Mariners Warm Up as Skenes-Level Arms Cool

JULY 10, 2026

Who climbed and who cooled over the past week.

The week did what weeks do: some players caught fire, others hit a wall. Tyler Tolbert went 13-for-19 in Kansas City, while Logan Webb quietly slid down the form board. Here's who moved.

Turning it around

Pitchers whose form — our 0–100 score from ERA & WHIP — climbed most this week.

Joe Ryan led the climb, up ten points to a form of 75, with Logan Gilbert matching him at 75 after a five-point rise. Two Seattle names are trending the right way, which lines up with a Mariners rotation now fourth in starter ERA at 3.59.

Cooling on the mound

Of the strongest arms, the ones who shed the most form this week.

Logan Webb took the sharpest fall, dropping 13 points to a 59, with Drew Rasmussen down 12 to 74 and Cristopher Sánchez off 10 to 73. All three are still solid arms; this is a rough patch, not a collapse.

Hot at the plate

The week's hottest hitters — top OPS over the last 7 days (min at-bats), with their game line.

Tyler Tolbert was absurd, 13-for-19 with a 1.737 OPS for the week. Heriberto Hernández wasn't far off at 1.667 with four homers, and James Wood kept his month rolling, three more shots and six RBI in six games.

Cooling off

Hitters whose bat cooled most this week — shown with their 7-day line.

Bryce Harper had the quiet week, 1-for-20 across six games, his season OPS off 36 points. Nick Kurtz and Brandon Marsh cooled by similar margins, the kind of slump that gets erased in a weekend.

Changing colors

Players who moved up or down a tier on our scale this week.

Pete Crow-Armstrong and Otto Lopez both climbed from above-average into the elite tier, the reward for a strong stretch at the plate. On the other side, Davis Martin, Michael Wacha and Tanner Bibee each slipped from above-average to average.
