The Chicago White Sox agreed to a one-year, $4.75 million contract with right-hander Miguel Gonzalez on Thursday.
Outfielder Jacob May was designated for assignment in a corresponding move.
Gonzalez, 33, began last season with the White Sox, who traded him to the Texas Rangers on Aug. 31. He finished 8-13 with a 4.62 ERA in 27 starts last season but struggled after being traded to Texas, going 1-3 with a 6.45 ERA in five starts.
"Bringing Miggy back not only strengthens the options for our pitching staff but also returns another quality individual to our clubhouse," Rick Hahn, the White Sox's senior vice president/general manager, said in a statement.
