With the Red Sox sitting four games under .500 at 27-31 and riding a five-game losing streak, there’s no doubt the club is underachieving. But a disappointing first third of the season doesn’t mean manager Alex Cora is worried about getting fired.

Asked whether or not he was worried about job security on “WEEI Afternoons” with Andy Hart, Nick “Fitzy” Stevens and Ted Johnson, Cora said he was not. Cora received an extension to become the second-highest paid manager in major league history in July, signing a three-year deal in the $21-22 million range.

“No, not really,” Cora said Thursday. “From my end. I actually don’t ask coaches about that. I just ask them to do their best on a daily basis. But I can answer that question personally: No.”

Cora’s Red Sox were just swept in Milwaukee and are 10-16 in May. They are a staggering 6-15 in one-run games and suffered two such defeats at American Family Field this week.

“I feel like every day we go out there and we’re doing our best,” Cora continued. “It hasn’t happened for us. You look at the season and having conversations with some people this morning, I was like, ‘It’s a weird one, right?’ because it feels like you’re in every game but it’s not going your way.

“Just a tough stretch for us and for me as a manager and we’ve just got to be ready for tomorrow. We’ve got a big series coming up here in Atlanta. Hopefully, we can win two out of three or sweep it and get this bad taste out of our mouth.”

Cora is a favorite of ownership — and team president/CEO Sam Kennedy — and was thought to be given major security when he signed his deal last summer. As of now, despite Boston’s rocky start, there are no indications that the Red Sox are considering moving on from Cora. Chief baseball officer Craig Breslow, in just his second season running the baseball operations department, is also thought to be safe. Still, Boston has dug itself quite the hole early. As of Thursday’s off day, the Red Sox are 9½ games back in the American League East and 4½ games out of the wild card race and have an 18% chance to make the playoffs, according to FanGraphs.

“It’s not early,” Cora said. “I’ve been saying that… It’s the first third of the season we have played and we’re playing under .500. We have fallen behind a lot of games in the division. Obviously, there’s a lot of ways to make it to the playoffs. But if we’re going to talk about playoffs, we just have to play better. I think the first goal is to get back to .500 and start winning more games.”

In the immediate future, Cora said, the focus for the Red Sox needs to be on slowing things down and trying to win some games.

“There’s certain times in the season when things are going great that you can run freely and try to score from first, try to steal from second, steal bases and all that. Try to force plays,” he said. “In this case, if you look at it the last two or three weeks, every play matters. So slowing it down is the most important thing.”
