Snodgress, 25, was making the move from Minor League starter to reliever at the Major League level after finishing 6-7 with a 3.89 ERA over 21 starts between Triple-A Charlotte and Double-A Birmingham. Snodgress then made his big league debut with the White Sox as a September addition, allowing seven runs (four earned) over 2 1/3 innings during four relief appearances. He was a fifth-round pick of the White Sox in the 2011 First-Year Player Draft out of Stanford.
This move leaves the White Sox with Zach Duke, Onelki Garcia and Eric Surkamp as current left-handed bullpen options, although Carlos Rodon, the third pick overall in the 2014 First-Year Player Draft, could warrant consideration even with his future set as part of the starting rotation.
Carroll, 30, finished 5-10 with a 4.80 ERA over 26 appearances (19 starts) with the White Sox last season, his first in the Majors. He posted a 3-1 ledger with a 1.57 ERA in four starts with Charlotte before having his contract purchased on April 27. Carroll was designated for assignment on Nov. 25 to make room for first baseman Adam LaRoche on the 40-man roster.
These moves Tuesday leave the White Sox 40-man roster at 39.
Tyler Flowers, Hector Noesi, Javy Guerra, Dayan Viciedo and Nate Jones, who are all arbitration-eligible, will be tendered contracts as expected. Flowers stands as the White Sox starting catcher, Noesi is the team's current fifth starter option and Guerra is in the middle to late-inning bullpen mix. Jones is rehabbing from Tommy John surgery that ended his '14 campaign in late July, after he battled through back issues that limited him to five batters faced all season, while Viciedo still could split time in left field.
