NEW YORK — Andruw Monasterio and Masataka Yoshida hit two-run homers as the surging Boston Red Sox extended their winning streak to eight games with a 4-0 victory over the New York Mets on Saturday.

Boston is on its longest winning streak since taking 10 in a row from July 4-13 last year. The Red Sox have won 13 of 15.

The Red Sox arrived late for Friday’s series opener after flight trouble stranded them in Chicago for nearly 24 hours. Boston poked fun at the ordeal by sporting white T-shirts that read “Show and Go Airlines, See You at 4:15.”

Following a leadoff walk to Caleb Durbin in the fourth, Monasterio put the Red Sox ahead by hitting a fastball from Freddy Peralta (5-8) into the left-field seats.

Durbin singled off Tobias Myers starting the eighth and Yoshida lifted a 1-0 cutter into the right-field seats.

Eduardo Rivera, promoted from Triple-A Worcester, started with 3 1/3 hitless innings in his first big league start before allowing Jorge Polanco’s single on his final pitch.

Greg Weissert and Jovani Moran (2-2) combined to pitch the next 2 2/3 innings and Justin Slaten escaped a bases-loaded jam in the seventh with a called third strike on rookie A.J. Ewing, who lost an ABS challenge.

Danny Coulombe ended the eighth by getting Polanco to hit a double-play grounder and then finished Boston’s AL-leading ninth shutout.

Peralta allowed two runs, three hits and five walks in 4 1/3 innings. He is 0-3 with a 7.59 ERA in his last five starts.

New York (40-56) went 0 for 8 with runners in scoring position for the second straight day. The Mets were blanked for the ninth time and were held to three hits or fewer for the eighth time.

Left-hander Payton Tolle (5-6, 3.14 ERA) starts Sunday for Boston. Rookie right-hander Zach Thornton (0-1, 4.35) will likely pitch behind an opener for the Mets.
