Youkilis played for the Boston Red Sox when Hoyer was with the organization from 2002-08. The White Sox acquired Youkilis in a trade on Sunday.
“I like that move a lot,” Hoyer said on "The Carmen, Jurko & Harry Show" on ESPN 1000. “I really like Youkilis. He’s as good a competitor as you’re going to find in this game. If there’s one knock on him, it’s that he’s really emotional and really cares about every at-bat. You can have a lot worse things than caring about every single at-bat.
“I think he can bring a great thing in the clubhouse when they see how serious he takes every at-bat. Whether the team is up 7-1 or down 10-1, he doesn’t care. He takes every at-bat really serious.”
Youkilis has averaged 4.31 pitches per plate appearances in his career and has often been among the major-league leaders. He took 23 pitches in his four at-bats with the White Sox on Monday.
“He grinds at-bats,” Hoyer said. “He works the pitcher. I think a lot of things he does on a baseball field [are] missed because they don’t see how he wears down a pitcher, how many pitches the opposing pitcher just has to use just to get through Youkilis and how tired he is.
“I like that move a lot for the White Sox because he’s going to grind like crazy. I think he’ll bring a lot of competitiveness to a pennant race.”
Youkilis went 1-for-4 in his White Sox’s debut on Monday. He’s hitting .233 with an on-base percentage of .314 and a slugging percentage of .373 this season.
