Pirates lose challenge of stolen base in seventh

Alcantara ruled safe at second; call stands following review

PITTSBURGH -- A steal of second by Chicago's Arismendy Alcantara in the seventh inning of Saturday night's game at PNC Park stood following a challenge by Pirates manager Clint Hurdle.

Following a leadoff single off Brandon Cumpton, Alcantara took off and second-base umpire Ted Barrett ruled that his head-first slide got him in ahead of catcher Russell Martin's throw to second baseman Neil Walker.

Hurdle challenged the call, which stood after review.

Alcantara subsequently advanced to third on a wild pitch and scored on Welington Castillo's sacrifice fly to extend the Cubs' lead to 4-0.
