Bob Allison hit the first grand slam in @Twins history on this date in 1961. It was the top of the first inning in the first game of a Sunday doubleheader in Baltimore. The Orioles’ Chuck Estrada—who had tied for the league lead with 18 wins the previous season and would win 15 in 1961—walked three straight to start the game, filling the bases for the cleanup hitter Allison, who hit a four-run homer. After giving up a double to Jim Lemon, Estrada was pulled, ultimately being responsible for five runs. Relief pitcher John Papa didn’t fare much better, issuing consecutive two-out bases-loaded walks before Dick Hall—the third pitcher used by Baltimore in the six-run first—got the final out. Allison added a three-run homer in the sixth, establishing a Twins single-game record with seven RBI in the 10-5 win. That record was matched four times before being broken by Glenn Adams with eight RBI on June 26, 1977. Randy Bush also had eight RBI on May 20, 1989. In addition to being the first grand slam in Twins history, Allison's slam was significant in two more ways. It was the first of three grand slams he hit in 1961, which remained tied for the team single-season record with @RodCarew_29 (1976), Kent Hrbek (1985), Kirby Puckett (1992), and @ToriiHunter48 (2007) until rookie Royce Lewis hit FOUR last year. Additionally, it was the first of eight grand slams the Twins hit during their inaugural 1961 season. That is still the team record. The other Twins to hit grand slams in 1961 were Dan Dobbek, Harmon Killebrew, Julio Becquer (a pinch-hit walk-off grand slam on the Fourth of July), Ted Lepcio, and Bill Tuttle.
