Johnny Cueto has his health but not his stuff. Cueto, who avoided Tommy John surgery but has lost some velocity, will try to regain some of his form Saturday when the Giants oppose Milwaukee in a 6:05 p.m. PT rematch. Having allowed three home runs to the A's in his last start, Cueto might be a trifle wary of the Brewers, who are tied for third among NL clubs in homers. Left-hander Jhoulys Chacin will start for Milwaukee.
