The Mets' Luis Severino prepared to “fight until the end” in NLDS Game 2.

PHILADELPHIA – Citizens Bank Park is easily one of the loudest ballparks in baseball, especially in the late season. The Mets got to experience it for the first time in Game 1 of the NL Division Series on Saturday – and did a great job, ending the game with a late-inning stunner and winning 6-2

Right-hander Luis Severino will take the ball for the Mets in Game 2. He, too, plans to eliminate all outside noise when he takes the mound on Sunday.

“I’m going to try to put the pitch com as high as possible so I can hear the pitches,” Severino joked. “I’ve been here before, it’s all about executing pitches. In the end, it doesn't matter how loud it is, if you make your pitches, you'll be good…For me, my focus is just to hit every time (Francisco Alvarez) gives me the glove to make a mark .”

Severino appeared shaky in four innings in Game 1 of the Wild Card Series against the Brewers, allowing four runs. But then a courageous offensive comeback in the top of the fifth inspired the 30-year-old starter. He returned to the mound to retire the next six consecutive batters, steadying the Mets' staff and giving a much-needed break to the bullpen, which was overloaded with six games in five days.

“I would say we have a chip on our shoulder that we have to go out there and fight to the end,” Severino said. “We weren’t the favorite to get into the playoffs and we weren’t the favorite to win. We know that. But we will compete every day.”

Severino made two starts against the Phillies during the regular season, allowing three runs in both innings in six innings. Phillies first baseman Bryce Harper accounted for all three runs in Severino's second start and hit two home runs with three RBIs.

The Mets executed their pitching plan almost perfectly in Game 1. While they used four arms out of the bullpen after starter Kodai Senga, they did without Edwin Díaz, who threw 39 pitches in 1 2/3 innings against the Brewers on Thursday.

They will also have a fully rested José Buttó, eager to make up for giving up two consecutive late-inning home runs against Milwaukee in Game 3 of the Wild Card Series. And Tylor Megill could be used in a long-inning situation if the need arises.

The Phillies will start left-hander Christopher Sanchez against the Mets. Sánchez went 11-9 with a 3.32 ERA and 153 strikeouts in 31 starts this season. In three starts against the Mets, Sánchez allowed six runs over 17 2/3 innings (3.06 ERA).

What is most striking about Sánchez is his separation between home and the street. In 17 home starts, he is 7-3 with a 2.21 ERA (27 earned runs in 110 innings). In 14 starts, he is 4-6 with a 5.02 ERA (40 earned runs in 71 2/3 innings).

“This is something I just can’t explain,” Sánchez said Saturday. “I just feel really comfortable here, and the fans give me the opportunity to feel comfortable at home and be a pitcher here.
