The Baltimore Orioles, riding a three-game winning streak, host the Arizona Diamondbacks in a compelling interleague clash on Tuesday night. Fresh off a 9-7 victory in Monday's series opener, the Orioles (9-7) look to continue their momentum against a resilient Diamondbacks squad (9-8) that has righted the ship after a tough opening series against the Dodgers.

This matchup features an intriguing pitching duel. For Arizona, veteran right-hander Merrill Kelly makes his long-awaited 2026 debut after starting the season on the injured list. He'll be opposed by Baltimore's Trevor Rogers, who has been stellar early with a 2-0 record and a 1.89 ERA. First pitch from the hitter-friendly Camden Yards is set for 6:35 p.m. ET.

According to the latest odds, the Orioles are listed as -147 favorites on the money line, with the over/under for total runs set at 8.5. A proven computer model that simulates every MLB game 10,000 times has analyzed this contest and identified a strong trend.

The model is projecting the game to go Over the 8.5-run total. This aligns with recent trends for both clubs; the Over has hit in 10 of Arizona's 16 games this season and in 9 of Baltimore's 16. The trend is even more pronounced lately, with the Over cashing in four of the Orioles' last five games and four of the Diamondbacks' last six.

While both starting pitchers are capable of strong outings, the model suggests the offenses—and perhaps the bullpens—will ultimately dictate the pace in Baltimore.
