Mike Dunn is drawing trade interest, according to Nick Cafardo of the Boston Globe.

Dunn's ERA ballooned to 4.50 year last year amid control issues but he's been a solid lefty specialist throughout his career. Now would be the ideal time to trade him as Dunn is entering the last year of his contract. It's possible Dunn's heavy workload could scare teams away. He's made 222 relief appearances over the last three seasons.
