The Kansas City Royals blanked the Seattle Mariners 5–0 on May 23 at Kauffman Stadium in a pitching-dominated matchup that fell well short of the Vegas total of 1. Kansas City's offense manufactured five runs on nine hits despite posting a modest .688 OPS, while the Mariners managed just four hits and drew only one walk, finishing with a .685 OPS in their shutout loss. Seattle's pitching staff struck out four batters but surrendered nine hits and three earned runs, unable to contain Kansas City's modest but efficient offensive output. The Royals' defense was flawless with zero errors, supporting a pitching performance that limited damage despite allowing four hits. Both teams struggled offensively—the Mariners struck out just twice but couldn't generate any scoring opportunities, while Kansas City's four strikeouts reflected the overall lack of explosive action. This low-scoring affair underscores Seattle's offensive inconsistency as the team heads into the latter stages of May with a run-differential problem that could compound if the lineup doesn't find more consistent production.
