PHOENIX -- Chris Herrmann led off the 11th inning with a home run to left-center field off Rafael Montero as the D-backs walked off the Mets, 5-4, on Wednesday afternoon at Chase Field.
It was the first walk-off homer of Herrmann's career.
"I don't think there's anything that compares to hitting a walk-off home run," Herrmann said. "It's something you dreamed about as a little kid when you're a little kid, 6 years old playing out in the cul-de-sac hitting tennis balls."
The loss was the seventh straight for the Mets as the D-backs swept the three-game series and finished their nine-game homestand with a 6-3 mark. The Mets dropped all six games of their road trip through Milwaukee and Phoenix, making it their first winless trip of at least that length in 18 years.
"Losing can be as contagious as winning," manager Terry Collins said. "We're going to turn this around."

MOMENTS THAT MATTERED
Couldn't get him in: The Mets managed to get a one-out single by pinch-hitter Curtis Granderson off D-backs closer Fernando Rodney in the ninth. Jose Reyes, who had delivered an RBI double earlier in the game, flew out and after Granderson stole second, Michael Conforto grounded out to end the threat. Overall, the D-backs bullpen threw five scoreless innings.
"Overall I thought today was just a great game for everybody," Herrmann said. "Our pitchers came out and pitched well and gave the offensive players a chance to win the game for them."

Tomas stays hot: One night after his home run proved to be the difference in the game, Yasmany Tomas once again came up big in a clutch situation. This time it was a two-out double to left-center in the seventh that scored Paul Goldschmidt and tied the game at 4. The hit came off Robert Gsellman, a starting pitcher whose rotation turn the Mets skipped due to his recent struggles.
"It's a little different, but I still take the mound the same way as I always do," Gsellman said. "I'll be fine."
QUOTABLE
"I'm not going to put my head between my legs and feel sorry for myself. That doesn't [fly] here." -- Collins, on the Mets' seven-game losing streak

BABY STEPS
Mets starter Matt Harvey gave up fewer than five runs for the first time in four outings, settling down after some early struggles to hold the D-backs scoreless in the fourth and fifth innings. But Harvey did not string together a clean inning the entire afternoon, putting each of the first four leadoff men he faced on base. He allowed three runs in total, decreasing his ERA to 5.56.
"Obviously if I could go back and change a couple pitches, I would," Harvey said, focusing on a mechanical tweak he made between starts. "But overall, I felt much better today, and probably the best I've felt in two years. It's definitely a positive."
WHAT'S NEXT
Mets: Following an off day Thursday, the Mets will return to Citi Field hoping to put their nightmarish road trip behind them. Collins will match Davey Johnson as the longest-tenured manager in Mets history when the club hosts the Angels in Friday's opener of a three-game series, with Jacob deGrom opposing fellow right-hander Ricky Nolasco in the 7:10 p.m. ET game.
D-backs: After taking Thursday off, the D-backs will open a three-game series with the Padres on Friday at 7:10 p.m. MST. Taijuan Walker will start for the D-backs, and the last time he faced the Padres this year he allowed just two runs over eight innings.
