One could argue that Shohei Ohtani had the all-time best performance in a postseason game when he hit three homers and struck out 10 batters across six scoreless innings to complete the four-game series sweep over the Milwaukee Brewers in this year's National League Championship Series at Dodger Stadium in Los Angeles. While Ohtani's production in that game is likely unmatched, Los Angeles had minimal pressure for a playoff game, already leading the series 3-0. When factoring in the clutch factor, Ohtani didn't have the best postseason performance in a single game. Jack Morris did.
