Detroit Tigers give up 19 hits in 15-7 blowout loss to Seattle Mariners

Before the Detroit Tigers’ game against the Seattle Mariners on Saturday, July 12, starting pitcher Casey Mize had not given up more than four earned runs in a game throughout his 2025 All-Star season.

He gave up five earned runs in the third inning alone on Saturday. And then the Mariners added a whole lot more later on.

Much like his All-Star teammate Tarik Skubal did on Friday, July 11, Mize put in his worst start of the year right before the All-Star break as the Tigers lost 15-7 to the Mariners at Comerica Park. It was the most runs the Tigers have allowed in a game this season.

Mize finished the game allowing six earned runs on six hits over three innings pitched. It was Mize’s shortest outing of the season by both innings and pitch count (68), as he raised his season ERA from 2.63 to 3.15 on Saturday.

The crushing blow of the afternoon was a three-run home run from Seattle first baseman Luke Raley in the fifth inning, which gave the Mariners a 6-1 lead. But the team had already established their offensive rhythm well before.

Down 1-0 in the top of the second inning, the Mariners tied the game after left fielder Randy Arozarena led off the inning with a single and a stolen base. Mize got the next two batters out, but Mariners right fielder Dominic Canzone drove Arozarena in with a well-struck single up the middle on the first pitch he faced.

After a double from Mariners second baseman Cole Young led off the third inning, shortstop J.P. Crawford broke the tie with an RBI single, giving Seattle a 2-1 lead. Later in the inning, catcher Cal Raleigh drove center fielder Julio Rodríguez in with a sacrifice fly to right field, Rodríguez initially finding himself on third base after a bad throw from catcher Jake Rogers gave Rodríguez a steal of second base and an advancement to third base.

The running game played a critical role early on for the Mariners, with both of Seattle’s runs initially getting into scoring position via a stolen base. Both Rodríguez and Arozarena each attempted two steals in the first three innings, with the Tigers only turning one of those attempts into an out after Mize picked off Rodríguez at second base in the first inning

Righty Keider Montero entered the game for Mize in the fourth inning with the Tigers down 6-1. A one-out, RBI single from Rodríguez off Montero in the fourth scored third baseman Ben Williamson from first, giving the Mariners a 7-1 lead.

Rodríguez added his second home run of the series in the sixth inning, a solo shot off Montero that gave the Mariners an 8-4 lead, while a two-out RBI from Williamson in the seventh gave the Mariners their ninth run of the game. Arozarena's two-run shot in the eighth gave the Mariners their 11th run, their second straight game with double-digit runs against the Tigers after scoring 12 on Friday.

A bases-clearing double from Crawford highlighted a four-run ninth as the Mariners set their season-high in runs. The Mariners offense also registered 19 hits on Saturday, their highest total in a game in 2025.

Tigers bats can't keep up despite Greene's 4 RBIs

Tigers left fielder Riley Greene had his seventh game with at least 4 RBIs on Saturday, but they marked a big part of a Tigers offensive output that fell short against Seattle.

With the Tigers down 7-1 in the fifth inning, Greene poked a George Kirby splitter to left field, just far enough to clear the wall for a three-run home run, his 23rd of the season. The home run gave Greene his 77th RBI of the year, eclipsing his previous career high (74 in 2024) in 43 fewer games played.

It brought the Tigers back into the game with the lineup struggling through the first four innings. But it wasn't nearly enough to keep up with Seattle.

After Colt Keith walked to lead off the first inning, Gleyber Torres smacked a double to the gap in left-center field, extending his career-high on-base streak to 24 games. It’s the longest active on-base streak in the American League and is the first time a Tiger has had a 24-game on-base streak since Kerry Carpenter from Aug. 2-28 of the 2023 season. 

Greene drove Keith in two batters later on a shallow fly ball to left field to make it a 1-0 game. Arozarena caught the ball on the run but sailed a throw to home plate that catcher Cal Raleigh couldn’t reach, allowing Torres to reach third.

Spencer Torkelson then reached after getting hit in the arm and Zach McKinstry loaded the bases after a walk, but Matt Vierling couldn’t turn in a two-out RBI, grounding into a fielder’s choice to end the inning with the Tigers ahead.

It was the only lead the Tigers had all game.

A seventh-inning RBI single from Wenceel Pérez and a two-run home run from McKinstry in the eighth brought the Tigers back within four runs, as they cut Seattle's lead to 11-7. A walk to Colt Keith brought the tying run in Gleyber Torres to the plate with one out, but a soft lineout against Mariners' reliever Matt Brash and a groundout from Pérez ended the threat.

With the loss, the Tigers tied their season-worst losing streak at three games. They look to avoid the sweep against the Mariners on Sunday, July 13, with first pitch at Comerica Park scheduled for 1:10 p.m. ET.
