Tom Matchick’s two-run home run gives Detroit a dramatic 5-4 walk-off victory over Baltimore at Tiger Stadium. The rookie shortstop’s round-tripper, the first of only four he will hit in his six-year major league career, comes with two outs off Moe Drabowsky.

During a 6 – 2 defeat, concluding a dismal 2-and-4 road trip for the Pirates, the rarely disappointing Roberto Clemente does what he does so well – break the other team’s heart in their own house and have their fans thank him for it. As Les Biederman of the Pittsburgh Press reports: “Clemente robbed Joe Torre with a lunging catch of his pop fly in the 3rd inning with two on and the hometown Atlanta fans applauded him en route to the bench. They even applauded him when he went to bat in the 4th inning.”

At Yankee Stadium, Baltimore outlasts the Yankees to win, 2 – 1, in 14 innings. New York manages just four hits, including a solo homer by Mickey Mantle, off Bill Dillman.

Cardinals’ pitcher Bob Gibson’s right fibula is fractured by a Roberto Clemente line drive during a 6-3 loss to the Pirates. The injury will sideline the Redbird right-hander until Labor Day, but he will recover well enough to allow only three earned runs in three complete World Series game victories over the Red Sox.

Kansas City A’s pinch-running specialist Allan Lewis ties the major-league record with two steals as a pinch runner in one inning. Lewis does his double in the 7th inning of a 3 – 2 loss at the Minnesota Twins.
