Turner out after going from 1st to 2nd on walk

WASHINGTON -- An unusual play unfolded in the first inning of the Nationals' 11-8 loss to the Cardinals on Tuesday at Nationals Park, as Trea Turner was called out after advancing on the bases following a walk to Bryce Harper.
After drawing a walk of his own from Cardinals right-hander John Gant, Turner attempted to steal second base on a 3-2 pitch to Harper. Although Harper took the pitch for ball four, Yadier Molina threw down to second base and shortstop Paul DeJong held the tag on Turner as his foot came off the base.
Turner was initially ruled safe on the field, prompting the Cardinals to challenge. A walk is not a dead ball, so Turner is only allowed to advance 90 feet after Harper's walk. After a quick review, the call on the field was overturned with Turner ruled out trying to advance to third base.
