SAN FRANCISCO -- Jeff Samardzija is going to prepare as if he might pitch a potential wild-card playoff game Monday and stay ready in case he might be needed sooner if San Franciscos season is on the line.The Giants wasted Samardzijas latest stellar start with a chance to grab momentum after a big offensive outburst a night earlier, yet instead the playoff-hopeful Giants ended up with a costly dud in a 2-0 loss to the Colorado Rockies on Wednesday night.As long as they know Im ready, thats all that counts, Samardzija said. ... This is the time of year, man, this feels great to be out there pitching when the weather turns a little bit and the season comes to an end. I always love being able to see the finish line and it always allows me to go a little harder. I enjoy staring down the tube when its about to be done and just let it all hang out. Hopefully we get a chance to do that here a handful more times.The bats had better be ready the rest of the way, too.Rockies right-hander Tyler Chatwood (12-9) struck out nine in eight innings and outdueled Samardzija (12-11), shutting down San Francisco a day after the Giants pounded 19 hits in a 12-3 win.San Francisco dropped 1 1/2 games behind the Mets for the top wild card and remained a game up on St. Louis for the second spot after the Cardinals lost to Cincinnati.In a game that began with a hovering mist above the field on a cool Bay Area night -- with first-pitch temperature 55 degrees -- Samardzija struck out a season-high 11 in six-plus innings of his final regular season start.

Chatwoods been tough on us. He was good tonight. We just couldnt figure him out. We had a runner on second base one time through eight innings. Thats going to work.
