Roku users now have something else to smile about. In addition to Netflix and Amazon on Demand, Roku users can now access baseball games from premium MLB.tv accounts. This means live, out-of-market games as well as on-demand games from the past week.

The downside is that you have to be a subscriber of the paid MLB.tv service, which costs $35 for the remainder of the 2009 season. But chances are that if you are a subscriber already, then you are a serious baseball fan, so it’s probably worth it. The Roku box would be a great way to get on-demand and live baseball on your TV.

Back in the stone age, if you wanted to know how fast you could pitch, you needed a radar gun, which was huge and expensive. Only Major League dudes had them and they pointed them at every pitcher in the league, all for the sake of stats. Well this is the 21st century bub. You don’t need a radar gun anymore. We’ve shoved the whole thing into the ball itself.

The SmartBall shows you exactly how fast you throw it. I hear ya. The ball is no longer regulation with the added weight. And yeah, if you hit it with a bat, it will likely die. But it should be a great way to measure your speed and then improve your speed.

It’s beginning to look a lot like a redneck Christmas…I mean how much do you have to drink during a typical day, to say to yourself, “I need that there hat!”. If you see nothing odd about this bottle opener hat, then chances are pretty good that you attend Nascar races while simultaneously courting your sister. In case it’s not obvious, the Guinness Bottle Opener Baseball Cap has a metal hook on the brim to tear off caps, and it’s officially licensed by the beer company and all.

The cap sells for $25, which isn’t too bad if you absolutely must have it. But you’re probably thinking that your teeth have done the job thus far, and they can probably open another couple hundred beers. Cuz that $25 should really go toward brew.

MLB fans will love these MLB-themed gaming PCs from Commodore. Whether they will hit a home run with them is hard to say, but Baseball fans now have their own fancy machines. The officially licensed desktops feature an exclusive C-kin high-definition paint job and a Core i7 inside.

Don’t expect them to be cheap. The paint job process alone is much like the one on your car. Not some vinyl sticker. It’s baked on. The MLB range of Commodore Gaming computers is being launched now with a choice from four teams, New York Yankees, Philadelphia Phillies, Boston Red Sox and New York Mets. Additional teams will be added in the coming weeks.

Baseball fans can now show some love for their favorite team with a MLB Baseball cap USB mouse. You can choose from 17 Major League Baseball logo designs. Specs include: 800 cpi, compatible with windows XP, ME, 2000 and 98, Button swap for left or right handed users and all the other stuff a mouse does to enrich your life. It will cost you $24.95 and hopefully they have your team. Get a mousepad with your favorite MLB players bald spot and it’s perfect.

When you’re playing a game of catch, a radar gun isn’t exactly the most convenient way to measure a ball’s speed. The Glove Radar is an affordable way to measure how much heat your friend is throwing your way. It attaches to the back of your glove with a weather-resistant nylon cord. Sure, it looks dorky, but what are ya gonna do?

It uses microwave Doppler technology to measure the ball’s speed as it approaches. When the ball arrives you’ll see it’s speed indicated in mph on the LCD display. The Radar is powered by a single 3V lithium battery, which isn’t rechargeable, but it’s good for about 5,000 speed measurements. You’ll probably be bored with it long before then.
