He made manager Ozzie Guillen sweat first, allowing a hit and a walk before getting Andy LaRoche looking to cinch the two-run win.

Bell pitched the eighth inning Monday.

Marlins manager Edwin Rodriguez said Michael Dunn will be his primary eighth inning man after Clay Hensley landed on the disabled list.

Many thought it might be Ryan Webb or Brian Sanches, but Dunn is a fine choice. He has been terrific this season, posting a 1.35 ERA and 1.05 WHIP while striking out 19 over 13 1/3 innings. Dunn says he ultimately wants to be the closer. "What I want to do eventually is to be a closer," Dunn said. "So you take your chances wherever you can get them in the bullpen and try to work your way to the role you want."

Michael Dunn gave up three runs in one-third of an inning Saturday against the Red Sox.

Dunn was just as big of a part of the Dan Uggla trade as Omar Infante was, the but the hard-throwing left-hander is pitching himself out of the Marlins' plans for April. Not only has he given up five runs in 3 1/3 innings, but he's yet to strike out a batter.

Marlins acquired LHP Mike Dunn and INF Omar Infante from the Braves for 2B Dan Uggla.

Dunn, 25, posted a 1.52 ERA and averaged 12.2 K/9 in 38 appearances with Triple-A Gwinnett this past season, but he also averaged 4.8 BB/9. His control was even less impressive after joining the Braves. Despite a 1.89 ERA and 27 strikeouts in 19 innings, he also walked 17. There's obviously potential here, but he shouldn't be a major piece of a trade for a player like Dan Uggla.

Braves recalled LHP Mike Dunn from Triple-A Gwinnett.
