The A’s, who improved to 30-13 in day games this year, took a 1-0 lead in the third inning on Daric Barton’s sacrifice fly.

After the Rangers tied it in the bottom of the third, Oakland regained the lead in the fourth with Ellis’ solo shot.

The A’s extended their lead with two runs in the fifth and three more in the sixth, highlighted by Kouzmanoff’s solo blast to lead off the inning.
