Kelly gave up four runs on seven hits in five innings.
NOTES: St. Louis is the first team in major league history to have four rookie pitchers make at least four appearances in one postseason -- RHP Carlos Martinez (six), RHP Seth Maness (five), RHP Trevor Rosenthal (five) and RHP Kevin Siegrist (five). The Cardinals' bullpen opened the postseason with an LCS-record 15 1/3 consecutive scoreless innings before Ellis' home run off RHP Edward Mujica in the seventh inning. ... Dodgers LHP Clayton Kershaw, the NL Cy Young Award favorite, will oppose Cardinals rookie RHP Michael Wacha in Game 6, a rematch of Wacha's 1-0 victory in Game 2 last Saturday. Kershaw is 1-1 with an 0.47 ERA in three postseason starts this year. Wacha is 2-0 with a 0.64 ERA in two playoff starts.
