Brandon Belt opened the 18th inning with a double, and he slid home on Erik Kratz's bases-loaded ground ball one out later, giving the San Francisco Giants a 3-2 victory over the Colorado Rockies in a game that started on Friday night and ended on Saturday morning. The win was the Giants' second in two games in the four-game series and gave them their first winning streak of the season. Colorado, which led 2-0 but did not score in the final 14 innings, dropped its seventh straight.
