Head-to-head statistics Diamondbacks - Reds

Arizona Diamondbacks Team Overview
Arizona wrapped up their series in Boston with an offensive outburst, but managed just one and four runs in the two games prior to their 7-6 win. The absence of Marte limits the top of the order, and several other key players remain sidelined. However, back home, the Diamondbacks turn to one of the most dependable arms in their rotation, giving them a chance to control the game without needing to rely on high run production.

Cincinnati Reds Team Overview
The Reds were involved in a wild 9-10 shootout last time out, but their previous four meetings with St. Louis were much more restrained-1-2, 6-5, 0-3, and 5-4. After a doubleheader and five games in just four days, the team now heads straight out West. Their offense can put together explosive innings, but facing Rodriguez, their number of quality scoring chances is likely to drop.

⚾ Starting Pitchers
Eduardo Rodriguez enters with a 12-4 record, a 2.71 ERA, and a 1.21 WHIP. In his most recent outing, he went six innings, allowed five hits, issued no walks, and helped Arizona cruise to a 10-3 victory. Earlier this season, the left-hander already faced Cincinnati, giving up just one earned run over 2.2 innings.
Nick Lodolo comes in at 3-2 with a 4.52 ERA and a 1.42 WHIP. After a lengthy layoff, the southpaw is gradually ramping up his workload and logged five innings in his latest start. While his numbers don’t quite match Rodriguez’s, Arizona’s current struggles at the plate could give Lodolo a chance to keep things competitive.
⭐ Editor's Pick
The main concern here is the condition of Cincinnati’s relievers after a grueling schedule and yesterday’s combined 19 runs. However, the starting pitching matchup looks much more stable. Rodriguez is having a strong season, while Arizona are missing Marte and haven’t shown consistent offensive firepower in their recent series. Seven of the last 10 head-to-head meetings have stayed under nine runs, and all three games between these teams this season have finished with no more than eight. Even a 5-4 scoreline keeps this bet safe. We’re backing the under 9.5 total runs in this one.
