He's made his mark on the game.

And he's done it in a few different places.

Most notably, Bobby Kielty made an impression during his four years with the Oakland Athletics, where his popular hairstyles made him a fan favorite.

His last at-bat in the majors came in 2007, when he hit a home run for the Boston Red Sox in the deciding Game 4 of the World Series.

Surely, that would be a nice way to end his major league career, right?

"On one note it'd be great and on another it was a bummer in the sense that it was my last at-bat," Kielty said Tuesday following his first batting practice as a member of the York Revolution. "You feel like you have a lot left in the tank. I kind of would rather go out knowing I can't play anymore. That's how I feel."

Now 35, Kielty understands his time in baseball might soon come to an end. But he still feels like he can play at a high level. He might be doing so right now, if not for a few injuries since 2007.

The outfielder admits they may have played a role in him now being with York, where he'll compete in an independent league for the first time in his nine-year pro career.

Though he likely won't see game action until later in the week, the switch-hitting Kielty should be a much-needed shot in the arm for the Revs' offense. York is at or near the bottom of the Atlantic League in many offensive categories.

Kielty has played in 599 career major league games for Minnesota, Toronto, Oakland and Boston between 2001 and 2007. In the majors, he's accumulated 53 home runs and 253 RBIs, with a .254 average.

Injuries: Kielty underwent surgery to his left meniscus in 2007 and his left wrist in 2008. He still saw limited action both seasons.

It would be surgery to his right knee in 2009 that derailed his pro career. He needed it after injuring his knee during a play early in the 2009 season with the New York Mets' Class AAA Buffalo team. Kielty would miss the rest of the 2009 season and the entire 2010 season.

He returned to the game in 2011, spending most of the season with the San Diego Padres' Class AAA Tucson club, where batted .289 with seven homers and 28 RBIs in 62 games.

"I feel pretty good. Last year I probably wasn't 100 percent. This year I feel better than last year. Time has definitely helped me out," Kielty said.

'Ronnie Mac:' Kielty already has made a good impression on Revs' skipper Andy Etchebarren, having previously played for him 11 years ago in the Dominican Republic.

He might gain popularity with Revolution fans with his crazy hairstyles, just like he did with the Oakland Athletics' fans from 2004 to 2007.

A's fans nicknamed Kielty "Ronnie Mac" thanks to a wild hairstyle similar to Ronald McDonald's, the primary mascot for fast-food chain McDonald's.

"I remember I cut it and they were (mad) about it and were chanting at me 'Ronnie Mac we want your 'fro back,'" Kielty said.

Kielty's hair is short right now, but he plans on growing it out.

His main plan, though, will be showing big league clubs he's healthy enough and good enough to deserve another opportunity.

"It's certainly not about the money," he said. "I love the game. I love playing. I feel like I can still play. So, you're here because you want to try to get another shot."
