July 25th 1956
On this day in 1956, Roberto Clemente hits a ninth-inning inside-the-park grand slam off Jim Brosnan, giving the Pirates a dramatic 9-8 walk-off victory over the Reds at Forbes Field. The first career round-tripper for the Pittsburgh right fielder, who will hit ten IPHR during his 18-year years with the Bucs, also did not clear the fence.
