The Seattle Mariners and Kansas City Royals clash again tonight in Game 2 of a four-game AL West showdown at T-Mobile Park. The Royals are looking to stop the bleeding after a rough stretch of games, while the Mariners aim to maintain momentum after a strong recovery in the second half of June.

Kansas City continues to struggle at the plate, which has been the story of their season recently. The Royals posted just a .665 OPS in June — a mark that ranks third-worst in all of Major League Baseball, ahead of only Cleveland and Chicago (White Sox).

Their offensive woes were on full display Sunday afternoon in a 5-1 home loss to the Los Angeles Dodgers, and again in the series opener against Seattle, where they managed just two runs in a 6-2 defeat. Despite flashes of promise earlier in the year, the Royals appear stuck in a midsummer slump, especially on the offensive end.

Seattle, on the other hand, has begun to pull things together after a slow start to June. The Mariners opened the month with a dismal 2-8 record, but quickly rebounded, going 11-6 from June 13 forward.

That turnaround has helped them stay above the .500 mark and remain in the chase in the AL West, though they still trail division-leading Houston by six games. Their latest victory came in dramatic fashion — a 12-inning road win over the Texas Rangers on Sunday, 6-4, showcasing their resilience and improving bullpen.

Our Seattle Mariners vs Kansas City Royals Prediction

On the mound for Kansas City will be veteran right-hander Michael Lorenzen, making his 17th start of the 2025 campaign. Lorenzen holds a 4-8 record and 4.91 ERA with 73 strikeouts over 88 innings. He struggled in his last appearance against Tampa Bay, allowing four earned runs across 5.2 innings in a losing effort.

Seattle counters with Emerson Hancock, a young righty making just his sixth start of the year. Hancock enters with a 1-3 record and 5.30 ERA, though much of that damage came from a brutal outing against the Cubs where he surrendered nine earned runs. He looked much better in his most recent appearance, limiting the Twins to two earned runs in five innings before Seattle’s bullpen collapsed in a 10-1 loss.

Historically, the Mariners have dominated this matchup, going 10-4 against the Royals since 2023 and 6-1 at home during that span. Given both teams’ inconsistent offense and suspect bullpens, this game could shape up to be a low-scoring affair, especially if the starting pitchers can settle in early. Our prediction for Seattle Mariners vs. KC Royals: Mariners to win.
