Renaming Tags

I renamed my /tag/ slug to /news/. I now want

http://www.wrestlescoop.com/tag/chris-jericho/

to redirect to: http://www.wrestlescoop.com/news/chris-jericho/

Is there a simple way of redirecting this without a plugin that requires adding every single tag that I’ve created?

After I changed the slug,
http://www.wrestlescoop.com/tag/chris-jericho/ redirects to a random Chris Jericho news article.

Thanks for your help.
