Brewers fans already embracing Greinke

MILWAUKEE -- The Zack Greinke trade is already a win for the Brewers, and he's three months away from throwing his first regular-season pitch.

The team said it added more than 1,500 new season seat account holders in the first three business days after a trade with the Royals for the 2009 American League Cy Young Award winner. That compares to 400 new account holders who signed on during the first two-plus months of the offseason.

"The response from fans has surpassed even our most optimistic expectations," Brewers executive vice president of business operations Rick Schlesinger said. "The excitement level has peaked in all areas of our business operations, from ticket sales to sponsors to retail sales."

Those retail sales were expected to spike after the first shipment of Zack Greinke name-and-number T-shirts arrived Wednesday afternoon at Miller Park.

Fans can also purchase Greinke T-shirts and jerseys online at the Brewers.com shop 24 hours a day.

Given the ticket demand, the team extended the sale of Holiday 4-Packs through midnight CT on Wednesday.  Holiday 4-Packs range in price from $60-$160 and are available in the field outfield box, loge infield box, club outfield box, terrace box, loge bleachers and terrace reserved seat locations.

Greinke is one of two new starters in the Brewers' pitching rotation. The team also traded with the Blue Jays for right-hander Shaun Marcum earlier this month, giving Milwaukee one of the National League's most formidable groups of starters.
