Kemp will start in left field and bat ninth in the order Sunday against the Blue Jays, Jake Kaplan of the Houston Chronicle reports.
Kemp had an unremarkable stint with the Astros earlier this summer, but has thrived since heading back to Triple-A Fresno and rejoining the big club Aug. 7. In seven appearances (four starts) during that time, Kemp has gone 6-for-21 with five runs and a stolen base. The Astros recently cleared out some of their outfield clutter by designating Carlos Gomez for assignment, and with Jake Marisnick day-to-day with a groin injury, opportunities could remain available for Kemp for the foreseeable future.
