(NEW YORK) -- MLB Commissioner Bud Selig believes the new replay system is working and isn't worried about future calls down the road being an issue.
Selig spoke on Tuesday at the MLB Diversity Business Summit and backed the new system that launched on March 30.
"We've had really very little controversy overall," Selig said. "Everything in life will have a little glitch here and there where you do something new. And are our guys on top of it? You bet. But I'm saying to you again, you'll hear about the one or two controversies, but look at all the calls that have been overturned."
MLBAM chief executive officer Bob Bowman said despite some errors by the umpires, mistakes happen.
"Technology takes a while to work," Bowman said. "I don't know if you ever bought a new car. You don't know how all that stuff works right away. And if you ever get a new phone, it takes you awhile to learn it. We're under 30 days old, and I know we've arrived because ESPN is already criticizing us. And it must be great to be perfect the way ESPN is."
Calls by umpires on the field have been confirmed in 33 of 89 challenges through Monday and overturned in 30, reports USA Today Sports. Twenty five other calls have stood due to lack of "clear and convincing" evidence.
