Commissioner Bud Selig expects baseball to expand its playoffs this season. Players and owners have already agreed to add an additional wild-card team in each league, but are still deciding whether it would take effect this year or in 2013.

Prosecutors said they might call former baseball players Barry Bonds and Jose Canseco, current baseball commissioner Bud Selig and New York Yankees general manager Brian Cashman as witnesses in the Roger Clemens perjury case. The defence said it might call former Clemens teammates Paul O'Neill, Jorge Posada and Mike Stanton, and baseball writer Peter Gammons.
