Diamondbacks vs Orioles MLB Betting Preview

The Diamondbacks bounced back with a win against the Orioles on Tuesday after blowing a huge lead on Monday. That win put them two games over .500 this year and can win the series in Baltimore today.

Taking the ball is one of the more pleasant surprises of the 2026 season for the Diamondbacks — southpaw Eduardo Rodriguez. He looked pretty washed up, posting an ERA over 5.00 the past two years. This year, E-Rod is running a 0.50 ERA through three outings.

Some regression is sure to come. E-Rod has a 0.50 ERA with a 3.44 xERA and a 3.52 FIP. The underlying numbers point to his unsustainable 96% strand rate and 0.50 HR/9 as why he'll regress.

I think Rodriguez might be legit again, though. He's throwing his fastball less and his change-up more, and it's worked. Rodriguez boasts a terrific 81% barrel rate, 78% hard hit rate, and a career-best 50% ground ball rate. As a result, his strikeout per nine is just 5.5, and it has never been lower than 7.12 in his decade-long big league career.

To me, it's a small sample type thing. The ground-ball thing is legit, but the swings and misses will return. Matchup-wise, Rodriguez faced the Braves, Mets, and Dodgers, who all rank 15th or better in strikeout rate. The Braves strike out 19% of the time, 20% for the Mets, and 22% for the Dodgers.

The Orioles swing and miss plenty, ranking 22nd with a 24% strikeout rate. Every player in the Orioles regular lineup is around league average or worse in strikeout rate. Dylan Beavers punches out 20% of the time, which is about the best you'll find for the Adley Rutschman-less Orioles.

Assuming Baltimore inserts Coby Mayo back into the lineup, eight of the nine starters run a strikeout rate of 22% or worse. Five of the Orioles starters punch out 27% of the time or more, which is around the 25th percentile.

How To Bet My Diamondbacks vs Orioles Pick, Betting Analysis

With that said, we can get a discount on Rodriguez's strikeout prop after a three-start stretch where he didn't get many punchouts against a team marred with swing-and-miss issues,

In case you're looking for other bets, I'll touch on the Orioles starter, Kyle Bradish. In three outings, Bradish has a 5.27 ERA with a 3.21 xERA and a 3.63 FIP. The luck will eventually shift for the promising right-hander for the Orioles, as long as he stops walking 5.93 batters per nine. The swing and miss stuff is there, punching out 11.20 per nine, but he's walking the yard.

As for the Diamondbacks offense, I have some real long-term worries. The trio of Corbin Caroll, Ketel Marte, and Geraldo Perdomo is awesome, but the bottom of the order is brutal. That's why they sit 24th in wRC+. While they should improve from 24th, it'll be tough to be a top-15 offense with dead weight bringing down the top of the lineup.

Pick: Eduardo Rodriguez Over 5.5 Strikeouts (-151)
