"I think that's a very good comparison," said catcher Jonathan Lucroy, who caught Thornburg in Spring Training and then faced Lincecum in early May. "Is he going to do what Lincecum does? Not a lot of people do. But in terms of stuff and delivery and windup, very comparable."
Lucroy is on the disabled list with a broken hand, so he was forced to watch Thornburg's Major League debut on Tuesday from the clubhouse. The Brewers promoted Thornburg from Double-A Huntsville to start against the Blue Jays.
"I think this is going to be a good experience for him, getting thrown into the fire," said Lucroy, who jumped to the Majors three years ago. "It was for me. I learned a lot."
Manager Ron Roenicke cautioned against expecting too much, too soon, from a 23-year-old who has made all of 13 starts above the Class A level.
But he buys the Lincecum comparison.
"I see it," Roenicke said. "[Thornburg] has got a little funkiness to him, he's got an electric fastball, he's got a very good curveball, and when all those things are working, [the comparison is apt]. I'm not saying he's [Lincecum]. But he's similar in some of the things he does."
