Moncada will require surgery on his right knee, Francys Romero of BeisbolFR.com reports.
Moncada was shifted to the 60-day injured list earlier Monday, and those his injury had previously been described as knee inflammation, the limited progress he's made since suffering the injury in late May looks to have prompted him to opt for surgery. While a specific timetable is unclear, the expectation is that Moncada will be able to return at some point after the All-Star break.
