Wearing a white home jersey with red letters spelled out “Boston” across the front — a jersey inspired after the city rallied in the Red Sox's first game following the Boston Marathon bombings in 2013 — Buehler threw his first pitch at 11:11 a.m. on a chilly morning at Fenway Park.

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.”

The Red Sox have a chance to win their four-game series against the White Sox on Monday. The annual Patriots Day game begins at 11:10 a.m. Many fans often make a sports doubleheader of it by heading to the Kenmore Square area after the game at Fenway Park to watch runners complete the final miles of the Boston Marathon.
