The Mariners’ pitching can also be a factor. They rank seventh in quality starts with 51, showing they can keep games close. Bryce Miller will start the game, and while his ERA is 5.73, he has the potential to improve and help the team secure a win.

Phillies Fire on All Cylinders in Series Opener
The Philadelphia Phillies came out swinging Monday night, smashing the Seattle Mariners with a 12-7 win in the series opener. Fueled by a monster performance from Trea Turner, who went 4-for-5 with a home run and five RBIs, the Phillies looked every bit like the National League powerhouse they’ve been all season.
Bryce Harper added two long homers, and catcher J.T. Realmuto continued his tear with a three-hit outing, including a homer and a double. It was a 21-hit performance from Philadelphia — a statement from a team that had been shut out just two nights earlier.
Manager Rob Thomson credited the collective approach at the plate, saying, “Right now we’re having really good at-bats. It all depends on the next day’s pitcher.”
That pitcher for Seattle is Bryce Miller, returning to the mound for the first time since early June.
Bryce Miller Returns After Long Injury Layoff
Seattle right-hander Bryce Miller (2-5, 5.73 ERA) makes his long-awaited return to MLB action on Tuesday. Elbow issues sidelined the 25-year-old since June 6, cutting short what had been a productive 2024 campaign — he was 12-8 with a 2.94 ERA before the injury bug hit.
Miller isn’t focused on stats anymore, telling reporters his goal now is just to compete and help Seattle push for the postseason. His lone previous appearance against the Phillies came last August when he allowed four runs in 4 1/3 innings.
Bryce Miller – Last 5 MLB Starts (Pre-Injury)
| Date | Opponent | IP | ER | Hits | Result |
|---|---|---|---|---|---|
| May 12 | vs Astros | 6.0 | 1 | 4 | Win |
| May 18 | @ A’s | 5.2 | 3 | 6 | ND |
| May 24 | vs Angels | 7.0 | 0 | 3 | Win |
| May 30 | vs Yankees | 6.1 | 2 | 5 | Win |
| June 6 | @ Guardians | 4.1 | 4 | 7 | Loss |
Seattle hopes Miller can rediscover that dominant form, but he’ll need to do it against a lineup currently firing on all cylinders.
Cristopher Sanchez Looks to Rebound for Philly
Philadelphia counters with Cristopher Sanchez (11-4, 2.45 ERA), who’s been one of the team’s most consistent starters all year. The left-hander suffered just his second loss since early June in his last outing, allowing four runs (three earned) over six innings against the Cincinnati Reds.
Sanchez has yet to face the Mariners in his career, but he’ll need to stay sharp — especially with Seattle catcher Cal Raleigh looming. Raleigh entered the series leading the American League with 47 home runs and 102 RBIs but went 0-for-5 with three strikeouts on Monday.
Cristopher Sanchez – Recent Performance
| Date | Opponent | IP | ER | K | BB | Result |
|---|---|---|---|---|---|---|
| Aug 7 | vs Braves | 7.0 | 0 | 8 | 1 | Win |
| Aug 13 | @ Mets | 6.2 | 1 | 5 | 0 | Win |
| Aug 20 | vs Reds | 6.0 | 3 | 4 | 2 | Loss |
Despite the loss, Sanchez continues to be a workhorse in the Phillies’ rotation, and he’ll look to keep Seattle’s bats quiet after a late-inning rally in Game 1.
Mariners’ Bats Show Late Life, But Fall Short
Seattle may have been overwhelmed early, but they didn’t go down quietly. Cole Young launched a three-run homer and drove in four runs, leading a push that saw the Mariners score seven runs in the final three innings. Manager Dan Wilson said he was encouraged by the fight shown late, but acknowledged they need a full nine-inning effort to beat a team like Philly.
Despite losing five of their last six games, the Mariners still sit within reach of the AL Wild Card — but time is running out.
