The Royals’ facing-a-lefty lineup leaves a bit to be desired. The Royals are facing a left-hander today and the lineup shows what might be a problem for the team going forward, even if the rookies only continue to improve: they’re almost all left-handed hitters. Vinnie Pasquantino and Nicky Lopez will both get the night off (or at least most of the night off) because the Dodgers will start left-hander Andrew Heaney.
