I would also say the plan to pitch around Ohtani instead of just giving him the IBB was also a bad call. It's an unnecessary, telegraphed fancy play that immediately backfired. Do they really think that Ohtani is dumb enough to swing at pitches off the plate moments after you've had a mound conference? Unless he's a dumb hitter, which I've seen no evidence of, he is going look for a mistake and park it which is exactly what he did.
That grooved fastball was something else tho LOL.
