White Sox acquire prospect Gillaspie from Rays

The White Sox have added another talented prospect to their farm system as part of their grand rebuild.
Chicago acquired first-base prospect Casey Gillaspie from the Rays on Thursday in exchange for Major League left-handed reliever Dan Jennings, both clubs confirmed. 

Gillaspie, who was the Rays' No. 10 prospect, slots in at No. 14 in a White Sox system seemingly getting deeper by the day. The 24-year-old switch-hitter was batting .227/.296/.357 with nine homers, two triples and 15 doubles in 95 games at Triple-A Durham. He was put on the disabled list after fracturing his big toe on a foul ball Tuesday but is expected to be back in one to two weeks. 
The younger brother of Giants infielder Conor Gillaspie was taken 20th overall in 2014 out of Wichita State. He's shown some pop during his pro career, hitting 17 homers in 79 games in his first full season and 18 over 132 contests between Double-A and Triple-A last year. That power is his loudest tool, but it hasn't been as prevalent in 2017 during his return to Durham. 
Gillaspie has only played first base during his career -- a position held down on Chicago's South Side by All-Star Jose Abreu, who won't become a free agent until after the 2019 season. Should Gillaspie turn the power back on, it's possible one of the two could take over full-time designated hitter duties to get his or Abreu's bat in the Major League lineup. 

The Nebraska native joins Eloy Jiménez, Blake Rutherford, Dylan Cease, Ryan Cordell and Ian Clarkin as solid prospects who've been added to the White Sox system in trades this month.
Jennings gives the Rays a much-needed lefty option out of the bullpen. The 30-year-old put up a 3.45 ERA with 38 strikeouts and 19 walks in 44 1/3 innings for the White Sox this season. He's been particularly tough against lefties, holding them to a .169 average in 85 plate appearances.
