Washington Nationals manager Dave Martinez reportedly underwent a cardiac catheterization after experiencing chest pains during Sunday's win over the Atlanta Braves.
Mark Zuckerman of MASN Sports reported the news, noting Nationals general manager Mike Rizzo deemed it a "little minor procedure" while revealing Martinez seemed "upbeat." According to Zuckerman, Martinez will remain in the nation's capital as the Nationals prepare for a three-game series in St. Louis that begins Monday.
