The pen has an overall 2.88 ERA in 75 innings pitched through the season's first 20 games, and both Delcarmen and Ramirez have been perfect through 25 1/3 innings pitched thus far.

"It's going to be pretty exciting to see what we can do when everybody gets mixed on there," said Delcarmen, who is perfect in 4 1/3 scoreless innings this season. "All of us are going to try to pick each other up when we need to, and then whoever is going to get the ball will get the ball."

The biggest strength of the seven-man unit: the depth.

Power-armed bullpen guys like Delcarmen and Ramirez have basically been interchangeable parts in the middle innings, and softened the blow of slow starts by both Okajima and Saito.

"Obviously everybody wants to be the setup guy, and come in and be 'The Guy'," added Delcarmen. "But we've got so many power arms that anybody can go in there and get outs. We've got Masterson, Ramon, and the experience of Saito and Okajima. (Manager Terry Francona) has been doing a great job of the last few years mixing everybody in and giving us an opportunity."

The opportunities will just keep on coming as long as Delcarmen and his bullpen brethren keep getting the job done.

RAYS 6, RED SOX 2: RHP Justin Masterson was cruising along with a 2-0 lead until he surrendered six runs in the bottom of the sixth -- including a grand slam hit by Tampa 3B Evan Longoria -- and suffered his first loss of the 2009 season. 2B Dustin Pedroia and 1B Kevin Youkilis scored Boston's two runs and both produced multi-hit efforts in defeat.
