The Philadelphia Phillies have reportedly bolstered their bullpen.

According to multiple reports, the Phillies have reached an agreement with free-agent Mike Adams on a two-year, $12 million contract. The deal, which includes a vesting option for 2015, is pending a physical.

The 34-year-old right-hander will set up for closer Jonathan Papelbon, giving the club a formidable late-inning combination.

Adams underwent surgery in October to correct thoracic outlet syndrome, which is caused by a rib pushing down on a nerve and results in a numbing sensation.

Since the 2008 season, he has posted a 1.98 earned run average while tossing 295 innings for San Diego and Texas.

The Phillies also reportedly signed pitcher John Lannan to a one-year contract.

Lannan, a 28-year-old southpaw, has made 134 career starts with the Washington Nationals since 2007, going 42-52 with a 4.01 ERA.
