Watt spent most of his career as a valuable member of the Orioles’ bullpen-by-committee after going 2-5 in 13 starts (the only starts of his ML career) in his rookie 1966 season. That year he was 7-2 with four saves in relief as the Orioles won the franchise’s first World Championship. His best effort came in 1969 when he was 5-2 with a career-high 16 saves (tied for fourth in the league). Baltimore won the AL pennant, but Watt lost the fifth and final game of the World Series to the Mets. He also lost Game Four of the 1970 WS. He saved Game One of the 1971 LCS, then lost Game Four of the 1971 WS, the first night game in Series history. Watt never had a bad season in his eight years with the Orioles, and was in double figures in saves for four straight years (1968-71), finishing with 80 for his career.
Watt pitched no-hitters on April 24 and May 6, 1965 for Elmira (Eastern League).
