First baseman Kevin Barker is the rarest of breeds in the Brewers' clubhouse: a homegrown product who rocketed through the system. A third-round draft choice out of Virginia Tech in 1996, Barker was the organization's minor league player of the year in '99 after hitting 23 homers and driving in 87 runs at Triple A Louisville. Called up in August, he hit .282 with three home runs in 38 games-enough for the Brewers to hand Barker, 24, the starting job this spring over veteran Sean Berry. "Kevin's a tremendously hard worker, a throwback," says manager Davey Lopes. "He just has to be careful not to pressure himself to hit for power up here. He's improved at every level. The home runs will come."
