Left-handed reliever Jordan Norberto had a career year in 2012 for the A's, establishing himself with a 2.77 ERA and 46 strikeouts in 52 innings pitched.
He thought he had cemented his place in the organization.
Then he hurt his elbow this spring, and when the A's needed room on the 40-man roster in early May for Daric Barton, they released Norberto.
Needless to say, the 26-year-old reliever wasn't thrilled.
According to The San Francisco Chronicle's Susan Slusser, Norberto has filed a grievance against the A's, claiming he should not have been released because he was injured.
"I expected more from the team after the way I pitched for them last year. But I'll work hard and get a job with someone else," Norberto told The Chronicle.
To make matters worse, the elbow injury was worse than first thought and Norberto underwent successful Tommy John surgery to repair torn ligaments this week.
