Replay's First Wrinkle of 2016 - Ball and Runner

It didn't take long for 2016's first issue with Replay Review to arise. With one out and runners at the corners in the bottom of the 2nd inning of the Opening Day Cardinals-Pirates game—the first regular season game played across MLB by time of day—Pirates batter Francisco Liriano (yes, a pitcher had the first RBI of the 2016 season) slugged a strong grounder between first and second base as Pirates baserunner R1 Jordy Mercer attempted to jump over the bounding batted ball.

After 1B Umpire Hunter Wendelstedt signaled that no contact had occurred between ball and runner, Cardinals Manager Mike Matheny called over Crew Chief Jerry Layne for a second opinion and request for Replay Review. Upon brief consultation with New York Replay, the umpires determined the play was not reviewable and the call, accordingly stood.

Replays (which, by rule, were not consulted) appear to indicate the batted ball did not touch R1 Mercer, Wendelstedt's call (which, by rule, was not reviewed) was correct.
