Lukes is starting in center field and batting in the leadoff spot for Sunday's series finale against the Cardinals.
Lukes will start in the outfield for a fourth straight game Sunday, and the 30-year-old has been seeing more playing time while Daulton Varsho has been sidelined due to a sore shoulder. He's gone 3-for-10 with one triple and three runs scored over the first two games of the series against St. Louis. In 10 major-league appearances this season, Lukes is slashing .342/.395/.474 with four RBI across 43 plate appearances.
