Having already locked up their first American League East title since 1997 and home-field advantage in the ALDS, the Baltimore Orioles have begun preparing for the playoffs.

Buck Showalter plans to use a four-man rotation in the first round of the postseason, which will start Thursday, Oct. 2.

The way the rotation is set up for the final week of the regular season it appears as though the playoff rotation will be Chris Tillman, Miguel Gonzalez, Wei-Yin Chen and Bud Norris.
