Added Rosario: "It's just a dream come true."
Rosario, the Bend but don't break: Mets starter Seth Lugo was on the ropes early. The scoreboard sported a 3-0 lead for the home club with two outs in the first, Phillies catching prospect Jorge Alfaro at the plate and two more potential runs on base. But Lugo buckled down, even after falling behind 2-0, with three straight strikes and a dandy of a curveball on the outside corner that Alfaro swung over.
"For how many pitches I threw in the first few innings, it ended with a positive being able to pitch into the sixth," Lugo said.
"More than a teammate, I feel like he's my brother. The same excitement he's feeling, I'm feeling for him." -- Rosario, on Smith
With his third-inning blast, Cespedes became the seventh Cuban-born big leaguer to reach 150 career home runs. Rafael Palmeiro (569), Jose Canseco (462), Tony Perez (379), Tony Oliva (220), Minnie Minoso (186) and Kendrys Morales (183) are the others.
Rosario became the first Met whose first career homer broke a tie in the ninth inning or later since Jordany Valdespin in 2012. That homer also came against the Phillies.
Mets: Left-hander Steven Matz, who is 0-4 with an 11.03 ERA over his last six starts, will look to snap his losing streak when the Mets return to Citizens Bank Park for a 7:05 p.m. ET game Saturday. Matz has not won a decision since June 28.
Phillies: Right-hander Aaron Nola has been one of the best pitchers in baseball since late June. He is 5-2 with a 1.76 ERA in nine starts since June 22. It is the third-best ERA in the Major Leagues in that span. Only the Indians' Corey Kluber (1.74 ERA) and the Yankees' Sonny Gray (1.75 ERA) have been better.
