PHOENIX -- The A's bullpen, though different in makeup, remains a great strength.
The club will begin the regular season without the injured Sean Doolittle and the demoted Ryan Cook, yet top to bottom, the bullpen is loaded with assets, starting with presumed fill-in closer Tyler Clippard. Manager Bob Melvin is expected to make an official announcement on that soon.
And even without Cook, who was sent to Triple-A Nashville on Tuesday to work out mechanical issues, Clippard will have a strong right-handed setup man in Dan Otero, known as the "jack of all trades down there," said Melvin.
Otero has a 2.01 ERA in two seasons with the A's, and last year he appeared in every inning but the first.
"He's just moved himself up into a guy that's one of the best at what he does," Melvin said, "and unique because he can give you one-plus, he can pick up a starter in the fourth and give you two-plus in a game you still feel like you have a chance to win, he can give you the eighth, he's pitched the ninth."
