KANSAS CITY (Interstat) — Stephen Kolek pitched a complete-game shutout, scattering four hits and striking out two, as the Kansas City Royals defeated the Seattle Mariners 5-0 on Saturday, May 23, 2026, before 25,544 at Kauffman Stadium. Kolek, who improved to 3-0, allowed no walks and faced only 30 batters over nine innings, needing just 2 hours, 6 minutes to finish the game. George Kirby took the loss, dropping to 5-4 after allowing five runs – four earned – on nine hits over six innings. The Mariners fell to 25-28, while the Royals improved to 21-31. The game turned decisively in the bottom of the first inning, when the Royals scored three runs on a combination of base hits, a fielder’s choice and an error. Maikel Garcia led off the inning with a double to center field. Bobby Witt Jr. followed with a soft ground-ball single to third base, moving Garcia to third. Vinnie Pasquantino then reached on a fielder’s choice that scored Garcia, but the play also included a throwing error by second baseman Cole Young that allowed Witt to advance to second. Pasquantino was credited with a run batted in. After Salvador Perez grounded out, Carter Jensen grounded out to first base, plating Witt for the second run. Jac Caglianone then singled to right field, bringing home Pasquantino and giving the Royals a 3-0 lead. Isaac Collins struck out to end the inning, but the damage had been done. The Mariners threatened in the top of the second inning. Luke Raley led off with a single on a ground ball to second base, a play that was originally ruled an out but was overturned upon challenge by the Mariners. Cole Young followed with a line-drive single to right, advancing Raley to third. Dominic Canzone then grounded into a double play: first baseman Pasquantino threw to catcher Jensen, who tagged out Raley at home, and then relayed to third baseman Garcia to complete the unconventional twin killing. Canzone was out at first, and Young advanced to second but was stranded. The Royals escaped without damage. Kansas City added a run in the third inning. Witt singled to center, and Pasquantino followed with a single to center that sent Witt to second. Perez flew out to right, moving Witt to third. Jensen then lifted a sacrifice fly to left field, scoring Witt and extending the lead to 4-0. The Royals put the game away in the sixth inning. With one out, Jensen singled to right. Caglianone grounded out, moving Jensen to second. Collins then lined a single to center field that scored Jensen, giving Kansas City a 5-0 lead. A challenge by the Mariners on the tag play at the plate was upheld. Michael Massey followed with a single, but Kyle Isbel grounded out to end the inning. After the sixth, the Royals’ bullpen was not needed; Kolek retired the Mariners in order in the seventh, eighth and ninth innings. Seattle managed only one baserunner in the final three frames, a walk to Julio Rodriguez in the seventh that was immediately erased by a double play. The most critical sequence of the game occurred in the bottom of the first inning, when the Royals capitalized on a throwing error to break the game open. The Mariners had won the series opener Friday afternoon 2-0 behind a strong pitching performance, but Saturday’s contest was defined by the Royals’ early outburst and Kolek’s dominance. Seattle’s only consistent threat came in the second inning, but the double play that erased Raley at the plate sapped any momentum. After that, Kolek settled into a rhythm, retiring 11 straight batters at one point from the third inning through the sixth. He allowed just one hit after the second inning, a double by Raley in the eighth that was the only extra-base hit for the Mariners. Raley finished 3 for 3, accounting for three of Seattle’s four hits. He doubled in the eighth and singled in the second and fifth innings, but was stranded each time. The Mariners left only two runners on base in the entire game, a testament to Kolek’s control and the Royals’ defense. For Kansas City, Massey led the offense with two hits in four at-bats. Witt also had two hits and scored two runs. Jensen drove in two runs, one on a sacrifice fly and one on a single. Pasquantino drove in a run, and Collins and Caglianone each contributed one RBI. The game was played in a crisp 2:06, the fastest of the season for either team. The win snapped a four-game losing streak for the Royals and evened the four-game series at one game apiece. The teams will play the series finale Sunday afternoon. Interstat’s game simulator projected a final score of Seattle 4, Kansas City 1. Interstat’s ELO system gave Seattle a 53.90 percent probability to win. The Mariners were installed as a pregame favorite with a spread of minus-1.5. The total score of 5 went over the over-under line of 8.5.
