Diamondbacks vs Giants action begins a crucial four-game series in San Francisco on Friday, August 28, with Arizona making an important pitching change before the opener. The Diamondbacks recalled right-hander José Cabrera from Triple-A Reno and optioned right-hander Drey Jameson to the minors after Thursday’s game.
The move gives Arizona another starting option during a demanding stretch of the schedule. The club is also preparing for a sudden doubleheader on Saturday, creating an immediate need for additional pitchers. Cabrera is expected to take the mound against Giants right-hander Landen Roupp at Oracle Park.
Diamondbacks vs Giants: Critical Pitching Change
Cabrera made four starts for Arizona before the All-Star break. His overall results were mixed, as he posted a 5.60 ERA during that stretch. His major-league debut was encouraging, however, with five shutout innings. The performances that followed were more difficult, with Cabrera allowing 11 earned runs over 12.2 innings.
Command will be the central storyline for Cabrera. During those later outings, he recorded only nine strikeouts against seven walks. That strikeout-to-walk ratio allowed opposing hitters to remain patient and wait for pitches they could handle. Against San Francisco, limiting free passes could determine whether he gives the Diamondbacks length or forces the bullpen into an early workload.
Powerful Lineup Matchup at Oracle Park
Arizona’s lineup includes several familiar offensive threats. Lars Nootbaar is set to serve as the designated hitter, while Corbin Carroll bats in the middle of the order. Gabriel Moreno catches, Geraldo Perdomo starts at shortstop, and Ryan Waldschmidt is listed in center field.
The Giants counter with Drew Gilbert in right field, Rafael Devers at first base, Bryce Eldridge as designated hitter and Max Kepler in left field. Turner Hill, Shay Whitcomb, Christian Koss and Nate Furman also appear in San Francisco’s starting group. The matchup could test Cabrera immediately, especially if the Giants force him to work deep counts.

Arizona’s Wild-Card Chase Gains Momentum
The Diamondbacks enter the series after taking a valuable series from the Chicago Cubs. Arizona’s 5-4 comeback victory over Chicago, highlighted by Ryan Waldschmidt’s ninth-inning, two-run home run, helped the club remain firmly involved in the National League wild-card race.
Results elsewhere also favored Arizona. The Phillies and Padres both lost series to teams below them in the standings, allowing the Diamondbacks to close within three games of Philadelphia and one game of San Diego. The improved position gives Arizona a meaningful opportunity to gain ground during the final weeks of the regular season.
The remaining schedule may provide another advantage. Arizona has 28 games left, and only nine are against teams currently above the Diamondbacks in the standings. Those tougher matchups include series against the Yankees, Phillies and Padres. The club also faces Miami, which is above .500, but 16 remaining games are against teams with losing records.
That makes the Giants series particularly important. San Francisco is out of the playoff race, while Arizona needs to maximize every opportunity against an opponent below it in the standings. A three-win series would strengthen the Diamondbacks’ position, while a sweep could dramatically improve their chances of securing the third National League wild-card spot.
Why Friday’s Opener Matters
Arizona will not use Eduardo Rodriguez as its starter in the opener, increasing the pressure on Cabrera to provide a competitive start. The Diamondbacks need their rotation and bullpen to navigate the four-game set while also accounting for Saturday’s doubleheader.
For San Francisco, the series offers a chance to disrupt Arizona’s postseason push and improve its record against a division rival. For the Diamondbacks, the mission is straightforward: continue winning against teams below them and keep pressure on Philadelphia and San Diego.
As reported by SB Nation and reflected in the team’s announced lineup and roster moves, the Diamondbacks vs Giants opener has playoff consequences for Arizona despite San Francisco’s position in the standings. Cabrera’s command, Waldschmidt’s recent heroics and the Diamondbacks’ ability to handle Oracle Park will be closely watched.
