Rotowire: Dec 9 / 4:03a ET
News: Petricka, who finished the 2014 season as the White Sox's primary closer, will likely shift back to a setup role after the team signed David Robertson to a four-year contract Monday.
Impact: The White Sox's closer spot spent much of 2014 in turmoil, but Petricka lent a bit of stability for the final month-plus of the year. He should serve as one of the club's top right-handed setup men to Robertson in 2015.

News: Petricka left Saturday's game against the Royals with arm discomfort, Doug Padilla of ESPN.com reports.
Impact: Petricka had only faced two batters before leaving. He was replaced in the ninth inning by Javy Guerra. Petricka had saved five of the past 10 games for the White Sox but was allowing a .333 average to opposing hitters this month.
