The MLB is unlikely to expand instant replay beyond its current incarnation. "I've talked to a lot baseball people about this recently -- that includes on the field and executives," said Bud Selig. "Believe me, they have a lot of trepidation about expanding it. [Angels manager] Mike Scioscia put it very well: The umpires get it right 99 percent of the time. "Times change, but I'm still in favor of keeping the human element as a part of it, and I'm also very concerned about pace. I think there are other ways we can make corrections. During the offseason we'll review everything. I've made my position clear, and by the way, I think it's the position of most people in baseball. You have to be very careful when you tamper with a sport."
