How does that country song about old fogies reclaiming former greatness go?

Oh yeah, “I ain’t as good as I once was, but I’m as good once as I ever was.”

That could’ve been Andruw Jones’ theme song yesterday. The older-than-his-age-implies 34-year-old has been an afterthought this season, but yesterday he went 2-for-3 with a walk, two RBIs and a run scored in the Yankees’ 7-5 victory over the A’s on another sweltering afternoon in The Bronx.

BOX SCORE

Jones, batting .218, is not nearly as good as he once was as a perennial 30-homer, 100-RBI guy for the Braves. But he got a rare start in left field in place of Brett Gardner because Oakland started left-hander Gio Gonzalez, and Jones made the most of it.

“I know when I’m gonna play and I know when I’m in the lineup, so I just have to be prepared,” Jones said.

Jones looked more like his five-time All-Star former self than he has most of the season.

He drove in the Yankees’ first run in the second with a single to left-center that cut an early deficit to 2-1. He walked in the fourth and scored on an Eduardo Nunez double that gave the Yankees a 3-2 lead. Then he singled home Mark Teixeira in the fifth for his second RBI, and grounded out in the seventh.

As the song goes, “Now my body says ‘You can’t do this boy,’ but my pride says ‘oh yes you can.’ “

Jones’ pride did the talking yesterday.

“I know it’s tough, but you can’t make excuses,” Jones said. “Just go out there and get the job done. And I think that’s why they brought you here. When you sign the contract you know what the job’s gonna be and just gotta go out there and produce.”

Toby Keith would be proud.
