SEATTLE -- The A’s may have already played their final game at the Coliseum, but there is still a sense of pride inside that clubhouse in representing Oakland until the very end of the season.

Following what was his final home start last week against the Yankees, Joey Estes expressed his love and appreciation for Oakland and its fans, who showed up to support him every time he took the mound.

As the A’s took the field at T-Mobile Park in Seattle for the final night game of the Oakland era on Saturday, a storied 57-year chapter of baseball that began in 1968, it was fitting that Estes -- who dons No. 68 -- toed the rubber wearing the road gray uniform with “Oakland” displayed across his chest one last time in the penultimate game of the regular season, a 7-6 loss to the Mariners in 10 innings.

"It’s everything just to be able to wear it across my chest and wear it proudly,” Estes said. “Even though [Thursday] was the last game in Oakland, they still came out here all the way to Seattle to still come and support. That just shows the true heart that this fan base has."

A smattering of A’s fans was present throughout the stadium, some showing up early and lining up just behind the visiting dugout to take in the club’s batting practice and cheer on the green and gold, many of whom Estes has befriended since his arrival to the Majors last season.

"I’ve met so many fans that I consider family now,” Estes said. “Getting to know every single one of them, it’s just a good feeling to be a part of this. It’s not just a fan base, it’s a family. They really make you feel like that. I'll appreciate Oakland forever and I’ll continue to talk about Oakland."

Estes took a no-decision after allowing three runs on five hits and two walks with two strikeouts across five innings. In his first full season as a big leaguer, the 22-year-old rookie right-hander finished with a 5.01 ERA in 25 games (24 starts). His 127 2/3 innings pitched rank fifth most among American League rookies.

"When I talked to him after that last inning, he said ‘I’m going to do better,’” manager Mark Kotsay said. “I said, ‘Hey look, this is your first full season here getting your feet on the ground and there’s a lot we can learn from. You’ve given me your best every time you take the mound. You’re a competitor.’ There’s a will there to improve. I know he’s going to spend the offseason focused on that, and we’re going to support that and be prepared for him to come into Spring Training and take another step forward."

Estes demonstrated plenty of flashes of why the A’s were so high on him as a top prospect. He demonstrated super command throughout the year by issuing no more than two walks in 24 of his 25 appearances, even tossing a “Maddux” in his shutout of the Angels on July 3 at the Coliseum.

"I’m proud of myself for getting through all the ups and downs of being a Major League Baseball player,” Estes said. “I’m happy with where I’ve gotten, and I still have a lot of work to do. It makes me excited for next year just knowing that I still have a lot to prove."

The A’s drummed up some classic Oakland late-inning magic with a ninth-inning rally capped by a two-out, go-ahead three-run home run by Shea Langeliers -- his 29th of the year -- only to be foiled by a rare blown save by All-Star closer Mason Miller, who surrendered a game-tying homer to Luke Raley in the bottom of the ninth.

The A’s will have a lot to play for in Sunday’s series finale. In addition to it being their final time wearing the “Oakland” jerseys, finishing with round numbers is a theme. They would like to close out with their 70th win of the year, while Langeliers and Brent Rooker are both on the verge of personal milestones.

"We’ve continued to represent Oakland,” said Rooker, who sits at 39 homers after crushing a two-run blast in the fifth. “We’re going to continue to do our best to make that fan base proud and represent them in a way that they deserve.”
