Michael Morse doubled in a run and added a Stars to a 6-2 win over the game exhibition series.
The MLB All-Stars have won each of the three games thus far, taking a 7-0 decision in the opener behind Curtis Granderson's grand slam and a 5-3 victory on Thursday. The final two games are scheduled for Saturday and Sunday.
Granderson and Yankee teammate Robinson Cano each singled in the first inning before Morse delivered a run-scoring double. Pablo Sandoval of the Giants then knocked in a run with a fielder's choice, before Florida's Emilio Bonifacio contributed an RBI single in the second for a 3-0 edge.
Morse, who was the Triple Crown winner for the Washington Nationals with team bests of 31 homers, 95 runs batted in and a .303 batting average, crushed a pitch over the center field wall for a 4-1 lead in the third.
Kansas City's Felipe Paulino started for the MLB stars and allowed a run in four innings.
