A New MLB?

Major League Baseball has gotten a lot a critisism for being..."boring". It is without a doubt less popular than the NFL, and there seems to be people going away from the game more than going to it. I have a few ways MLB could spice up their games. Some of these coulden't really happen because they would completly change the game, but, here are some ideas for a "new" MLB.

• 4 Outs per Inning, 7 Innings could add a lot more action. That's 28 outs compared to 27 in the normal game, which is not much of a difference. But adding an extra out would definitely increase scoring.
• Larger Field would make more of those hard foul balls fair, and could also make for some awesome catches. Not deeper, just wider.
• On field performances at the "4th inning stretch" when the game moves to 7 innings and 4 outs. A performance by a band, singer, acrobats, comedian, or anything besides the local girls dance academy (I already saw them at a Bucks game) would be great and fun.
• No more NL and AL would let more teams play each other, and less frequently. Every team plays every team at least once. There are still divisions that play more often, and the division winners play in the playoffs until there are 2 left. That's the World Series. The four best second place teams become wild cards, and the two best have a first-round bye.

• NHL Style All-Star Game is really fun. Two captains (voted by fans) pick a team and the teams are managed by the leading managers. Each team will have a skills contest Friday, a concert by a famous band followed by the HR Derby on Saturday, and the real game on Sunday. Teams will get points for how well they do on each, and the team that wins the game will get a large bonus. Home field advantage in the World Series will be given to the team with a better record.

Most of these ideas are totally unrealistic, but what if...?
