ST. LOUIS -- Ten key matchups in the AL and NL Championship Series that begin Friday and Saturday, respectively:

1. The Orioles vs. the Kansas City running game: This is like a steel-cage match within the main event. The Royals have run aggressively in the postseason, with 12 stolen bases in 13 attempts, including seven in their wild-card game against Oakland. Terrance Gore and Jarrod Dyson are setting new standards for brazenness.

But the Orioles are excellent at controlling the running game, and with the layoff before the start of the ALCS on Friday, you can bet O's manager Buck Showalter and his staff are preparing for the Royals' roadrunners. They already have some great countermeasures in place, such as:

Chris Tillman: Nobody steals against him because he delivers his pitches to the plate so quickly. Opponents have tried to steal 13 times on him over the past two years and have been successful twice. To repeat, that's two steals in 13 attempts.

Caleb Joseph: The catcher has a great arm, and during the season he threw out 23 of 57 baserunners.

Wei-Yin Chen: He has allowed just nine steals (in 13 tries) over the past two years.

The Royals' best chances may come against the Baltimore bullpen, using Gore and Dyson. Teams try to run on Darren O'Day because of his unconventional delivery (10 steals in 15 attempts over the past two seasons), and there have been only six attempts over the past two years against Andrew Miller (with four steals).

No team stole more bases than the Royals did during the regular season, while only seven teams allowed fewer steals than Baltimore.
