Arizona Diamondbacks Analysis

The Arizona Diamondbacks started June strong with a four-game winning streak but were swept at Great American Ball Park in Cincinnati, falling three games below .500. The team continues to struggle on the mound with their bullpen posting concerning statistics over the past two weeks. Brandon Pfaadt is set to pitch on Tuesday with a mediocre record and recent subpar performance. Despite a strong offense, the Diamondbacks rank poorly in defense. In their last three matchups, Seattle emerged victorious twice against Arizona.

Mariners pitching staff set to overpower Diamondbacks in upcoming game

Despite the offensive strength of the Diamondbacks, the Mariners appear to have a clear advantage in the upcoming game. Evaluating the pitching matchup, Bryan Woo of the Mariners has been performing well this season in comparison to Brandon Pfaadt of the Diamondbacks who has struggled. Pfaadt's recent performance against the Braves last Thursday, in which he allowed six runs on five hits and two walks in just three innings, further emphasizes the uncertainty surrounding his reliability. Given Pfaadt's underwhelming showing in his last five starts, the Mariners' pitching staff presents a more favorable outlook for success in this matchup.
