NEW YORK — Whatever this thing is that’s going on at Citi Field, causing the Phillies to lose nine in a row here to the Mets, manager Rob Thomson doesn’t really worry about it.

He doesn’t let negative thoughts enter his mind. Doesn’t think his team is doomed nor unable to compete with the Mets in their ballpark. He is more convincing than others when he states that, and before Wednesday’s series finale, he even had some evidence as to why he’s there.

“It’s tough but you’ve got to grind through it,” Thomson said. “I was looking at some of the Yankees’ stuff from when I was there. So, from ‘05 to ‘09, when we were in California against the Angels, we went 3-13. In ‘08 and ‘09, we were 0-6. Actually, we had lost eight in a row and we beat them in the ALCS. It’s one of those things. You’ve just got to fight through it.”

Maybe the Phillies have just the right person taking the mound in Game 3 against the Mets. Taijuan Walker had a couple of decent seasons for the Mets, so he’s used to their home field. More than that, though, he’s got the makeup that maybe a situation like this calls for, according to his manager.

“I’m happy for him, he put a lot of work in [last] offseason,” Thomson said of Walker. “Came in, velocity jumped up. Now it’s kind of settled in but it’s still more velocity than he had last year. The other stuff moves up just because of the velocity — the split, cutter’s been really good, the slider’s been really good.

“But I’m really happy for him because he went through some rough times last year and he’s fought through it. That’s the sign of a competitor, a grown man.

“It’s tough and he hasn’t complained, he’s done everything we’ve asked. He’s been a true professional while he’s doing it. I love him because you know that he’s going to prepare and you know nothing is going to scare him. He’s going to compete through thick and thin.”

Marsh sits

In the ever-changing world that is the outfield for the Phillies, Brandon Marsh was the odd-man out on Wednesday against the Mets’ right-handed rookie Nolan McLean.

“I’ve liked Casty’s (Nick Castellanos) at-bats the last couple of weeks,” Thomson said. “Marsh is in a little bit of a tailspin and (Harrison) Bader’s been hot, (Max) Kepler’s had good at-bats. Just give him the night. He’ll be back in there tomorrow.”

It’s another part of the continued platooning that has become the norm for Thomson. And changing things doesn’t seem to be in the plan anytime soon.

“A little bit of that (hot player), a little bit of history, a little bit of the pitcher’s stuff versus Casty hits velocity for the most part,” Thomson said. “So, it’s a combination of a lot of things, really. I’d like five guys hot. That’s what I’d like.”

In McLean, the Phillies are facing him for the first time. In his two games, he’s won both and allowed just six hits and two earned runs in 12 1/3 innings.

“He can really spin it,” Thomson said. “He’s got carry to his fastball. It’s heavy, he can spin it. For the most part he can throw strikes, but you still have to be patient with him. Yeah, he’s got good stuff. It’s tough because you can do all the film and all the machine work, you can set up his breaking ball to how it’s going to look in the game. But until you get out there, you really don’t know.”

Romano speaks

It was announced Tuesday that relief pitcher Jordan Romano was being placed on the injured list because of right middle finger inflammation. This came a day after he got tagged for four earned runs in an inning of work in a 13-3 loss Monday.

“This just popped up a few days ago,” Romano said. “It’s my middle finger. When I woke up (Monday) it was numb for a little bit, like four or five hours. We got it going, worked on it to where I felt comfortable throwing at least. Then after the game just feeling a little off a bit the next morning, too. Shut it down, run some tests on it, make sure everything’s good.”

Romano has struggled most of the season, posting an 8.23 ERA in 42 2/3 innings pitched this season. After three stellar seasons with Toronto, in which he made two All-Star teams, Romano made just 15 appearances last season and had arthroscopic surgery on his throwing elbow.

“My last pitch that inning was 97, so it’s kind of frustrating to me, too,” he said. “I know it’s in there. It could be a delivery thing, health thing. So, we’re just kind of running through it and then see how it goes throwing and hopefully be able to be consistent again.

“For sure more motivated to pitch. Just missing time absolutely sucks, I just wanted to be available, at least. Obviously, I wasn’t pitching well, but if there’s one thing I can do is at least be available. A little more motivation to pitch.”
