NBA: The Washington Wizards have exercised the fourth-year option of $7.7 million on Otto Porter Jr.'s rookie-scale contract for the 2016-17 season, according to a person with knowledge of the situation. The No. 3 pick in the 2013 NBA draft, Porter projects as a key cog in the franchise's young core. Porter, 22, averaged just 19.4 minutes over 74 games in his second season. But the lanky 6-foot-9 Porter capitalized on more playing time in the playoffs, averaging 10 points and eight rebounds in 33.1 minutes.
