Each of the San Francisco Giants walked back onto the field after the final out and gathered near the pitching mound to offer their gratitude. What a drastically different encore than a year ago. No follow-up postseason run for the defending World Series champions to provide an extra month of thrilling baseball for the Bay Area. Kevin Kouzmanoff had three hits and drove in two runs, and the Colorado Rockies sent the Giants into an early offseason, beating San Francisco 6-3 on Wednesday.
