The Mets swept the Cardinals to win a sixth straight series, the first time the season started in franchise history.

ST. LOUIS. Six wins in a row at the start of the year? It will play.

Backed by Chris Bassit on Tuesday with six straight innings, the Mets beat the Cardinals for the second night in a row, this time 3-0, to secure the Amazons’ winning streak ahead of their final at Bush Stadium on Wednesday. For the first time in franchise history, the Mets won their first six series of a season.

A good serve will go a long way, and the Mets are reveling in that honor after 13 combined scoreless innings from their starters in the Cardinals’ first two games of the series. After Max Scherzer threw seven shutout innings in the team’s win on Monday, Bassitt followed him with six scoreless innings against the Cardinals hitters.

Bassitt gave up just two hits and recorded six strikeouts, three walks in 94 pitches. The right-hander has allowed at least one Cardinals batter to reach base in five of his six innings, but has managed to stop those runners every time. Luckily for Bassit, he teed off 12 of his last 14 batters to take the lead and gain the lead.

James McCann enjoyed a 3-of-4 game at the plate, hitting all fields as the Mets catcher looked to be attacking a bit. His first hit of the game, a 388-foot RBI double to the warning lane in center field, put the Mets on the board. His second hit was a single on the right and his third was another single, but this time on the left. McCann also hit his first home run of the season at Chase Field against the Diamondbacks last Friday.

Things escalated at the end of the serve after Pete Alonso was hit by Cody Wheatley’s helmet serve in the eighth round. Whitley’s 83-mph replacement hit Alonso right on the C-flap of his helmet, the second time this season a Mets first baseman was hit with a headshot. Alonso fell to the ground, but immediately got back up, and, visibly heated, the slugger seemed to exchange a few words with Wheatley before running to first base.

Mets manager Buck Showalter was the first to get out of the dugout, but he headed straight for first base to check on Alonso, who appeared to be fine and stayed in the game. The Mets players came off the bench and spilled onto the field, but remained on the grass behind the third base line, while the Cardinals remained in their dugout. The referees issued a warning to both teams, and when the situation calmed down, composure prevailed.

Alonso was one of three Met hitters on Tuesday. Dominic Smith and Starling Marte were also hurt by the serve, with Marte coming out in the ninth inning after warnings had already been issued. But the judges decided that there was no intent, so no one was expelled.

However, tensions in the Metz dugout were clearly high, as Scherzer was seen yelling at the Cardinals from his position on the top step of the railing. Marte’s hit on the pitch was the 18th time the Mets have been in practice this season, leading the major leagues. Alonso and Marte are tied for the lead in the big leagues with four fielding hits this season.
