Semien went 2-for-4 with a solo home run in Thursday's 5-4 win over Seattle.
Semien belted his 21st home run as part of the Rangers' three-run eighth inning that wiped out the Mariners' lead. It was the second home run in as many days, and third in the last four contests, for Semien, who has hit safely in seven of the last eight games while going 11-for-34 (.324).
