As we edge closer to the start of the 2011 Major League Baseball season, it’s getting easier to live-stream games, no matter your level of technical prowess.

A week after Apple announced full MLB.TV integration with its Apple TV media-streaming gizmo, Facebook has now fallen for the national pastime, unveiling an experimental live-stream service that’ll broadcast select spring training games for the next two weeks, until Opening Day. There are no concrete plans to continue the service into the regular season, although MLB execs are not ruling it out.

Even before this recent spate of announcements, MLB boasted a fairly impressive slate of platforms from which you could live-stream games: Mac, PC, iOS devices, Android phones, PlayStation 3, Roku and certain LG televisions.

Then Apple stepped up with its comprehensive iOS 4.3 update, which enables any Apple TV to utilize existing MLB.TV subscriptions — costing either $100 or $120 for a full season — to stream games straight to your high-def TV.

MLB’s foray into Facebook is an obvious plow to draw more people to its MLB.TV service, but pending its success over the next fortnight, it may yet portend some larger forthcoming entry into a market that’s ripe for growth.

Subscribers to MLB’s At Bat app already receive one select game a day to live-stream, whether they are MLB.TV subscribers or not. That app only costs you $15 for an entire season of mobile updates and streaming radio broadcasts.

A long-term partnership with Facebook, which recently announced plans to stream Hollywood movies over the platform, would make sense for a sport continually struggling to reach the NFL and NBA and in terms of national exposure and popularity.

Provided this proof-of-concept move proves fruitful for MLB (and for Facebook), you can bet we’ll see some sort of fully loaded, integrated MLB streaming service at Facebook.com/mlb sometime before Opening Day 2012, if not sooner.
