McKinstry went 1-for-4 with a two-run home run in Thursday's 4-1 win over the Athletics.
McKinstry provided Detroit with some breathing room in the fifth inning, launching a two-run homer off Jack Perkins for his fourth long ball of the season. Over his last 11 games, the infielder is batting .295 (13-for-44) while raising his season batting average by 25 points during that stretch.
