14th In a game featuring 6 HRs, 3 by each team, the Reds prevail 6–5 in the 10th inning. The game is marred by a controversial play involving Cincinnati’s Ed Armbrister and Boston’s Carlton Fisk.

22nd At Boston, the Sox take a 3–0 lead in the 3rd off Don Gullett, but the Reds rally to tie it in the 7th.
