The Giants and White Sox swapped a pair of Minor Leaguers on Friday, with right-hander Jeff Soptic going to San Francisco in exchange for infielder Conor Gillaspie.
Soptic, 21, was 3-3 with a 5.09 ERA the past two seasons in the White Sox organization, after being selected in the third round of the 2011 Draft. He spent all of 2012 in Class A Advanced, going 3-2 with a 5.40 ERA in 27 appearances.
Gillaspie, the 37th overall pick in the 2008 Draft, is a .287 career hitter with 37 home runs in five Minor League seasons. He made it to the Majors just 96 days after his draft date, the quickest Giants player to ever reach the big leagues. The 25-year-old has appeared in 29 Major League games.
The White Sox also designated infielder Lars Anderson for assignment to make room for Gillaspie on their 40-man roster. Anderson was claimed off waivers earlier this month.
