The first voice heard on WFAN radio and the only full-time female MLB color commentator, Suzyn Waldman talked to The Post’s Mollie Walker, prior to the Yankees’ deal for J.A. Happ, about the upcoming Red Sox series, the trade deadline and her advice for aspiring female commentators.

Q: In all of your years watching the Yankees-Red Sox rivalry, how does this season measure up?
A: Since my fandom goes back to both sides, nothing I think will ever match what actually went on in the ’70s, when the two teams absolutely despised each other. It’s different now. I think this is probably the first time since the middle of (the 2000s) when both teams were good at the same time. People try and make it a rivalry within the players and it’s not anymore. They all know each other.

Q: How do you predict the series to unfold, as well as the rest of the season for both teams?
A: I haven’t the slightest idea and anybody that tells you that they do is either making something up or lying. There is no way to predict baseball, as my partner (John Sterling) says all the time. You don’t know who is going to get hurt and you don’t know who is going to have a bad day. Baseball is every day. It’s like a soap opera unfolding. You want to enjoy that.

Q: What do you think the Yankees need to accomplish before the trade deadline?
A: They need to decide what kind of a team they actually have and work on making that part of it better. They’ve already addressed what I think is a big part in getting Zach Britton, which makes your bullpen all the much stronger. What that means to me is that they don’t think they’re going to get a front-line starter, and that’s OK. You see the success that Tampa Bay is having going the other way, bringing in bullpen people first and then their starters.

Q: What do you think about the Zach Britton trade?
A: I think it’s a tremendous addition to this team. He’s as good as it gets. From what I’ve been told by the Oriole people, he’ll fit right in. He doesn’t need to be the closer in the ninth inning because (Aroldis) Chapman is, but he can be if something happens. You’ve got four closers on that team, which I think is going to be tremendous.

Q: What advice do you have for other aspiring female commentators?
A: Don’t let anybody tell you no. And don’t try and be something you’re not. Everybody knows we did not play professional baseball, so find a way to talk about baseball from another angle. Don’t ever say, “This is how you should do it,” because the first thing someone will say is, “How does she know?” Just find a way, whether its humanizing people or analyzing what already happened or predicting what will happen, but don’t forget that you’ve got something to offer. And if you have something to offer, then don’t let anybody tell you not to do this.
