PITTSBURGH — Edwin Diaz drilled the first batter he faced with the first pitch he threw Saturday night — and soon the Mets’ worst nightmare was unfolding.
The two-run lead Diaz had been handed wasn’t safe, just as a sizable advantage an inning earlier had become tenuous in the hands of Seth Lugo.
This one ended with Kevin Pillar lunging into the left-field stands desperately trying to retrieve Jacob Stallings’ descending fly ball, but to no avail. Stallings’ walk-off grand slam sent the Mets to a stunning 9-7 loss to the Pirates at PNC Park.
“I couldn’t believe it when it cleared the fence,” said Diaz, who pointed skyward as the ball left the bat. “I thought it was a fly ball.”
The Mets, who led 6-0 in the eighth inning largely on the strength of a pair of two-run home runs by J.D. Davis, lost their third straight and fell to 2-4 against the last-place Pirates.
Wilmer Difo’s three-run homer against Lugo spearheaded the Pirates’ comeback in a five-run eighth. But Diaz, pitching for the first time since blowing a save against the Pirates last Sunday at Citi Field, had a two-run cushion as he took the mound in the ninth after Brandon Nimmo’s solo homer in the top of the inning.
“It’s tough, when you don’t have your day, to win the game,” Diaz said. “Two of the [last] three losses were with me and I have just got to stay positive. … Tomorrow is another day.”
Ke’Bryan Hayes was hit by a pitch to begin the winning rally and Bryan Reynolds walked. After getting an out, Diaz surrendered a single to John Nogowski off Jonathan Villar’s glove that loaded the bases. Gregory Polanco struck out, putting Diaz within one out of the save before Stallings ended it.
“[Diaz’s] slider wasn’t the good slider tonight, it was backing up, and the fastball command was scattered,” manager Luis Rojas said.
The loss came hours after the Mets placed Francisco Lindor on the 10-day injured list with a strained right oblique. Rojas noted that Lindor is among the players who has a calming effect on Diaz during tough times and that presence was perhaps missed.
“Francisco is a guy that gives him a lot of confidence,” Rojas said. “Francisco makes some visits to the mound and pumps him up and they have a really good relationship.”
Rojas defended his decision to stick with Lugo in the eighth to face Difo after the Pirates had already scored twice against the reliever. He said Lugo was “finding himself” in the inning and his pitch count was at 20. Rojas said he liked the matchup and noted that Lugo has been used in some of the Mets’ highest-leverage spots in recent weeks.
Lugo, who walked two and allowed three hits, never escaped the inning, as Aaron Loup entered to get the final out.
“We’ve got a lot of baseball left and one loss doesn’t define the team,” Lugo said.
Davis belted a two-run homer in the fourth and another in the sixth, giving rookie Tylor Megill run support in his most impressive performance since joining the Mets. The right-hander fired six shutout innings in which he allowed six hits and struck out two, dropping his ERA to 2.63.
Travis Blankenhorn, recalled from Triple-A Syracuse before the game to take Lindor’s roster spot, drove in a run with a pinch-hit double in the seventh. Jeff McNeil contributed an RBI single in the inning.
J.D. Davis’ initial blast of the night came after three futile innings in which base running and double plays were an issue. In the first, Nimmo was late retreating to first base on McNeil’s fly to center and was doubled up to end the inning. Dominic Smith grounded into a double play in the second and Pete Alonso hit into one in the third.
McNeil walked to open the fourth and Davis crushed Wil Crowe’s next pitch over the center-field fence for the Mets’ first homer in 20 innings. The Mets had blasted two in the first inning in the final game before the All-Star break, but then went silent for the remainder of that game and scored their only run Friday on a ground out.
