Seattle Mariners Set For Important Series with History-Making Rangers Rotation

When we think of the Texas Rangers, we think of offense. Go back to 2023, when the Rangers won the World Series, and the organization was driven by the bats, from Corey Seager to Marcus Semien to Adolis Garcia to Mtich Garver to a young Evan Carter in the playoffs.

This year, the Rangers have been fueled by their elite pitching staff, and really, their elite starting rotation, which is making history.

Per Rangers PR:

The Rangers’ pitching staff has recorded a 3.25 ERA through 81 games, best in the A.L. this year and the 2nd-lowest staff ERA in WSH/TEX franchise history (beg. 1961) at the season’s midpoint, behind only the 1983 club (3.19).

Additionally, Texas’ starting rotation leads the A.L. with a 3.22 ERA, also the 2nd-best mark in franchise history through 81 games to the 1983 Rangers (3.08).

That means that the Seattle Mariners will have a tough task in front of them when they head to Texas this weekend for a three-game series with the Rangers. Seattle is 1.5 games ahead of the Rangers in the battle for the third wild card spot (41-39), but they have an inconsistent offense that just scored one run in the final two games of a four-game series with the Minnesota Twins.

The Mariners luck out in the sense that Jacob deGrom isn't due to pitch in this series, but they will see Nathan Eovaldi (4-3, 1.56 ERA) in the opener of the series. The Rangers haven't announced the rest of the weekend probables as they bring Eovaldi back from the injured list.

First pitch of the series opener is set for 8:05 p.m. ET.
