This is a very interesting MLB season. The National League East Division has four teams within 1 1/2 games of each other with the highly paid, but poorly performing Dodgers buried in last place. This one may go down to the last week of the season. The American League East Division has four teams winning more than half their games. Separation will have to occur when they play each other more.
The race I am focused on is in the AL Central where my beloved Twins play.
In this division, the Kansas City Royals are emerging as a real contender. It has moved ahead of Cleveland for second place and is within the critical five game margin that means one good week for it and a bad week for Detroit and they will be neck and neck.  All teams have bad streaks and good streaks, the Royals had its bad streak and the Tigers will have one. 
The Royals success pleases me because I saw this team at the end of the 2011 season and predicted great things for 2012. It was not to be. Players such as Hosmer, Butler, Gordon, and Perez lead this team that is for real now, and James Shields will win going forward if the team scores more than 2 runs a game for him.
Gene Mauch, the great manager said, “teams have to learn to play, then to win, then to win when they have to.”  Kansas City has learned to play, and is learning to win. We will learn if it can win when it has to sometime after Labor Day. Detroit will be hard to beat with its superb starting pitching, but its relief pitching is suspect. This will be a great race and that is all I ask for in a Major League Season and this one has great races that will keep us engaged until the snow flies.
