Wolf, 36, was 3-10 with a 5.69 ERA for the Milwaukee Brewers this season before being released Aug. 22.
He was not claimed on waivers, and therefore was eligible to sign with anyone for the prorated major league minimum.
He has to be in the organization by Aug. 31 to be eligible for the postseason. Given his experience – he has appeared in 371 big-league games and made 366 starts in a 14-season career – he obviously will be signing in Baltimore to be on the 25-man roster.
Wolf is 130-117 in his career with a 4.19 ERA for five different teams. He has never pitched in the American League.
Saunders will make his Orioles debut on Wednesday in a start against the Chicago White Sox.Copyright © 2015, The Baltimore Sun
