Hunter Pence is back, and the same could be said of the San Francisco Giants' offense. They may not need to do much with Chris Heston getting the ball. Heston aims to build on his first complete game - and the only one by a member of the Giants - as the club goes for its longest road winning streak over the Cincinnati Reds in nearly a decade Sunday. San Francisco (19-18) ranks near the bottom of the majors with 26 homers and 3.68 runs per game, but the team may be capable of changing that with Pence returning to action.
