MLB notebook: Cardinals' Wacha relegated to bullpen for NLDS
• Michael Wacha, who starred in the postseason as a rookie last fall, will be in the Cardinals' bullpen for the NL division series. “I was kind of expecting it,” Wacha said Wednesday after a 40-minute workout at Busch Stadium. Manager Mike Matheny said he'll go with Adam Wainwright, Lance Lynn, John Lackey and Shelby Miller the first four games against the Dodgers.
• Former Pirates manager Jim Tracy and ex-Bucs shortstop and coach Jay Bell are among candidates to be interviewed for the Diamondbacks' manager's position. Others identified by the team are Sandy Alomar Jr., Andy Green, Phil Nevin, Turner Ward and Joe McEwing.
• Teams will be limited to three trips to the mound by managers, coaches and catchers during a game, except for pitching changes, under experimental speedup rules to be used during the Arizona Fall League. Pitches also will be eliminated during intentional walks.
