The first-quarter mark of the 2013 MLB season has come and gone, and as the weather heats up, so too will the divisional races across the league.
For the first time since regular-season play began, the teams at No. 1 and No. 2 in these power rankings retained their positions for consecutive weeks.
Things are still very close at the top, and league wide for that matter, as 13 teams currently have between 20 and 25 wins on the season.
With that, one week's performance can make a big difference, and there was again a good deal of movement throughout the rankings as a result.
Be sure to check back here every Monday morning for an updated look at where your favorite team stands.
