On July 4,1951 In a wild doubleheader featuring a double ejection of manager Charlie Dressen, the first-place Dodgers sweep the Giants, winning 6 – 5 in 11 innings, and 4 – 2. The Dodgers drive out Sal Maglie in the opener after the Giants build a lead on homers by Don Mueller and Willie Mays. Brooklyn counters in the 8th with a pinch homer by Roy Campanella, a homer by Pee Wee Reese, and a tying single from Gil Hodges. Bobby Thomson’s homer in the 11th puts the Giants ahead by one, but Preacher Roe wins it with a squeeze bunt. Ralph Branca wins the nitecap with homer help from Hodges and Duke Snider. Dressen is tossed in the 2nd inning of the second game for protesting pitch calls; after he takes a seat behind the dugout umpire Scotty Robb tosses him a second time. The victories put Brooklyn 6 1/2 games up.
