FORT MYERS, Fla. — At approximately the same time the Red Sox’ charter flight touched down in Tokyo yesterday afternoon, Jon Lester was making his final spring training start at the team’s minor-league complex.

The Red Sox left-hander worked five perfect innings in a Double-A intrasquad game, with eight strikeouts. He overpowered the minor-leaguers and finished with 58 pitches. After his five innings, he threw a brief bullpen session to reach 80 pitches, his highest total this spring.

“I guess it served its purpose, more or less,” said Lester. “I was able to get my pitch count up, got the innings and got my work. I would have liked to have been on the plane with the team, but it’s all right. Now that I’ve got my pitch count up, I don’t have to worry about anything. There are no limitations going into the season and I’m ready to go.”

As he leaves for Japan, he feels he’s where he needs to be.

“As far as I know,” he said. “It’s been a while since I’ve had a normal spring training. … I feel good, healthy and strong. Everything went without a hitch this spring.”

The left-hander, who will start the second regular-season game against the A’s in Japan, will leave here today at 7 a.m. He’ll have a short layover in Dallas before leaving for Tokyo at 10:15 a.m. He’s scheduled to land in Japan at 1:30 tomorrow afternoon.

Unlike his teammates who traveled on a jumbo 747 charter flight, Lester will fly commercial and he hopes he’s been booked for a first-class seat.

“If not, you will not see one happy person in Tokyo,” he said half-jokingly.

Team doctors told the Red Sox players to stay awake on the trip to Japan to make the transition easier because the team landed at midnight.

Since Lester will arrive in the afternoon, he has been told to sleep as much as possible. His plan is to take a few Ambien to help him sleep, hoping it takes up most of the flight time.

“That’s the plan right now,” he said. “I’ve got some movies I’m taking with me and hopefully it’ll all work out. I get to travel by myself and talk to myself the whole flight. It should be fun.”

Prospect’s diamond sharp

During Lester’s final spring tune-up yesterday, another left-hander showed some impressive stuff.

The Red Sox’ first-round selection in last June’s draft, Nicholas Hagadone, was outstanding in the intrasquad game. The powerful southpaw reached 95 mph on the radar gun and showed a nasty slider, complemented by a devastating changeup.

“He looked good,” said Lester. “That’s the first time I’ve seen him. He’s young and still learning. He threw a lot of strikes, and whatever his out pitch was, it was effective and he got a lot of guys out on bad swings. He throws the ball hard and he’s left-handed, which always helps. He looked smooth, like he wasn’t trying to throw 100.”

If yesterday was any indication, Hagadone has a bright future.
