Los Angeles Dodgers manager Dave Roberts believes Mookie Betts’ stellar performance in Game 4 of the NLCS may have been fueled by a sense of disrespect from the New York Mets who walked Shohei Ohtani three times.

Roberts told reporters after the Dodgers’ 10-2 win that Betts took it “personally” that the Mets may have been trying to avoid pitching against Ohtani.

“And that’s okay. That’s okay,” Roberts said. “And I think he understands that whether it’s a manager sticking up four fingers or you’re deliberately throwing balls out from half a meter, you’re going to go after the next one. So I think Mookie takes it personally, like all competitors should do that. And I think things like that light a little fire under him.”

None of the walks to Ohtani were intentional, but two of them occurred on four pitches. Betts took advantage of the opportunities with at least one runner on base ahead of him, going 4-for-6 with a double, three-run homer and four RBI.

This postseason is an illustration of what makes the Dodgers so dangerous. Ohtani was talked about a lot because of his struggles with no runners on base, but he crushed the ball when someone stepped up.
