Mateo joined the Orioles' lineup on Sunday while starting second baseman Jordan Westburg dealt with an illness, but will move back to the bench today with Westburg available.

Mateo is struggling to find playing time this year in the Orioles' stacked lineup, despite posting a career-best .733 OPS in his first 39 plate appearances. He's still making his presence felt with 4 stolen bases on the season, but will likely need an injury or a trade to become a reliable fantasy contributor again this season.
