Protrade, a company based in San Mateo, Calif., that operates a fictional “sports stock market” for fans, said shares of the Yankees have risen about 7.5 percent after the Clemens signing. That increase suggests that most fans expect a difference of about three or four wins, company vice president Jeff Maname said.
J.C. Bradburyconomist and professor of sport science at Kennesaw State University and author of “The Baseball Economist: The Real Game Exposed,” said four months of Roger Clemens should be worth about $12 million to a team. But he also acknowledged that Clemens may offer the Yankees things that his statistical analysis doesn’t take into account, such as the value of veteran leadership or the unique characteristics of the New York market.
Analysts who have studied the deal also said determining Clemens’ value is tricky because there are so few pitchers to draw comparisons with. Nolan Ryan, a power pitcher like Clemens, went 5-9 with a 3.72 ERA in 27 starts for the Rangers in 1992 at age 45cq-stats. A season later, Ryan went 5-5 in 13 starts with a 4.88 ERA. Phil Niekro and Charlie Hough has success past age 45 but threw the knuckleball.
“On the face of it, this is a lot more than what I’m stating that he should be paid,” Bradbury said. “But there’s probably nobody who has his kind of starpower who is also that good.”
