Garver went 1-for-4 with a solo home run in Friday's 2-0 win over the Athletics.
Garver's second-inning homer was all the run support Bryan Woo needed. Garver is up to 15 homers this year, including three over his last seven games. The 33-year-old has mostly had a disappointing season for the Mariners, posting a .172/.286/.341 slash line with 51 RBI, 37 runs scored and 17 doubles across 113 contests.
