Lefty Doug Nikhazy, the 27th man for today’s doubleheader, will start the second game at 6:10 p.m. Nikhazy, who faces Walker Buehler, will be making his big league debut. The doubleheader was caused by Friday’s postponement because or rain and cold.

In his first career Patriots Day start, Red Sox righty Walker Buehler dominated on Monday morning against the White Sox.

BOSTON — In the estimation of his manager, no other Red Sox pitcher has a pre-game routine as detailed as Walker Buehler. “It doesn’t matter if it’s 7 (p.m.) or 11 o’clock,” said Alec Cora Monday morning. “He’s on-point. It’s not like it takes him a long time to get ready. But there’s a lot of moving parts throughout his process.”
