Shohei Ohtani appalled some fans on Wednesday after he appeared to celebrate a stolen base with a lewd gesture ... but upon further review, it seems he was simply shakin' dirt.
Take a look at how the Dodgers superstar got up following a slide into second during the first inning of L.A.'s game against the Phillies in Philadelphia ... he sure looked like he was imitating some R-rated bedroom activity.
He ripped off his glove, put it in front of his junk ... and shook it repeatedly as he stared into his team's dugout.
