Rosario started in right field and went 1-for-3 with a stolen base and a run scored in Friday's 6-5 loss to Pittsburgh.
Rosario singled, stole a base and scored as part of the Reds' four-run fourth inning. It was the second straight start in right field for Rosario, who was claimed by Cincinnati last week. With Jake Fraley (knee) landing on the injured list Thursday, there could be more opportunities for Rosario.
