Matt Cain has never looked worse on a major league mound, although he didn't feel as bad as the final score suggested. Cain was rocked for nine runs, matching the most he has allowed in the big leagues, and Jose Peraza drove in a career-high four runs in the first four innings to lead the Cincinnati Reds over the San Francisco Giants 13-3 on Friday night. Cain (2-1), a 32-year-old veteran of 13 seasons, allowed 10 hits and threw 78 pitches in 3 1/3 innings.
