Google's little $35 dongle is like a fine wine: it just keeps getting better with age. Today, the Chromecast is adding support for MLB.tv, letting you push out live out-of-market games right to your TV from a smartphone or tablet. The only caveat is that you'll need an MLB.tv Premium subscription to do so, but chances are most of you hardcore fans of America's pasttime already have one of those. If you do, the only thing left to do is grab the MLB At Bat app from Google Play or the App Store -- an update which brings Chromecast support to these apps should be rolling out as we speak. And while you're at it, perhaps you may want to download R.B.I Baseball 14, so you can have an all-baseball day to yourself.
