The 38-year-old righthander was released by the Atlanta Braves
last month. He was 3-3 with a 3.92 ERA in 49 appearances this
season. He had 20 saves in 26 appearances.
Wickman joins a bullpen that has been one of the strengths of
the surprising Diamondbacks, who led the NL West by game entering
"We've got arms down there," manager Bob Melvin said, "but
this is another quality arm that's been through it."
Wickman, a two-time all-star, is 63-60 with a 3.58 ERA in parts
of 15 major league seasons.
He would not be eligible for the postseason "but he's a veteran
arm to help us get there," general manager Josh Byrnes said.
