Tony Sipp balked home the go-ahead run with the bases loaded in the seventh inning, giving the San Francisco Giants a 1-0 victory over the error-prone Cleveland Indians on Saturday for their fourth straight victory.
Sipp slightly flinched his left arm before even throwing a pitch to Emmanuel Burriss, allowing Miguel Tejada to score from third. There also were two errors in the inning by second baseman Cord Phelps that spoiled a strong start by Justin Masterson (5-6).
Matt Cain (7-4) pitched seven-plus innings of four-hit ball in another strong outing for San Francisco's right-hander. He struck out six and walked one to keep the offensively challenged Giants close.
Brian Wilson pitched a scoreless ninth for his 23rd save in 25 chances.
