The Chase Continues for New York
The race for the postseason is on, with New York (61-54) clinging to a half-game lead over rival Atlanta for the final wild card spot in the NL. The Mets are 4-3 on this 10-game trip, which also included stops in Los Angeles, St. Louis and Colorado.
Pete Alonso homered twice in Thursday’s 9-1 win over the Rockies, marking the All-Star first baseman’s second mult-homer game of the season and first since April 13. His .725 OPS in July was the lowest of any month this year.
- Oddsmakers remain a bit skeptical of the Mets, pricing them +105 to make the playoffs, though Alonso can change the conversation with a strong finish. As it is, the Mets rank second in the NL and fifth in the majors in longballs, with 146. Its MLB World Series odds are +5000.
New York curiously has fared slightly better on the road this season, where it is 31-25 and hitting .267 as a team. That’s compared to 30-29 and .233 at Citi Field.
The bullpen has been an issue, but it could get a lift with right-hander Reed Garrett (elbow) expected to rejoin the club this weekend. Garrett — who hasn’t pitched since July 9 — has a 3.64 ERA and 63 strikeouts in 42 innings.

Mariners in Fight for First
The Mariners (60-56) narrowly avoided getting swept by Detroit, as Mitch Haniger’s three-run double keyed a ninth-inning comeback in Thursday’s 4-3 win. Seattle also snapped its three-game losing streak and pulled even again with Houston (59-55) atop the AL West.
Oddsmakers still favor Houston to win the division (-150), though the Mariners continue to make things interesting. Seattle has +110 MLB odds to reach the postseason.
The Mariners have leaned largely on pitching. Their staff, headlined by George Kirby, Logan Gilbert and Luis Castillo, leads the majors with 70 quality starts — 10 more than the next-closest team, Philadelphia. The Mariners also have baseball’s best ERA (3.50) and WHIP (1.09), per MLB results.
- MLB injuries, meanwhile, continue to hold back the lineup. Star outfielder Julio Rodriguez — who hasn’t played since July 21 — resumed swinging a bat this week after landing on the IL with an ankle injury. Rodriguez also started running again, though there’s a strong chance he’ll need a minor-league rehab assignment before returning to the Mariners’ lineup. The Mariners also remain without shortstop J.P. Crawford (finger).
Series Probables
⚾Game 1⚾
Friday, 10:10 p.m. ET
Jose Quintana vs Bryce Miller
Quintana was outstanding in July, going 3-1 with a 2.05 ERA in five starts to lower his ERA from 4.57 to 3.89. The veteran left-hander allowed one run or fewer in four of those outings to go with 25 strikeouts over 30.2 innings.
He faces Miller, who is 8-7 with a 3.62 ERA. Like Quintana, he was dominant last month, recording a 1.80 ERA across four starts. The four runs he allowed in his last start were the most since a June 23 loss to Miami in which he gave up six.
Be sure to keep this in mind when making your Mets vs Mariners best picks.
⚾Game 2⚾
Saturday, 9:40 p.m. ET
Sean Manaea vs Logan Gilbert
Manaea went seven shutout innings and struck out 10 in Monday’s 6-0 win over St. Louis. It was Manaea’s second straight start of seven scoreless innings and the third time this year he’s reached double-digit punchouts. The Mets have won eight of his last 10 starts, during which his ERA has dropped from 4.30 to 3.30. He leads the team with eight wins.
- He opposes Gilbert, who is 6-8 with a 3.05 ERA. Gilbert has lost his last three starts, though the All-Star continues to lead the majors with a 0.89 WHIP. He has the fifth-best AL Cy Young odds, albeit as a +4000 longshot.
⚾Game 3⚾
Sunday, 7 p.m. ET
Luis Severino vs Luis Castillo
Severino’s scuffled of late, allowing 11 runs (10 earned) over his last two starts. He also had a 5.81 ERA in July. He’s already thrown 128.2 innings, his biggest workload since 2018 (191.1) with the Yankees.
Castillo, meanwhile, turned in a 1.99 ERA last month. He’s gone at least six innings in six consecutive outings and is tied for fifth in the majors with 16 quality starts.
