HOUSTON (AP) _ Mike Moustakas homered in the 11th inning to lift the Kansas City Royals to a 6-4 win over the Houston Astros on Wednesday night.
Moustakas has been off to a tough start this season and was hitting .098 before his solo shot to the seats in right field off Jerome Williams (0-1) to lead off the 11th.
A small group of Royals fans stood and yelled `Moooooose' as he rounded the bases after his first homer this year.
Jarrod Dyson singled and added an insurance run on a fielder's choice.
Danny Duffy (1-0) pitched two scoreless innings for the win and Greg Holland allowed a hit and a walk in a scoreless 11th for his fifth save.
Jason Castro and Marc Krauss both had two-run home runs for the Astros. Heralded Houston prospect George Springer made his major league debut, batting second and playing right field.
The 24-year-old, who hit 37 homers combined in Double-A and Triple-A last season, singled and walked, but struck out with one out and a runner on first in the 11th.
