There will be time for sleep on Monday, when the Baltimore Orioles have an off day, and Manny Machado needs it. He estimates that he had about 12 hours of sleep in the first 72 hours after he was called up to the big leagues, with the adrenaline rush, the phone calls and text messages fueling him. When a young player is summoned to the big leagues, the entire baseball community shares the joy.

The first to call was Yonder Alonso, a close friend who happens to also be the first baseman for the San Diego Padres, and Alonso was screaming. "See?" Machado remembers him yelling. "Hard work pays off! You worked your ass off!"

When Machado went out for his pregame sprints in his Thursday debut, he crossed paths with Eric Hosmer and Mike Moustakas of the Kansas City Royals, and they had hugs for him. "Stay hungry and just do you," Hosmer said to him. "Don't try to do too much."

Machado walked up to the plate for his first major league at-bat, and Royals catcher Salvador Perez greeted him. "Congratulations," Perez said.

"Welcome to the big leagues," said home plate umpire Tim Tschida.
