Strop signed with the Cubs on Friday, Jesse Rogers of ESPN.com reports.
Strop was released by the Reds on Tuesday, but he'll return to a familiar destination with the Cubs. He'll report to alternate camp initially, but he could certainly join the major-league roster at some point, especially given the Cubs' bullpen woes this season. The right-hander made four relief appearances with the Reds this year, posting a 3.86 ERA and 3.00 WHIP over 2.1 innings.
