I think a healthy M's high-leverage bullpen group is probably the best all around. They have 5 legit high-leverage arms, with Munoz, Brash, and Santos all being legit closer-quality (when healthy...both Brash and Santos have been on the IL). Brash and Munoz combo last year was filthy, and they've only improved the group this year.

All these guys can hold/save:

Munoz
Brash
Santos
Speier
Stanek

Munoz is not pitching his best to start the season, but his stuff is great.
