Twins' Perkins could have nerve irritation in left arm, awaits results of MRI

Minnesota Twins closer Glen Perkins underwent an MRI on Thursday after experiencing soreness in his arm earlier this week, and it's believed the 31-year-old is battling nerve irritation, according to the Star Tribune.

Perkins complained of soreness after allowing three earned runs over one inning of work in Tuesday's 4-3 victory over the Detroit Tigers, prompting the club to send him for an MRI. Results of the exam are expected Friday, though surgery is not anticipated for the two-time All-Star.

Perkins owns a 3.65 ERA while collecting 34 saves in 41 chances this season, but has struggled mightily in recent weeks, stumbling to a 14.21 ERA while blowing three saves in his last eight appearances.
