The Pittsburgh Pirates are pushing to trade closer Joel Hanrahan, according to a report from Danny Knobler of CBS Sports.

Hanrahan has been a solid closer for the Pirates the last two seasons, but Pittsburgh may be looking to cash in while his value is at its highest. Knobler's report mentions the Los Angeles Dodgers as one team who could be interested. With proven closers at a premium, it's possible Pittsburgh could land multiple prospects in return. The Dodgers also have a surplus of starting pitching, something which could interest the Pirates.

Since joining the Pirates during the 2009 season, Hanrahan has saved 82 games while posting a 2.59 ERA. Hanrahan struggled some with his control last season, but raised his strikeouts per nine innings to 10.1. He's been selected to the All-Star team in each of the last two seasons.

The Tigers have been rumored to be looking to acquire a closer, but Knobler said the Tigers are not interested in Hanrahan.
