The Mariners Can Win If…

The Seattle Mariners are coming off a strong win against the Detroit Tigers, with a score of 15-7. Their offense was on fire, racking up 19 hits, including three home runs. Key players like Randy Arozarena and Julio Rodríguez each contributed with home runs, showing their ability to drive in runs and score.

In the 2025 regular season, the Mariners have demonstrated their power at the plate. They rank 6th in home runs with 131 and 8th in on-base percentage at .323. This shows they can get on base and have the power to drive runners in, making them a threat in any game.

Logan Gilbert takes the mound for the Mariners, with an ERA of 3.88 and a WHIP of 1.02. His ability to limit baserunners gives the Mariners a solid chance to control the game. With their recent offensive output and Gilbert’s pitching, the Mariners have the tools to secure another win.

The Tigers Can Win If…

The Detroit Tigers are coming off a tough game against the Seattle Mariners, losing 7-15. Despite the loss, Riley Greene and Zach McKinstry showed strong performances with home runs. Gleyber Torres also contributed with three hits, including two doubles, showcasing the potential of the Tigers’ lineup.

The Tigers have a solid team batting average of .252, ranking 7th in the league. Their slugging percentage is .425, placing them 6th, and they have hit 123 home runs this season. These stats highlight their ability to generate offense and put pressure on opposing pitchers.

Jack Flaherty will start for the Tigers, looking to improve his 5-9 record. Flaherty’s previous outing against the Rays was strong, with 8 strikeouts over 6 1/3 innings. With the Tigers’ lineup and Flaherty on the mound, they have a good chance to bounce back in their next game.

Tigers Limp Toward Break, Look to Avoid Sweep vs. Mariners

The Detroit Tigers enter Sunday’s finale against the Seattle Mariners on a sour note despite owning the best record in baseball. Three straight losses — including a pair of blowouts at home — have exposed flaws that manager A.J. Hinch hopes his club can clean up before heading into the All-Star break.

The Tigers, who had won five straight before this skid, have now allowed 27 runs over the past two games. With Jack Flaherty taking the mound Sunday, Detroit will look to end the first half on a high note.

Detroit’s Rotation Takes a Hit, Bullpen Stretched

Back-to-back rough starts from Tarik Skubal and Casey Mize have left Detroit’s pitching staff reeling. On Saturday, Mize was tagged for seven runs in four innings, and the Mariners didn’t let up, eventually tallying 19 hits in a 15-7 win.

“We’re in a little bit of a lull right now,” Tigers catcher Jake Rogers admitted. “It happens in baseball. We’ve got one more game before the break, then I hope we come back energized.”

Seattle Stays Hot Behind Rodriguez, Arozarena

The Mariners are trending in the opposite direction. Winners of four of their last five, Seattle has brought their bats to Detroit. Julio Rodriguez homered for the second consecutive game Saturday, while Randy Arozarena and Luke Raley also went deep.

Even more impressive? Cal Raleigh — who had two homers Friday — was the only Mariner in the starting lineup without a hit Saturday. Raleigh enters Sunday one homer shy of tying Barry Bonds’ record (39) for most before the break.

Pitching Matchup: Gilbert vs. Flaherty

Logan Gilbert (2-3, 3.88 ERA) will toe the rubber for Seattle in the finale. Although effective early in games, he’s struggled with efficiency and has failed to pitch past the sixth inning in his last 10 starts. In his most recent outing against the Yankees, Gilbert gave up five earned runs in 5 1/3 innings, with Giancarlo Stanton dealing the big blow via a three-run homer.

Gilbert owns a 1-2 record and 4.19 ERA in four career starts against Detroit.

Opposing him is veteran right-hander Jack Flaherty (5-9, 4.70 ERA), who is coming off one of his best performances in weeks. He allowed just two runs and struck out eight across 6 1/3 innings in a win over Tampa Bay on Tuesday.

“It was a good day,” Flaherty said. “(Catcher Dillon Dingler) called a really good game and the guys made some big plays.”

Flaherty is 2-0 with a 4.41 ERA in three career starts vs. the Mariners.

First-Half Finish Line in Sight

For Detroit, avoiding a sweep is key — not just for morale but to maintain momentum going into the second half. With MLB standings tightening and playoff contenders emerging, every series counts.

Seattle, meanwhile, is playing some of its most complete baseball of the season. Another win could carry the Mariners into the break with confidence and renewed postseason aspirations.
