Mariners boost offense, trade for outfielder Teoscar Hernández

The Seattle Mariners made one of the first big moves of the offseason by acquiring outfielder Teoscar Hernández from the Toronto Blue Jays in exchange for two pitchers on Wednesday.

Fresh off the team’s first playoff appearance in more than two decades, the Mariners added a slugging right-handed bat to their lineup with the acquisition of Hernández and addressed one of their offseason needs by finding a corner outfielder.

Hernández hit .267 with 25 home runs and 77 RBIs in 131 games last season for the Blue Jays and joined Mookie Betts as the only outfielders in baseball with at least 35 doubles and 25 homers. Hernández was an All-Star starter in 2021 and finished that season hitting .296 with 32 homers and 116 RBIs for Toronto.

He immediately will slot into the middle of Seattle’s batting order and could end up being a replacement in right field for Mitch Haniger, who is a free agent.

“We began our offseason with the intent to add impact and length to our lineup,” said Jerry Dipoto, the Mariners’ president of baseball operations. “In adding Teoscar to an already solid foundation, we feel we’ve become a far more dangerous offensive club.”

Right-handed reliever Erik Swanson and minor league lefty Adam Macko are going back to Toronto. The Blue Jays were looking to clear salary for 2023 and also needed bullpen help with swing-and-miss stuff, which Swanson is expected to provide.

Swanson was 3-2 with a 1.68 ERA and 70 strikeouts in 53 2/3 innings last season.

For now, Hernández is a one-year acquisition by Seattle. He is entering his final season of being eligible for arbitration before hitting free agency after the 2023 season.

Hernandez made $10.65 million last year with the Blue Jays. He’ll turn 31 next October during what the Mariners hope is another playoff run.

While Hernández likely slots into right field should the Mariners not bring back Haniger, the deal was not made with defense at the forefront. This was a move to bolster an offense that at times last season struggled to score runs and leaned a little too much on its pitching staff to win close, low-scoring games.

Hernández has posted an OPS above .800 in each of the past three seasons. And he has played well in Seattle, hitting .357 with three homers and seven doubles in 16 career games at T-Mobile Park.

Seattle will lose a key piece of its standout bullpen from the past two seasons with Swanson’s move. Swanson was primarily a sixth- or seventh-inning option for Seattle, but he was called upon to close out games at times. He seemed to fall out of favor for the Mariners during the postseason and made just one appearance in five games.

Macko dealt with injuries for most of the 2022 season with Single-A Everett. He was rated one of the top-10 prospects in the Mariners organization by some scouting services but pitched in just eight games last season.
