SAN FRANCISCO — One club has won six elimination games in succession, four of them this year. The other has won five straight elimination games, all this year.

The Cardinals, the first-named club, and the San Francisco Giants, will meet in Game 7 of the National League championship series on Monday night at AT&T Park. One of them, for sure, will be eliminated, ending a streak.

Most seven-game series take on a classic quality about them at some point. But not this one. There hasn’t been a one-run game. After Sunday night’s 6-1 San Francisco win in Game 6, the runs difference between victory and defeat have been, in order, 2, 6, 2, 5, 5, 5.
