The Royals have recalled utilityman Whit Merrifield from Class AAA Omaha, the club announced on Tuesday afternoon.
He is expected to be in the lineup in right field when the Royals open a two-game series against the Giants on Tuesday night.
The Royals had an opening on their 25-man roster after optioning right-hander Jake Junis back to Omaha on Sunday evening.
Merrifield is batting .412 (14 for 34) with a .423 on-base percentage in nine games for Omaha. After a solid rookie debut in 2016, he was caught in a roster crunch during spring training.
