MIAMI — Giancarlo Stanton needed all of his considerable strength to maintain a stoic expression after he overcame his own baserunning blunder by crawling back to third base.
When Stanton scored moments later and reached the dugout, he finally allowed himself a big grin.
The Miami Marlins were a laughingstock for the first two weeks of the season, but they’re all smiles now. Adeiny Hechavarria hit a bases-loaded triple after a botched rundown saved Stanton and kept the inning alive, and Miami completed its first three-game sweep of the Washington Nationals since May 2012 by winning, 6-2, on Sunday.
