Four arms good, five arms bad
Baseball Primer is still down, and I want to talk about this, so:
The Colorado Rockies announced today that they will be going with a four man rotation until the end of the season.
Over the last couple years several teams, most notably the Blue Jays and the Reds, have considered it, but if the Rockies follow through, it would be the first time since 1995 that any team has only used four starters for any significant length of time.
Rany Jazayerli of Baseball Prospectus wrote an excellent series of articles on why teams – if they do it right – might gain quite an advantage by going to a four man rotation, and it looks like the Rockies know what they’re doing.
On the other hand, the four pitchers the Rockies will be using aren’t that great (though their 5th starters had an ERA of 17.47 in 3 starts). And the Rockies aren’t exactly known for following through on ideas. But I hope it works, if only to reward them for being willing to try something new.
