PHILADELPHIA — On yet another chilly April night in their ballpark, the Phillies stayed hot at home.

Odubel Herrera hit a go-ahead triple in the eighth inning to lift Philadelphia to a 2-1 victory over the Pittsburgh Pirates on Friday night.

Herrera, Cesar Hernandez, Carlos Santana and Maikel Franco each had two hits for the Phillies, who have won nine of 11 overall while improving to 7-1 at home. It is Philadelphia’s best start at home since it won seven of eight to begin the 1981 season.

“You can definitely feel a different vibe, a positive vibe,” Herrera said.

It didn’t start exactly that way this season in front of the Phillies faithful, who booed first-year manager Gabe Kapler during introductions before the home opener following some questionable moves on Philadelphia’s road trip to begin the season. But those boos quickly have turned to cheers as the Phillies have strung together one win after another at Citizens Bank Park, standing as the only NL team with just one loss at home.

“It’s incredibly gratifying to win at home,” Kapler said. “I believe playing here at home in Philly is a big competitive advantage for us.”

Luis Garcia (2-1) pitched a scoreless eighth inning, and Hector Neris blanked Pittsburgh in the ninth to earn his third save in four tries.

After Hernandez led off the eighth with a double and Santana grounded out, Herrera lined an 86-mph cutter from George Kontos (1-2) on a 1-2 count just inside the first-base bag to score Hernandez and give the Phillies a 2-1 lead.

“It felt really good,” Herrera said through an interpreter. “I have a plan and that’s to put the ball in play.”

Rhys Hoskins walked to put runners on first and third with one out before as bizarre a double play as you’ll see ended the inning. Kontos had Hoskins picked off, but first baseman Josh Bell threw home to get Herrera, who broke for the plate on the play. Hoskins then lost track of the outs and also was out on a caught stealing double play that was scored 1-3-4-2-5-8-7.

“We saw something we tried to exploit and the Pirates executed,” Kapler said. The manager added that he talked to Hoskins after the game and “we’re going to move on.”

The Pirates threatened in the ninth when Jordy Mercer doubled with one out, but David Freese popped out in the infield and Adam Frazier grounded out.

After a promising 11-3 start, Pittsburgh has dropped four of five.
