The White Sox received left-handed pitcher Sean Bierman, a former 10th-round draft pick, as well as shortstop Ben Kline, a former 32nd-round selection.
Bierman went 6-5 this past season with a 2.55 ERA in 18 appearances (14 starts) on two separate Single-A levels. Kline, who led all Rays farmhands with a .333 batting average in 2012, batted .246 this past season in 40 games over three different levels.
Crain was on the disabled list at the time of the trade with a bout of shoulder tendonitis and never pitched with the Rays. He became a free agent at the conclusion of the season.
The right-hander posted a 2.10 ERA in 156 appearances over three seasons with the White Sox. He had a 0.74 ERA in 38 appearances in 2013 before his injury surfaced.
