Lukes went 1-for-4 with a solo home run in Thursday's win over the Rays.
The 32-year-old outfielder led off the fifth inning by lofting an Ian Seymour changeup into the right-field seats, putting the Blue Jays in the lead for good. Lukes has been struggling overall in August, slashing .185/.206/.277 across 19 games with two of his seven homers on the season and six of his 24 RBI.
