The Brewers are looking to add another piece or two, but appear unwilling to part with any of their top prospects. "We are looking to add some pieces here," team owner Mark Attanasio said. "But there's no guarantee of that, so these guys have to get the job done here. "And we have confidence they can. We wouldn't be looking ahead (to a trade) if we didn't think this was a playoff-caliber team." Milwaukee entered their game against San Francisco on Saturday night trailing St. Louis by 1/2 game for the lead in the NL Central. "Within limits, the payroll can expand depending on the caliber of the player involved," Attanasio said. "With our fan support, we're on the upper end of what I thought we could do here. "We're actively looking at some guys, but one of the (byproducts) of the wild-card system is there's a lot of teams still in contention."
