Taylor, 23, is one of the better arms in the M's system. He made his debut last season, going 0-0 with a 3.72 ERA in 21 games. He earned one save and struck out 25 batters in 19.1 innings. He began this season on the injured list with a lat strain and has only made four big-league appearances.

He's pitched to an ERA of 12.00 in those appearances, and he's also struggled at Triple-A Tacoma. With the Rainiers, he's 0-2 in nine games, pitching to a 7.36 ERA. He has one save and should factor into some lower-leverage spots for the M's during his tenure, at least initially.

Thornton, 31, is in his seventh year with the Blue Jays and Mariners. A dependable reliever since arriving in Seattle in 2023, he's struggled this season as well. He's 1-0 with a 5.87 ERA, striking out just 11 in 15.1 innings. He's been victimized by the home run ball, giving up five in 16 games.

The Mariners enter play on Friday at 22-14 and in first place in the American League West. They are trying to win their first division title since 2001.

First pitch between the M's and Jays is 6:38 p.m. PT.
