Toronto Blue Jays outfielder Jonatan Clase (knee) is starting in center field and is batting in the nine-hole for Toronto in Thursday's series finale against the visiting Arizona Diamondbacks and right-hander Ryne Nelson at Rogers Centre.

The Toronto Blue Jays lost center fielders Jonatan Clase and Myles Straw due to injuries within two innings Tuesday night against Arizona. Clase, who started in center, exited after being hit on the right knee by a pitch in the bottom of the fourth inning.
