Royals vs Diamondbacks Prediction, Best Bet
Eduardo Rodriguez has been phenomenal for the Diamondbacks since returning from injury, posting a 1.98 ERA across five starts. He’s allowed two earned runs or fewer in every outing.
Rodriguez draws one of the weakest lineups in the league tonight. Kansas City ranks in the bottom five in OPS, SLG, and wOBA vs. left-handed pitchers since the start of May. The Royals are dead last in wRC+.
The Royals‘ Kris Bubic gets a tougher matchup, facing a dangerous Diamondbacks lineup that ranks in the top 10 in OPS and wOBA against LHP since the start of May.
The key is the right-handed bats. Arizona will likely throw at least eight righties at Bubic. That’s good news.
Bubic has limited right-handed hitters to a meager .222/.283/.324 slash line. His strikeout rate jumps up by more than 4% against righties compared to lefties.
Pick: First 5 Innings Under 4.5
