PHOENIX -- The A's popular "Green Collar Baseball" marketing campaign is back for a second season, with several players lending their commercial acting talents to ensure it avoids a sophomore slump.

The A's, along with advertising agency Hub Strategy, introduced this year's version of the award-winning campaign on Saturday. Jim Leahey, the A's vice president of sales and marketing, was joined by Hub's creative director and founder, DJ O'Neil, at Phoenix Municipal Stadium to put in motion a concept that again highlights the enthusiasm and aggressiveness surrounding a rather young Oakland team.

"It's been about the idea that the A's are a young team and they make up for their youth with an extra measure of hustle and creativity, effort and fun," O'Neil said. "It's baseball, so it should be fun. It was really pretty successful last year, and everyone seemed to like it, so we thought, 'Let's extend the campaign this year.'"
