In Tuesday's 2-1 win over the Athletics, Youkilis played his 193rd consecutive game at first base without committing an error, tying Steve Garvey for the Major League record.
Youkilis started his streak on July 5, 2006. Garvey played errorless defense at first from June 26, 1983 until June 14, 1985.
"That's a great thing, and hopefully I can carry it on for a long time," Youkilis said.
Interestingly, Youkilis met Garvey for the first time this weekend when the Red Sox played an exhibition series in Los Angeles against the Dodgers.
"It's definitely a great honor," said Youkilis. "Steve Garvey, that's unbelievable. I got to see him in L.A. and got to meet him for the first time. That was really cool and interesting."
Making the feat even more impressive is that Youkilis came through the Minor League ranks as a third baseman, but mastered the other side of the diamond once the Red Sox gave him the opportunity to play there.
"Good for him," said Red Sox manager Terry Francona. "I think what means more is not just going that amount of games, but it's the way he plays, because Youk plays an aggressive first base. The kid comes up as a third baseman and moves to first. This is not a fluke thing he's done. He scoops balls in the dirt, he's active, he's all over the place. I think what this does is brings some attention to him nationally where we can brag about him a little bit."
"It's a pretty good milestone," added Sox third baseman Mike Lowell. "I think at any position when you don't make errors -- and to set or tie a record, you have to be pretty happy about that."
To Youkilis, helping the Red Sox win games is what is most meaningful. He did that on Tuesday not just with his glove, but also with three hits and a terrific slide into home plate in which he was safe by a hair for the tying run.
"I go out there with the mindset every day of trying to play the game the right way," Youkilis said. "Try to do everything soundly, try to go out and have good at-bats, play the field right and run the bases. That's my attitude every day. I try to get better on a daily basis. I can't worry about the streaks."
