Sorry, Steph. You too, Buster. Wait your turn, Jimmy G. The Oakland A’s are the biggest story in Bay Area sports.

That’s right. The Oakland mashers have been the best team in baseball for more than a month now, winning 27 of 34 games to storm back into the playoff race. They’ve also rekindled the fire in their fans, who are embracing a team many had given up on as penny-pinching losers.

Quite the contrary. The A’s are penny-pinching winners. And they’re doing it with panache.

Late-inning heroics. Lots of long balls. Clutch pitching — including Thursday’s bullpen heroics in the A’s sixth straight win, 7-6 over the Texas Rangers. Unbelievable results. It’s all become ridiculously routine for this latest edition of the Amazin’ A’s. Manager Bob Melvin knows he’s witnessing something special.

“The way we’re playing right now, if we’re in shouting distance, we have a chance to win,” Melvin said after Wednesday night’s amazing victory in Texas.

He’s right.

Minutes before he uttered those words, the A’s were down to their last strike against the Rangers, down a run in the ninth inning, when Oakland designated hitter Khris Davis swatted a two-run home run to put his team ahead. It was his sixth homer in four games, and came one day after the A’s had completed a legendary comeback win, besting the Rangers despite trailing by eight runs in the seventh inning.

This kind of thing doesn’t happen often in baseball.

During this remarkable stretch, Oakland has come from behind to win 17 times. A dozen times, the A’s have scored the go-ahead run in the eighth inning or later. Somewhere, Yogi Berra smiles. Turns out he was right: It ain’t over till it’s over.

(It should be noted that the baseball gods are a particularly cruel lot. Despite their hot streak, the A’s stand six games out of first place in the competitive American League West, chasing the first-place Houston Astros and second-place Seattle Mariners. A .500 Giants team, meanwhile, is only 5½ games out of first in the National League West.

How are the A’s doing it? Isn’t this a team that lost 87 games last year and was picked to be profoundly mediocre this season? Yup. But, like it has done in the past, developing young talent to avoid big contracts and sprinkling in some veterans, Oakland has stitched together an impressive group.

To analyze this group, you have to start with Davis, who has hit more home runs (112) than anyone in the major leagues since 2016. He may be the most under-the-radar slugger in baseball history, with few outside the 510 area code who would recognize him on BART. Despite his low profile, and general reluctance to talk or promote himself, Davis is clearly in the same league as Oakland sluggers who preceded him, including Reggie Jackson, Mark McGwire and (gulp) Jose Canseco. Simply put, the man rakes.

Beyond Davis, the A’s have a core group of youngsters that any team would covet. At the corners, the two Matts — Chapman (third base) and Olson (first base) — should provide a franchise foundation for years to come. Shortstop Marcus Semien has overcome some defensive issues from early in his career and appears rooted. Starting left-hander Sean Manaea, who threw a no-hitter earlier this season, anchors the rotation.

Offseason acquisition Stephen Piscotty came home to play for Oakland to be near his mother, who was battling ALS. She lost that battle, but not before she saw her son take the field for the green and gold. The right fielder has hit 14 homers this year, and has provided an emotional back-story to this run.

Seasoned veterans like second baseman Jed Lowrie and catcher Jonathan Lucroy have provided stability. The bullpen, anchored by All-Star closer Blake Treinen and recently bolstered by the acquisition of flame-throwing Jeurys Familia, has proved to be a team strength. (The A’s are 41-0 when leading after seven innings.)

Steering the entire operation is Melvin, who is among the best managers in the game.

It all adds up to a solid baseball team. And the A’s know it.

“It’s really exciting. This team has a never-say die attitude,” A’s President David Kaval said. “The feeling of confidence. The fans coming together. So much hard work has gone into this. It’s really great to see.

“It’s unbelievable the way the team is gelling. It’s incredible. Talking to Melvin, and some of the players, you can feel it in the clubhouse. They’re confident. They’re loose. They’re having fun. When you get on that track in baseball, look out.”

It will be interesting to see if the fans jump onto the bandwagon with both feet when the team returns home next week. Attendance figures were lousy for most of the first half of this season (the team drew less than 8,000 fans to the Coliseum seven times), but the A’s managed to set a franchise record last weekend (56,310) when they opened the normally covered seating atop the Coliseum’s Mt. Davis.

With the Raiders and Warriors both leaving town, the A’s are hoping to capitalize and become Oakland’s No. 1 — and only — big-league team. But can the fans trust the franchise to hold on to this talent? For once?

“I’ve been very clear since I came over a year and a half ago,” Kaval said. “We have a great group of young talented players. It’s really important for us to have those players for a long time. ... We want them contending for World Series championships here in Oakland.”

For that to happen, the team wants to build a new stadium, arguing that the additional revenue that comes with new digs would help the A’s pay to keep their homegrown stars. As it stands, the A’s are pursuing two sites — one at the Coliseum complex and the other at the Howard Terminal — and hope to have an economic deal in place by the end of the year.

“We’ve got a lot cooking. We’ve got to keep the momentum going,” Kaval said. “We want to have a nucleus of players to move forward into the new stadium. We want players that fans can buy their jersey.”

We’ll see how that all pans out. In the meantime, A’s fans find themselves atop the heap in Bay Area sports, a perch they haven’t enjoyed for quite some time.

The team comes home from this remarkable road trip Monday. They should receive a hero’s welcome.
