Here are five things to watch and predictions as the Mets and Mariners play a three-game series in Seattle starting on Monday at 9:40 p.m. on SNY.
5 things to watch
The reverse engineered rotation
The first two games of this series will feature Sean Manaea and Jonah Tong, but it's possible neither of them starts.
Manaea, who is basically replacing David Peterson in the rotation, will enter after opener Austin Warren on Monday.
On Tuesday, Tong will be on the mound in a bulk role, but it hasn't yet been revealed whether he'll start or enter after an opener -- Tong has been utilized after an opener in his first two big league appearances this season, tossing 6.2 scoreless innings.
What the Mets are doing might be viewed as relatively unorthodox by some, but it is becoming a more prevalent strategy throughout the game.
It's also a different (and better) strategy than the one the Mets used at times last season, when they often had straight bullpen games where they didn't use a traditional starting pitcher to eat innings.
Juan Soto is still scorching hot
Soto had a monster weekend as the Mets swept a three-game series from the Marlins, with four hits (including a grand slam), two walks, and five RBI.
In 65 plate appearances over 15 games since May 14, Soto is hitting .382/.469/.873 (1.341 OPS) with nine homers and 18 RBI.
For the season, he is slashing .305/.397/.597 (.994 OPS) with 13 homers. Even after missing roughly three weeks due to a calf injury, Soto is on pace to finish the year with 36 home runs, which would be the third-highest total of his career.
Among players who have played 42 games or more this season, Soto's .994 OPS is tops in the National League and third-best in baseball, behind only Ben Rice of the Yankees (1.056) and Yordan Alvarez (1.050) of the Astros.
Is Marcus Semien turning a corner?
Ahead of the series against Miami, Semien had notched just three hits in his prior 28 at-bats dating back to May 20.
In 221 plate appearances over 56 games to that point, Semien was slashing .213/.264/.307 (.571 OPS, 64 OPS+).
The struggles were deep enough to wonder whether the Mets could shift Semien to a bench role once Francisco Lindor returns from the IL, with Bo Bichette shiftingback to third base and Brett Baty taking over for Semien at second base.
Semien rose to the occasion against the Marlins, though, reaching base seven times in 12 plate appearances (five hits, two walks) while raising his OPS for the year to .615.
The Mariners are flying high
After falling to 23-27 on May 19, the M's have gone 8-2 over their last 10 games, including winning their last six in a row with three-game sweeps over the Athletics and Diamondbacks.
The surge has been enough to catapult Seattle into first place in the mediocre AL West -- the 31-29 Mariners are the only team at .500 or better in the division.
Julio Rodriguez has been hot amid Seattle's hot streak, with homers in three of his last four games.
J.P. Crawford, who is on a seven-game hitting streak, has also picked things up.
One player the Mets won't see against Seattle is 2025 AL MVP runner-up Cal Raleigh, who is on the IL with an oblique injury. Raleigh was struggling badly before his injury, hitting a paltry .161/.243/.317 with seven homers in 41 games.
Hancock, Gilbert, and Kirby
The Mariners' calling card remains their elite starting pitching.
Seattle has given up just 225 runs this season, which is second-best in the AL and sixth-best in MLB.
A lot of that has to do with Emerson Hancock, Logan Gilbert, and George Kirby -- the trio of starters who will toe the rubber against the Mets this week.
Hancock has been especially impressive this season, allowing two runs or fewer in eight of his 11 starts.
Predictions
Who will the MVP of the series be?
Soto is as locked in as he's ever been as a Met.
Which Mets pitcher will have the best start?
Freddy Peralta
The Mets need more from Peralta, who couldn't make it through five innings this past Friday against the Marlins.
Which Mariners player will be a thorn in the Mets' side?
Randy Arozarena
