Shohei Ohtani's performance in Game 4 of the NLCS is already being heralded as the great individual performance in MLB history, postseason or not. But is Ohtani the greatest player the league has ever seen?

Shohei Ohtani celebrated his historic game with a day out in the most normal fall activity with dog Decoy before the Los Angeles Dodgers play in the World Series.

Had anyone chosen an unfortunate moment to blink, the sounds echoing around a nearly empty Dodger Stadium would have told the whole story. An impossibly loud crack of the bat. Immediate exclamations of awe.

In tossing six scoreless innings and hitting about 1,430 feet of home runs, Shohei Ohtani put up probably the most unique performance in postseason history Friday in NLCS Game 5 against the Brewers.

The documentary "Diamond Diplomacy" traces Japanese and American history through the lens of baseball. Shohei Ohtani is among the film's stars.

And if you're curious, one pitcher in history has ever had a three-homer game in the regular season. It was Jim Tobin of the 1942 Braves. He went 3 for 4 with three homers and four RBI. He threw a complete game, too. He also allowed five runs (three earned), though.
