BOSTON -- Jason Varitek caught more games than anyone in Red Sox history -- and by a wide margin. With Varitek serving as the team leader and captain, the Red Sox won two World Series titles in 2004 and ‘07.

Since his retirement, he has been a tireless member of the coaching staff and front office, working with the catchers on techniques and helping with his evaluations of all baseball matters.

But on Thursday, Varitek performed yet another role for the Red Sox when he served as home-plate umpire.

No that is not a typo. Varitek was in full gear when the Sox took the field for their first Intrasquad game of Summer Camp.

And he looked the part.

“Varitek looked like a regular umpire,” said Red Sox manager Ron Roenicke. “I forgot, actually. I had to do a double-take and saw it was him.”

Varitek inserted himself into the game quickly when he called Jackie Bradley Jr. out on strikes on a nasty pitch by Nathan Eovaldi.

“I got to see him coming out of the dugout right away so I felt like he looked good in the uniform,” said Eovaldi. “I thought he did good, I liked it. I liked having him behind the plate, I felt like he was making some really good calls for me.”

J.D. Martinez did give Varitek a sideways glance after he was rung up. But that is just part of the umpire initiation.

Varitek, wearing a light blue umpire shirt, was demonstrative -- but not in an over-the-top way -- with his strike calls.

Essentially, Varitek represented himself with the same professionalism in this moonlighting performance as an umpire as he did all those years he played in Boston.

How did the idea come about for Varitek to umpire?

“He volunteered for it,” said Roenicke. “We were talking about how to do this right. He said he thought it was important to get as close as possible to a real game. He was not going to be able to be here tomorrow, but we’ll probably have someone standing out behind the pitcher and calling pitches tomorrow.”

It will be good for everyone once Varitek returns to duty behind the plate.

“I think the more times a pitcher can see a more realistic view, the better it is for them,” Roenicke said.

The Boston squad that Eovaldi pitched for won by a score of 4-0 in 5 1/2 innings.

Some players, including Rafael Devers and Martinez, hit for both teams. At times, there was only one or two outfielders.

The Red Sox will do these on a near daily basis until playing some exhibition games towards the end of camp.

While Fenway was eerily quiet aside from the music playing between innings, Roenicke indicated there will be some new bells and whistles the team will experiment with as early as Friday’s scrimmage.

“We're also going to experiment some things with noise,” said Roenicke. “I don't know exactly what it all is, but they want to try some things I think maybe similar to what Taiwan is doing and what Korea is doing. So hopefully it won't be quite as quiet. It was quiet today.

“It was different, certainly. But I guess it's kind of like Spring Training when you play those Intrasquad games before you play those 1 o'clock games and it was similar to that. But different. Everything is a little different. I didn't want to sit where I usually sit in the dugout, because there were too many people there so I kind of moved to the side in a seat. I think we are just constantly adjusting to things and trying to figure it out.”
