NEW YORK (AP) — Seattle forward Jordan Morris has been voted Major League Soccer's Rookie of the Year after scoring 12 goals in his first professional season.

The 21-year-old made his national team debut two years ago while still at Stanford.

He received an average of 45 percent of the vote in balloting by players, media and club management that was announced Thursday. He will miss Friday's World Cup qualifier against Mexico because of a hamstring injury.

Philadelphia right back Keegan Rosenberry was second at 31 percent, followed by New York City midfielder Jack Harrison at 15 percent.
