Tina Charles posted a double-double of 14 points and 10 rebounds to lead the U.S. National women’s basketball team over Croatia, 81-56, in their opening game of the 2012 Summer Olympics in London.

Croatia gave USA a tough time, keeping the score close throughout the first three quarters of the game. USA tried to press Croatia up court, but Croatia’s guards were too good beating the press, leading to easy layups at the basket. USA led by only three points at halftime

But the Americans eventually settled in on defense and ran away with the lead in the fourth quarter.

Angel McCoughtry, born in Baltimore, Md., followed Charles with 13 points on five-of-six shooting off the bench.

Though they won, USA shot only 44 percent from the field, 64 percent from the free-throw line and committed 20 turnovers; they’ll have to play better as competition grows stronger through the Olympics.
