Chirinos will start Monday against the Royals, Josh Tolentino of The Athletic reports.
Chirinos has been used as both a starter and a long reliever -- pitching the bulk of the game after an opener -- so he should be able to pitch fairly deep into Monday's game. He's had good results this season, posting a 3.26 ERA, 0.83 WHIP and 19:4 K:BB across 19.1 innings.
