Which Teams are the Best Bargains?

About this Viz

The Angels own the fourth-best record in baseball — just a half-game behind the second-best Red Sox and Dodgers — but have the fourth-lowest Fan Cost Index. The other four teams in the bottom five in cost all have losing records. Overall the Angels have won 59.7% of their games, and at home they’ve won 61.9% of the time. That makes an Angels ticket an excellent value. On the flip side, the Mets have the fourth-highest cost index in baseball but a putrid 65-85 record (though they have won one more game at home than they’ve lost, so there’s that).
