Framber Valdez pitched seven scoreless innings and Josh Hader struck out Juan Soto with two on to save the Houston Astros' 3-1 win over the New York Mets on Thursday.

After loading the bases with nobody out in the ninth, Hader fanned backup catcher Hayden Senger in his first major league at-bat. Francisco Lindor's sacrifice fly made it 3-1, and there were runners on first and third when Hader struck out Soto swinging at a full-count slider wide of the zone for his 200th career save.

Soto singled and walked twice in his Mets debut after signing a record $765 million, 15-year contract as a free agent this offseason.

Making his fourth straight opening day start, Valdez (1-0) allowed four hits and struck out four.

Converted reliever Clay Holmes (0-1) yielded five hits and three runs — two earned — while walking four in 4 2/3 innings. Pitching on his 32nd birthday in his Mets debut, the former All-Star closer with the Yankees made his first big league start since making four as a rookie with Pittsburgh in 2018.

Jeremy Peña got hit by a pitch with one out in the second before touted prospect Cam Smith grounded an opposite-field single on the first pitch he saw in the majors. Brendan Rodgers walked to load the bases and Houston took a 1-0 lead when Jake Meyers grounded into a forceout that scored Peña.

Yainer Diaz hit an RBI single in a two-run third that extended the lead to 3-0.

The Mets debuted the No. 7 patches they’ll wear on their uniforms all season to remember Ed Kranepool, who died in September at 79. Kranepool spent his entire 18-year career with the Mets and was inducted into the team’s Hall of Fame in 1990.
