The Pittsburgh Pirates moved to bolster their bullpen Monday, agreeing to re-sign right-hander Jason Grilli to a two-year deal, according to a major league source.
The deal, which is pending a physical, could give the Pirates the flexibility to trade closer Joel Hanrahan and use Grilli in a ninth-inning role.
Grilli, 36, emerged as one of the most reliable setup men in the National League last season, averaging nearly 14 strikeouts per nine innings and producing a 2.91 ERA.
Hanrahan could earn approximately $7 million in arbitration, and the Pirates have discussed trading him for a comparably priced starting pitcher, sources say.
The Toronto Blue Jays, Chicago Cubs and San Francisco Giants also made offers to Grilli, according to a source.
Grilli's agent is former major leaguer Gary Sheffield.
