Not a whole lot changes during the first month of the season. There simply haven’t been enough plate appearances yet to knock established players for poor performances, ditto boosting them due to strong performances. Injury is the biggest reason why players move from tier to tier at this point of the season. Our preseason consensus rankings can be found right here while the April tiers are right here.
How much longer do we consider Pujols an elite player? He’s off to another slow start (89 wRC+) and it’s painful just watching him run these days because of his knees and plantar fasciitis and whatever else. The homers and RBI totals are still there, but everything else is going south. Pretty scary.
