MILWAUKEE -- Brewers general manager Doug Melvin expressed his dissatisfaction with Greer Stadium while announcing a two-year extension of Milwaukee's player development contract with Triple-A Nashville.The new deal runs through the 2014 season. "We are pleased to extend our working agreement with the Sounds," Melvin said in a statement. "While the current facility and conditions are not totally satisfactory, we remain loyal and are very supportive of the ownership and Frank Ward in his continued efforts to get a much-needed new park. As general manager of a Major League franchise, I totally believe in this ownership, and if we can get the same support from the city, Nashville will be one of the most desirable franchises in Minor League baseball." The Brewers and Sounds have been affiliated since the start of the 2005 season. In eight seasons as a Brewers affiliate, Nashville has produced five winning records, made the playoffs three times and captured the 2005 Pacific Coast League title. In the regular season, the Sounds are 589-559 with Brewers farmhands. "We are pleased to continue our relationship with the Brewers," Ward said. "They are an organization that produces quality Major Leaguers through their Minor League system, and we are looking forward to watching Milwaukee's next tier of stars continue to develop in Music City." Hershel Greer Stadium opened in 1978 and is most identified by its guitar-shaped scoreboard. It is the oldest ballpark in the Pacific Coast League, and the Brewers and Sounds have lobbied Nashville city officials for a new stadium for years. When Ward's group bought the Sounds in 2009, it invested $2 million in the stadium, including improvements to the playing field and clubhouses. A city commission late last year conducted a study and recommended three potential stadium sites, but since then there has been no progress.
