Topa signed a minor-league contract with the Yankees on Tuesday, Gary Phillips of the New York Daily News reports.
The right-hander declined an outright assignment to Triple-A Scranton/Wilkes-Barre on Monday after being designated for assignment by the Yankees, but he's now back with the organization on a new deal. Topa fired three scoreless frames in his two outings with the Yankees but struggled to an 8.05 ERA in his 23 outings for the Twins earlier this year.
