The Best Bargains of 2015: Starting Pitching Version
Yesterday, I went into the best bargain position players for 2015, using projected WAR and salary figures to find out who is likely to give teams the least cost per win. Today, we’re going to go over starting pitching, and see where the bargains can be found in the groups of pitchers both pre-and-post arbitration. Thanks to our awesome, ever-active commenters chipping in on the piece from yesterday (you guys are awesome), we’re also going to hone the calculation a bit to look at the surplus WAR value and get some of the low-priced bias out of the sample.
First of all, it should be noted that this is just going to pertain to starting pitching. Relief pitching is something to tackle for another day, as I believe it should be grouped separately from the starters in a study like this. As I did yesterday, I’ve taken contract data for the 2015 season, merged it with ZiPS WAR projections, and then calculated each player’s cost, in dollar value, per win.
Again, the sample is separated into two groups, those who have reached above-league minimum deals (generally through free agency or arbitration) and those who haven’t. For those who haven’t, I’ve simply set their contract as the league minimum, $507,500. This can vary slightly — each team deals with pre-arbitration pay raises differently, and always in a clandestine manner – but it’s a small enough change to barely influence the data. There is one exception for pre-arbitration players: if a player has negotiated a contract with their team above the league minimum (so they actually show up on the contract reports we have), they will show up in the first group. This didn’t come up often, but it’s best we’re all on the same page.
Let’s begin. First we’re going to look at the first group of starting pitchers — these are mostly the players who have reached free agency or arbitration. I’ll present these findings in both graph and table form: here’s the graph comparing salary vs. projected 2015 WAR for our top 30 starting pitchers:
