Dodgers vs. Diamondbacks Pick

  • Dodgers ML -163 (4 units)

Los Angeles is starting Ohtani, who's pitched well, as he should help the Dodgers get the win in the series opener on Tuesday. Ohtani should be able to limit the Diamondbacks' offense, while Los Angeles' offense has been hot and should be able to give Ohtani a lead by the time he leaves the game. Although the bullpen is an issue, Arizona will struggle to score runs, as Los Angeles will win the series opener.

Over/Under Pick for Dodgers vs. Diamondbacks

  • Under 9 runs -120 (5 units)

The under is a great spot here as Ohtani and Pfaadt have both pitched well as of late and should be able to limit the runs. Both starters should go 5-6 innings, allowing only a run or two to help the under cash. This season, Los Angeles is 76-74-6 in hitting the under, while Arizona is 71-75-10, but this pitching matchup is a great spot for the under.
