Topa (knee) has resumed playing catch, Bobby Nightengale of the Minnesota Star Tribune reports.
Topa missed the first four months of the season due to a tear in the patellar tendon of his left knee. He began a rehab assignment July 23 but was shut down Aug. 10 due to right elbow inflammation. Topa remains optimistic that he can return this season, but he still likely has several weeks of building up his throwing before he could start a rehab assignment.
