Friday night is Dodgers left-hander Scott Kazmir's turn to demonstrate that he is postseason ready. In the second of four games against the Rockies, Kazmir will be opposing Rockies rookie righty Jon Gray, who is coming off a club-record 16 strikeouts in his last start, a home shutout victory over the Padres. But more important, it will be Kazmir's first appearance since Aug. 22 -- before he was shelved with thoracic spinal inflammation.
