Jerry Crasnick. To make room for the 30-year old southpaw, the Rays designated Diego Moreno for assignment.
The Rays needed bullpen help and they get that in Jennings. The Rays have been lacking a reliable southpaw in the bullpen since trading away Jake McGee for Corey Dickerson, which that move has paid of greatly from an offensive standpoint.
Furthermore, the former White Sox and Marlins pitcher has had a pretty darn good track record in the pros. He owns a career ERA of 2.86 in 281 games (261.1 innings of work) and punching out 214 hitters in those 281 games.
In addition, Jennings has pitched well this year, but his ERA has been in the mid three’s (3.45), which is still good. The southpaw has appeared in 48 games (44.1 innings) while striking out 38 batters and holding left-handed hitters to a .164 batting average.
Now, it was worth trading away Casey Gillaspie, as the Rays have highly ranked first baseman prospects in Jake Bauers and Brendan McKay. Bauers is in Triple-A and McKay is in short season Single-A (Hudson Valley). Also, it makes more sense with Jennings being controllable for another two years via arbitration.
Finally, Jennings will be the main southpaw for the Rays from here on out, plus he will join Alex Colome, Brad Boxberger, and Tommy Hunter near the end of games in key situations.
Note: Since the first day of August back in 2015, Jennings has had the third best American League reliever ERA (2.33). He is trailing Zach Britton (1.41) and Andrew Miller (1.65).
