The Seattle Mariners open a four-game series at the Texas Rangers on Friday, July 24, with a chance to seize first place in the American League West.

Texas holds a half-game lead over the defending division champions, who sit at 51-52 after a frustrating first half that paired the AL's fourth-best WHIP with its 29th-ranked batting average.

For Bellevue-area fans who watched last year's squad reach the brink of the franchise's first World Series appearance, the 2026 Mariners have been maddening.

The pitching keeps delivering

Seattle's staff ranks fifth in ERA (3.59) and fourth in WHIP (1.18) across all of baseball, per Bleacher Report team data through mid-July.

Even in June, the Mariners' worst pitching month, the team posted a 4.20 ERA that still ranked seventh in the American League, according to the Bellevue Reporter's Benjamin Ray.

Bryce Miller has posted a 2.16 ERA through seven starts since returning from the injured list Wednesday, May 13. Emerson Hancock, the No. 5 starter, lowered his arm slot and found another gear: a 3.17 ERA, 1.01 WHIP, and 94 strikeouts in 10 starts.

His four-seam fastball ranks as the ninth-best pitch in baseball by run value, per Baseball Savant.

Closer Andrés Muñoz has converted 17 saves behind a rotation led by Logan Gilbert (119 strikeouts, 8-6 record).

The bats haven't kept up

The numbers are stark. The Mariners rank 29th in batting average (.227) and 28th in runs scored (396), per Bleacher Report.

Cal Raleigh, the 2025 AL MVP runner-up who hit 60 home runs last season, has played only 65 of 97 first-half games due to injury. In those 65 games he struck out 91 times, most among active Mariners, and posted a .271 on-base percentage, the lowest on the team.

He showed signs of life Tuesday, July 21, launching his sixth career grand slam in an 8-0 win over Cincinnati that pushed Seattle a half-game ahead of Texas.

Josh Naylor's best month was May (.296/.350/.352). In every other month he hit below .270. His 12.6% strikeout rate remains the lowest on the roster, and the Mariners need that contact: four hitters strike out at 21% or higher.

Through Tuesday, July 22, Naylor was hitting .258 with 12 doubles, eight home runs and 37 RBIs.

The bright spots: Young and Arozarena

Cole Young, the Mariners' 2022 first-round pick, has 11 home runs through 77 games compared to just four all of last season. He also has 14 doubles and a .990 fielding percentage at second base, second among AL second basemen. June was his best month: .295/.333/.457 in 27 games.

Randy Arozarena leads the team in WAR and batting average (.281). He hit .298 in April, .290 in May, and reached base at a .364 clip in June, per the Bellevue Reporter. One blemish: a lack of hustle in the outfield on Friday, July 10, in Tampa Bay cost pitcher Luis Castillo a run when the next pitch left the yard.

What's next

Julio Rodriguez, a three-time All-Star, returned to the lineup Saturday, July 18, after missing time with a concussion. Through 87 games he's hitting .259 with 14 home runs and 40 RBIs.

Bleacher Report projects Seattle as a deadline buyer ahead of Monday, August 3, citing one of baseball's deepest farm systems and noting the club went 17-1 last September. First up: the four-game showdown in Arlington with the division lead up for grabs.
