Baltimore Orioles Betting Preview

The Orioles are ranked as the third best team in the league for another week in a row. They have gone 7-3 in their recent 10 game play, which includes a win and loss against the Diamondbacks. Jack Flaherty (8-8) will work on the mound for the finale with an ERA of 4.73.

They have been upholding a .255 batting average, yet their rivals are capitalizing with a .244 average against them. This is a solid ratio and it might be just enough to get the job done.

Their on-base percentage (OBP) sits modestly at .320. With an ERA of 4.04 and a slugging percentage of .425, these stats are also better than the Diamondbacks.

The Orioles continue to hold a narrow 2.5 game lead over the Tampa Bay Rays in the AL East. Winning another crucial game here would help offer some breathing room in the division.

Arizona Diamondbacks Betting Preview

The Diamondbacks have moved from 13th to 12th in the power rankings and have an opportunity to potentially slide into the top 10 with a win here. They have gone 5-5 in their previous 10 matchups, but still have some work to do in the division. Zac Gallen (14-6) takes the mound with an ERA of 3.32.

Despite their solid .253 batting average, their pitching struggles, yielding a .254 average to opponents. Essentially, they mirror their hitting achievements with what they concede on the mound.

Their ability to get on base impresses with a .323 OBP, slightly edging out the Orioles. However, their ERA sits at 4.63, a tad higher. Notably, their slugging percentage stands at .418, in close competition with the Orioles' .425.

The Diamondbacks have held down the runner-up spot in the NL West nearly all season, as they trail the Los Angeles Dodgers by 13.5 games. More wind would help, especially against a top team in the league.
