Major League Baseball's new rule on home plate collisions is causing some confusion.
Houston Astros manager Bo Porter had a telephone conversation Wednesday with Hall of Fame manager Tony La Russa, currently a special assistant to baseball commissioner Bud Selig. Porter said La Russa told him the league intends to clarify its rule on blocking the plate, and how such calls are challenged and reviewed.
MLB spokesman Michael Teevan said he wasn't aware of any plans for a new memo.
Porter telephoned La Russa after Astros outfielder L.J. Hoes was called out at the plate on an infield grounder in the eighth inning of Tuesday's 5-2 loss.
