HOUSTON — All has been relatively quiet on the Yankees’ trade front as Monday’s non-waiver trade deadline approaches, but manager Joe Girardi on Wednesday said the club might not be done making moves — just not the ones everyone seems to expect in terms of cleaning house.

Asked if he senses more deals coming, Girardi said, “Yeah, I think it’s a possibility. I know everyone is going to say, ‘subtract,’ but Brian said, ‘We’re not saying that we’re just subtracting. We could be adding, too.’ I think that’s a possibility.”

A manager’s job is tied to the win-loss column, and that could put Girardi in an uncomfortable spot if the organization’s focus is on the future.

“I don’t let it bother me,” Girardi said. “I manage every day the same way to win the game. And you manage games where you don’t put players in jeopardy of getting hurt, too. That’s not going to change.”

Nova drawing interest

Righthander Ivan Nova (7-5), who is scheduled to start Friday night at Tampa Bay, is drawing considerable interest on the trade market, but he’s trying to ignore it.

“I’m not the type of guy that listens to stuff,” Nova said. “My only job is trying to get the team back in the fight, trying to go out there and put out a good game for the team and, hopefully, get a win. We have played a lot better after the All-Star break. There’s a lot of baseball left, and I think the only focus is just to keep winning.”

Day off for Miller, Betances

Neither closer Andrew Miller nor eighth-inning setup man Dellin Betances were available Wednesday night after working the first two games of the Astros series. Girardi used Adam Warren for the first time since he was reacquired in the trade for Aroldis Chapman on Monday, and he threw a scoreless sixth inning . . . Luis Severino, who was 0-6 as a starter with a 7.46 ERA but was recalled on Monday, was impressive in two scoreless innings with two strikeouts and one walk. “It was his explosiveness,” catcher Brian McCann said. “He got ahead, and he put guys away with two strikes. The ball was exploding out of his hand tonight.”
