NEW YORK — CalTube is baseball's latest Internet innovation.

Cal Ripken Jr. and MLB.com will announce Friday they are teaming to launch GetGreat.com, an instructional Web site that will charge $29.95 for a subscription and $9.95 for an individual lesson.

"I kind of see a coach having a practice, going to go over rundowns that day, and they decide to download the section onto an iPod," Ripken said. "They can actually have a preview of what they're going to talk about first — it might be a 3-minute segment or it might be a 4-minute segment, and it's in a form that they can look at and understand. And you can actually carry that out onto the field and then actually go out and try to practice the fundamentals."

The site will open with about 200 lessons for players ages 8 to 18, parents and coaches. Included will be evaluations of big league highlights by the career ironman, brother Bill Ripken and other major leaguers.

Given Ripken's initial disdain for technology as a player, his involvement in a Web site is a bit of a surprise.

"I wasn't a big video analysis guy because I think I learned and hit through feel," he said.

Ripken views the site is a work-in-progress.

"We're constantly going to be updating this. The only way this is really successful is if it changes and it evolves considerably each and every day," he said.

In a way, he views the Web site as a computerized version of his father, Cal Sr.

"He was always someone that loved his index cards and loved his charts," Cal Jr. said. "And now you can put your index cards and charts in a much more animated sense, where you can relate to kids."

He initially had a dim view of computers but his view changed as he raised his son. Ryan, now 15, learned the rules of the NHL by playing video games.

"We live in an information age, and you want information right at your hand," Cal said. "If you have a question you don't understand, you go right to a computer and you type in the question."
