Reliever Heath Bell has switched agents, moving from ACES to Dan Lozano's MVP Sports Group, tweets Jerry Crasnick of ESPN.com. As Crasnick notes (also on Twitter), Bell's former agency seems to have done well in securing the three-year, $27MM contract that Bell signed with the Marlins before the 2012 season.
After signing that deal, of course, Bell (along with much of the rest of the Marlins team) fell well short of expectations. Expected to be Miami's closer, Bell only managed to notch 19 saves. Even worse, in the 63 2/3 innings he threw, he posted a 5.09 ERA. Bell's performance lagged in 2012 as his walk rate skyrocketed to a career-worse 4.1 BB/9, to go with just 8.3 K/9.
Bell's current deal does not expire until after the 2014 season. The Diamondbacks possess an option for the 2015 season, but seem very unlikely to exercise it.
