Walker on first, ball sharply grounded to Biggio at 2B, Walker was running to second, then stopped while Biggio held it, and had to throw to first to get out the hitter, then Walker ran to second and was easily safe. Why didn't Biggio go to second first, if Aram was running? Too far off the bag towards first. Walker was running and literally came to a dead stop before running after Biggio threw it.
