The White Sox have agreed to terms with right-hander Mitchell Boggs on a Major League contract, reports Ken Rosenthal of FOX Sports (on Twitter). Joel Sherman of the New York Post tweets that Boggs will earn $1.1MM. The former Cardinals setup man is represented by CSE.

Boggs, who turns 30 next week, found himself in the closer's role in St. Louis last season after Jason Motte underwent Tommy John surgery. However, despite a strong track record as a setup man, Boggs struggled in his small sample as the Cardinals' closer. The former fifth-round pick allowed 18 earned runs on 21 hits and 15 walks in just 14 2/3 innings for the Redbirds before being designated for assignment and picked up by the Rockies.

He struggled greatly through the summer months in Colorado's minor league system, posting an 8.27 ERA in 16 1/3 Triple-A innings, but Boggs righted the ship upon a promotion to the Majors in September. In 8 2/3 big league innings to close the season, he allowed three runs on seven hits and five walks.

None of those struggles are characteristic of Boggs, who prior to 2013 had posted a combined 3.08 ERA with 7.1 K/9 and 3.1 BB/9 in 201 innings from 2010-12. Boggs had two large problems last season -- a career-worst 7.7 BB/9 and an unnaturally high 26.3 percent homer-to-flyball ratio. The latter of those two marks seems to be particularly fluky, especially considering the fact that Boggs entered the season with a career mark of just 8.5 percent in that regard.
