ST. LOUIS (AP) — Josh Staumont and Mike Mayers came within six outs of the first combined perfect game in major league history before Nolan Arenado lined a leadoff single in the eighth inning of the Kansas City Royals’ 7-0 win over the St. Louis Cardinals on Monday.

Staumont, a 29-year-old right-hander, served as the opener in a planned bullpen game for the Royals. He made his first major league start in his 167th appearance and struck out two in a 1-2-3 inning, throwing 14 pitches.

Mayers, a 31-year-old left-hander who pitched for the Cardinals from 2016-19, made his third appearance for the Royals this season after eight starts at Triple-A Omaha. He retired 18 consecutive batters before Arenado lined a 1-0 slider to left on his 72nd pitch. Willson Contreras followed with a single to center that stopped an 0 for 27 slide.

Taylor Clarke relieved and retired Brendan Donovan, Paul DeJong and Alex Burleson in order. Amir Garrett pitched a perfect ninth to finish a two-hitter and Kansas City’s second shutout this year.

St. Louis was shut out for the sixth time and has scored 13 runs in its last six games.

There have been 23 perfect games, the last by Seattle’s Félix Hernández against Tampa Bay on Aug. 15, 2012. All perfect games have been complete games.

Kansas City had not shut out the Cardinals since May 22, 2015, and had not blanked them in St. Louis since June 2, 2014.

In the opener of a two-game series, the Royals tied their season high with 16 hits and stranded 14 runners, one shy of their high.

Nicky Lopez matched his career high with four hits, and Nick Pratto and Vinnie Pasquantino had three each. Mike Massey hit a two-run homer and Bobby Witt Jr. added a solo homer.

Adam Wainwright (2-1) allowed three runs and nine hits in five innings for the Cardinals, playing their 18th game in a stretch of 19 days in a row. The Cardinals and the Royals have back-to-back days off Wednesday and Thursday.

Pasquantino hit an RBI double in the third. MJ Melendez hit a run-scoring triple in the fifth and scored on Freddy Fermin’s bunt down the first-base line for a 3-0 lead.

Pasquantino had an RBI single off Steven Matz in the eighth, and Witt and Massey homered in the ninth against Drew VerHagen.

NOOTBAR HURT

CF Lars Nootbar left after Pratto doubled leading off the third inning, appearing to pull up near the wall. Nootbar had slammed into the wall catching a Massey drive in the second. The Cardinals said Nootbar had back spasms.

TRAINER’S ROOM

Royals: RHP Brad Keller (right shoulder impingement syndrome) is progressing well after throwing a recent bullpen.

Cardinals: OF Dylan Carlson (left ankle sprain) has been taking swings from the right side. On Monday, he took swings left-handed. Once he is comfortable, he will have short rehab stint in the minors.

UP NEXT

RHP Zack Greinke (1-5, 4.55) starts Tuesday for the Royals and RHP Miles Mikolas (3-1, 4.23) for the Cardinals. Grienke is 13-7 with a 3.48 ERA against St. Louis. Mikolas pitched a four-hit shutout in his only game against the Royals on May 21, 2018.
