Let's admit it: the Angels starting rotation is still something of concern. Actually, that's not admitting anything. That's pretty much common knowledge. And its fueling the pervasive assumption that the Angels off-season (post-Hamilton) has not ended and that Jerry Dipoto and company will make another move before opening day to acquire another starter.
In a search for determining how much a win is worth in the free agent market I decided to delve into Baseball Prospectus' current PECOTA** projections and couple it with the amount of money the Angels will be paying their current starting rotation. There's nothing too heady here, just simple addition and inclusion of some projections.
So far, the Angels have added Tommy Hanson and Joe Blanton to their starting rotation and lost Ervin Santana and Dan Haren. Here's these four players projected WARP from BP along with their 2013 salary.
Dan Haren: 3.5 ($13 million)
Ervin Santana: 1.3 ($13 million)
Tommy Hanson: 3.6 (estimated. 1 million -- arbitration eligible)
Joe Blanton: 0.5 ($7.5 million)
At first glance that seems like a bit of a steal. Even if you include the $4.5 million the Angels paid to get rid of Haren and Santana, the Angels are paying $21 million less for players that will give them an estimated 0.7 less wins. Or they went from paying $5.41 million for a win to %2.07 million. So the Angels replaced two pitchers with slightly less comparable pitchers but saved $21 million dollars. Not bad some may say.
Oh wait. We forgot to include Zack Greinke. Drats!
Here's what the Angels rotation would have cost along with their estimated WARP if they had kept the rotation as is versus what it is now.
Jered Weaver: 3.5 ($16 million)
Zack Greinke: 3.5 (19 million)
CJ Wilson: 3.4 ($11 million)
Dan Haren: 3.5 (13 million)
Ervin Santana: 1.3 (13 million)
Jered Weaver: 3.5 ($16 million)
CJ Wilson: 3.4 ($11 million)
Tommy Hanson: 3.6 (Arbitration eligible - $1 million)
Joe Blanton: 0.5 ($7.5 million - 2013)
Garrett Richards: - 0.2 (400 K)
The current rotation is $36 million cheaper but is estimated to be just over 5 less wins. And despite saving money on the rotation, $23.5 million of it is going to recent bullpen acquisitions and Josh Hamilton in 2013. Leaving the skepticism that the Angels rotation is worse very much warranted. It's a cheaper rotation, though! But does that really matter if overall payroll still goes up?
I like the Madson and Burnett signings and I think Hanson for Walden was a good trade. However, it also feels as if the question marks have just been moved. While last year the Angels bullpen was of concern, now it's the rotation. In the course of a game, neither is mutually exclusive. Still, I am not sure you can bank on shoring up the deficiencies of a starting rotation with a strong bullpen or vice-versa. And even if we go strictly by WARP, the additions to their bullpen are estimated to not make up for the five win difference.
Tomorrow, I'll look a bit more into the money vs. WARP with the bullpen moves and the Hamilton signing.
**The PECOTA projections on Bpro are from the beginning of 2012. They haven't released the 2013 projections yet. So these will adjust.
