With the trade of Dan Jennings to the Rays in exchange for switch-hitting first baseman Casey Gillaspie Thursday morning, Jake Petricka is the lone reliever on the active roster from the Opening Day bullpen.
Gillaspie, 24, was rated by MLBPipeline.com as the No. 10 prospect in the Tampa Bay organization and checks in at No. 14 with the White Sox. He batted .227 with 15 doubles, nine home runs, 44 RBIs and 45 runs scored in 95 games this season with Triple-A Durham. He will be placed on Charlotte’s DL with a fractured right big toe, an injury sustained at Buffalo on Tuesday when he fouled a ball off his foot. He is expected to miss one to two weeks.
Conor Gillaspie, Casey’s older brother, played for the White Sox from 2013 to 2015. Casey was drafted by the Rays in the first round (20th overall) of the 2014 Draft out of Wichita State.
Jennings, 30, is tied for second in the American League in appearances this season, with 48, going 3-1 with a 3.45 ERA, 38 strikeouts and seven holds over 44 1/3 innings. He went 9-7 with a 3.12 ERA and 130 strikeouts in 165 games over three seasons with the White Sox after being acquired from Miami on Dec. 10, 2014, in exchange for pitcher Andre Rienzo.
