rubber arm
n.— «Angels pitcher Scot Shields has what’s known in the business as a “rubber arm.’’ For a middle reliever that’s a euphemism for, “Thanks for all your hard work and effort, kid. Here’s $925,000. Have fun setting up, and hopefully you’ll have a semblance of a rotator cuff left when a closer’s job opens up somewhere else.’’» —“For a day, Shields puts White Sox on ice” by Jerry Crasnick ESPN.com Oct. 11, 2005.
