The Indians are 21-9 following a 12th-inning victory over the Mariners on Thursday. That matches their best 30-game start in franchise history. The last time Cleveland won the World Series, in 1948, they started 21-9. "They're very resilient and they believe in themselves," manager Manny Acta said. "It's early, but the amount of times that we have done it late in the games, really kind of gives them confidence."
