Many of the top players on the free-agent market have already signed this winter. There are some solid players such as Michael Bourn that are still on the market, but many teams have their lineups set for the 2013 season.
Having a strong lineup is a large part of the equation for a team that is looking to reach the postseason. A good starting rotation is equally important, if not more important for success.
After all of the changes that were made this winter, some teams find themselves with improved starting lineups that should put up large run totals throughout the year.
