Seattle Mariners Betting Preview

The Seattle Mariners (33-33, 17-16 Away) are going through their worst stretch of the season, during which they suffered seven losses in eight games. After being swept at the hands of the Orioles, the Mariners lost the series to the Angels, and will also lose this one against the Diamondbacks. Seattle was defeated in the first two games; Arizona secured a 10-3 win on Tuesday. Logan Evans took the loss after allowing four runs on seven hits with five strikeouts and two walks in 5.0 innings.

Arizona Diamondbacks Betting Preview

The Arizona Diamondbacks (33-34, 17-17 Home) swept the Atlanta Braves and then were swept by the Cincinnati Reds. Thanks to a couple of wins over the Mariners in the last two games, the Diamondbacks will win the series. In last night’s 10-3 victory, Gabriel Moreno led the offense with three RBI, while Brandon Pfaadt got the win after allowing two runs on nine hits with four strikeouts and one walk across 5.0 innings of work.

This season, the Diamondbacks average 5.09 runs per game (4th in the MLB) on a .254/.333/.449 triple-slash. When it comes to pitching, the Diamondbacks’ staff has a 4.82 ERA (25th) and 1.35 WHIP (22nd). Eugenio Suarez leads the Diamondbacks with a .224 batting average, 18 home runs, and 48 RBI this season.

Eduardo Rodriguez will take the mound for the Diamondbacks on Wednesday. The 32-year-old left-hander has a 1-3 record in ten starts this year with a 6.70 ERA and 1.65 WHIP in 49.2 innings.

Diamondbacks vs Mariners Prediction

The Diamondbacks won six of the previous ten H2H encounters, including the last three. Still, I am going with the Mariners here because I don’t think they will be swept in this series. Also, Bryan Woo is in a much better form than Eduardo Rodriguez this season. Woo did allow four runs in a loss in his most recent start, but he posted a 2.58 ERA in May. Rodriguez, on the other hand, surrendered multiple runs in each of his previous six starts, and allowed a .353 BA in 68 at-bats against the Mariners in his career. Back the Mariners.
