In this article, we will formulate a Diamondbacks vs Athletics prediction for this MLB game on Saturday, August 2, at Sutter Health Park in Sacramento, California. Let’s take a look at the prediction for this MLB matchup.

Arizona Diamondbacks Betting Preview

The Arizona Diamondbacks (51-59, 25-31 Away) lost nine of their last ten and are on a six-game losing streak right now. The Diamondbacks were swept by the Astros, lost to the Pirates, and then were swept by the Tigers. Arizona continued in losing fashion with a 5-1 defeat against the Athletics on Friday. Corbin Carroll drove in the lone run for the offense, while Anthony DeSclafani took the loss after allowing four runs on five hits with no strikeouts and two walks in 2.1 innings.

This season, the Diamondbacks average 4.81 runs per game (7th in the MLB) on a .248/.323/.435 triple-slash. When it comes to pitching, the Diamondbacks’ staff has a 4.60 ERA (25th) and 1.34 WHIP (24th). Geraldo Perdomo leads the Diamondbacks with a .276 batting average, 11 home runs, and 75 RBI this season.

Zac Gallen will take the mound for the Diamondbacks on Saturday. The 29-year-old right-hander has a 7-12 record in 22 starts this year with a 5.60 ERA and 1.35 WHIP in 127.0 innings.

Athletics Betting Preview

The Athletics (49-63, 23-32 Home) won seven out of the previous eight games. The A’s shocked the Houston Astros in a four-game sweep on the road and then defeated the Seattle Mariners. The Athletics opened this series against the D-backs with a 5-1 victory last night. Shea Langeliers led the offense with two RBI, while Jacob Lopez got the win after allowing no runs on five hits with five strikeouts and two walks across 5.0 innings of work.

This year, the Athletics average 4.35 runs per game (15th in the MLB) on a .251/.317/.428 triple-slash. When it comes to pitching, the Athletics’ staff has a 4.99 ERA (28th) and 1.40 WHIP (26th). Brent Rooker leads the Athletics with a .274 batting average, 23 home runs, and 63 RBI this season.

The projected starting pitcher for the Athletics is J.T. Ginn, who is 2-2 in six starts this season, with a 3.89 ERA and 1.18 WHIP in 44.0 innings.

Diamondbacks vs Athletics Prediction

The Athletics won six of the previous ten H2H encounters, and I am backing them to win again because the Diamondbacks are just a wreck of a team right now. They traded their assets away and are in a losing mode, so I am not sure how they’ll act in this game. Zac Gallen has struggled recently; he allowed 4+ runs in seven of his previous nine games and allowed 14 runs in his last three starts. J.T. Ginn, on the other hand, is in a way better form and is coming from a 2.25 ERA in July. Ginn shut the Astros out in his most recent start, and I am backing him to have another strong outing on Saturday. Go with the A’s.
