Rizzo also collected two doubles and scored three runs, while Luis Valbuena drove in a pair of runs for the Cubs, who snapped a two-game losing skid.
"I just feel very confident," Rizzo said. "If you're feeling confident at the plate, it makes a huge difference. I do feel good and I'm just gonna ride it out."
Chicago starter Travis Wood (6-5), who came in with a league-worst 8.04 ERA on the road, tossed a solid 6 2/3 innings, allowing three runs on nine hits and two walks.
Pirates top prospect Gregory Polanco made his long-awaited major league debut, going 1-for-5 with a single and a run scored. Andrew McCutchen smashed a two-run home run for the Pirates, who have dropped three of their last four.
