After Brock Davis is intentionally walked to load the bases, third baseman Bob Aspromonte blasts a tenth-inning walk-off grand slam off Lindy McDaniel, lifting the Colt .45s to a 6-2 victory over the Cubs. Chicago had tied the Colt Stadium contest in the top of the ninth on a triple by Dick Bertell, a walk to Bob’s brother Ken, and Don Landrum’s RBI single.

On June 11, 1963 After Brock Davis is intentionally walked to load the bases, third baseman Bob Aspromonte blasts a tenth-inning walk-off grand slam off Lindy McDaniel, lifting the Colt .45s to a 6-2 victory over the Cubs. Chicago had tied the Colt Stadium contest in the top of the ninth on a triple by Dick Bertell, a walk to Bob’s brother Ken, and Don Landrum’s RBI single.

The blast fulfills a promise Aspromonte made to a Little Leaguer blinded by a lightning strike who is recovering in Houston. The next year, Aspromonte hits another grand slam on June 11th to down Cincinnati, 5-3.
