Longtime Milwaukee radio personality Robb Edwards is undergoing quadruple-bypass surgery at a local hospital this evening after suffering a heart attack earlier Tuesday.

Edwards, 61, was most recently heard on WOKY (920 AM), and has also been on other stations such as WTMJ, WBCS and WZUU.

Edwards serves as public address announcer at Miller Park, a position he's held since the stadium opened in 2001. WTMJ morning host Gene Mueller filled in Tuesday night when the Brewers hosted the Los Angeles Dodgers.
