Relief pitcher John Axford has been traded to St. Louis in exchange for a player to be named later.

Axford, 30, is 6-7 with a 4.45 ERA in 62 relief appearances this season. Though he did not produce a save for the Brewers in 2013, he ranks second on the all-time franchise list in that category (106), trailing only Dan Plesac (133). Axford went 21-19 with a 3.35 ERA and 106 saves in 268 relief appearances with the Brewers from 2009-13. His 46 saves in 2011 set a franchise record. He is eligible for arbitration.

“John has been a big contributor to the Brewers, and we do not go to the playoffs in 2011 without his outstanding performance,” said G.M. Doug Melvin.

“He and his wife, Nicole, will also be missed as contributors to the Milwaukee community."
