Brock Holt stepped out of his Red Sox uniform while visiting patients at the Dana-Farber Cancer Institute on Tuesday.

Joined by wife Lakyn and son Griffin, the Sox free agent sported a #BrockingOutCancer hoodie as he spent time with Jimmy Fund Clinic patients like Collin, 8, of Cohasset. That recently concluded campaign, through which the Holts sold hoodies and tees online, raised $35,000 to help fund next year’s Jimmy Fund Clinic Summer Festival, which Holt presented to clinic staff in the form of a check.
