Kansas City Chiefs running back Larry Johnson ignited a firestorm in the local and national media late Sunday when he publicly criticized head coach Todd Haley on Twitter following the Chiefs’ 37-7 loss to the San Diego Chargers.

Johnson, who tweets under the name @ToonIcon, criticized Haley in a series of tweets first reported by Chiefs bloggers late Sunday and later by Yahoo Sports columnist Charles Robinson early Monday.

According to the Yahoo Sports report Robinson filed early Monday, Johnson wrote:

“My father played for the coach from “rememeber the titans”. Our coach played golf. My father played for redskins briefley. Our coach. Nuthn”

Later Johnson engaged angry Chiefs fans and even used a homophobic slur while responding to one fan. Johnson’s final tweet of the night taunted fans and reminded them that “u don’t stop my checks” according to media reports. At some point following Sunday’s exchange, Johnson made his Twitter account private.

Update 10/28 - ESPN is reporting that the Chiefs have suspended Johnson from the team for two weeks.

Update 11/9 – The Kansas City Chiefs have released Johnson in part due to his comments on Twitter.

This week many Major League Baseball teams joined Twitter so I am publishing a list of official team accounts. This information may also be found on the “Teams & Leagues” page on the Complete List tab above.

The Players
There are already several star MLB players on Twitter, all of whom seem to have started using the service during this past off-season. New York Yankees ace and star free agent acquisition CC Sabathia is among the MLB players already using Twitter. The recently retired Red Sox pitcher Curt Schilling is also on Twitter and uses the site to communicate with fans and promote his new game development venture, 38 Studios. Other MLB players on Twitter include Phillies reliever Chad Durbin, Yankees outfielder Nick Swisher, Giants closer Brian Wilson, Rangers reliever C.J. Wilson and Giants starter Barry Zito.

Each player uses Twitter differently. Sabathia and Swisher don’t tweet much but Wilson is very open and answers fan questions regularly. Still, it’s great to see MLB players embrace Twitter to communicate with the fans and it’s likely that even more players will join Twitter this season.

MLB on Twitter
The players aren’t alone in embracing Twitter. MLB has taken an active role on Twitter, too. MLB’s Mark Newman runs the MLBlogs Twitter account and keeps everyone updated on the newest blogs on MLB.com (sign up for your own blog here) and on the latest MLB players to join Twitter.

If you enjoy watching MLB games on your computer through MLB.tv, you’ll be happy to know that you can follow the MLB.tv Twitter account for the latest news on the service and baseball in general.

MLB Teams on Twitter
If you’re an Athletics, Diamondbacks or Royals fan, you can follow Twitter accounts for an insider’s look on your favorite club. Catherine Herman, a Dbacks PR staffer, offers an inside look at the ballclub via her DbacksPRGirl account. Around the Horn KC offers updates from the official Royals blog on MLB.com. Finally, the Athletics maintain an official Twitter account to inform fans about the latest team news and promotions.

While there are only a handful of official club accounts on Twitter right now, I’ve heard that many teams will launch official accounts at some point this season. Follow us on Twitter for the latest updates.

Team Beat Writers on Twitter
If you enjoy reading about your favorite team on MLB.com or in the local media, you’ll be happy to learn that several MLB beat writers are already covering their teams on Twitter in addition to their normal media outlets. Here is a list of team beat writers on Twitter, divided by ML division. Please note this is not an exhaustive list; I am always looking for more writers.

AL East
Blue Jays – Jordan Bastian, MLB.com
Rays – Marc Lancaster, Tampa Tribune
Yankees – Bryan Hoch, MLB.com, Pete Abraham, The Journal News

AL Central
Tigers – Jason Beck, MLB.com
White Sox – Joe Cowley, Chicago Sun-Times

NL Central
Astros – Alyson Footer, MLB.com

Finally, several national baseball writers maintain Twitter accounts, including ESPN’s Jayson Stark and Keith Law and Baseball Prospectus writer and injury expert Will Carroll. Please note that while Peter Gammons has an account, it is new and now private so I am not listing it here.

If you prefer to read blogs, I recommend Tim Dierkes’ excellent MLB Trade Rumors site and Twitter account. For a full listing of MLB blogs (and other sports blogs, too), check refer to the Blogs page on the full list.

I hope that this MLB roundup helps you enjoy the 2009 season a little more in some small way. I fully expect more MLB players, teams and writers to embrace Twitter this season so it looks like a good season for baseball fans on Twitter!
