Spitballing: Blanton in the Phillies’ Rotation February 25, 2011

The Phillies have one of the best rotations, on paper, in baseball today. Although some people are measured in their optimism, including Jayson Stark, I think the important thing to remember is that we’re arguing over whether they’re “the best ever,” not if they’re going to be competitive. Rotations that bring this kind of excitement at the beginning of the year are few and far between. The Mets, for example, aren’t drawing this kind of expectation – guys like R.A. Dickey and Mike Pelfrey are solid, but they don’t have the deserved reputations of Roy Halladay, Roy Oswalt, Cliff Lee, Cole Hamels, and Joe Blanton.

I’m hardly the first to say it, but Joe Blanton seems to be the odd man out. He’ll be making about $8.5 million next year. Blanton faced 765 batters last year, fourth behind Halladay, Hamels, and Kyle Kendrick. Immediately behind Blanton was Jamie Moyer with 460 batters faced. For the record, the fifth-most-active pitcher faced 362 batters in 2009 (Chan Ho Park) and 478 in 2008 (Adam Eaton). Let’s take that number and adjust it to about 550 batters faced, since Blanton will get more starts than most fifth starters and he’ll stay in longer since he’s a proven quantity. In a normal year, the Phils face about 6200 batters, so that means Blanton’s 550 will be about 9% of the team’s total. (That figure is robust even in last year’s Year of the Pitcher with depressed numbers of batters faced.)

According to J.C. Bradbury’s Hot Stove Economics, this yields an average marginal revenue product of 3.15 million. This figure is based on the average rate that pitchers prevent runs and the average revenue of an MLB team. Obviously, Blanton is a better than the average pitcher (ignoring his negative Wins Above Replacement last year) and the Phillies make more money than most teams, but this is a pretty damning figure.

The other thing to take into account is that Blanton’s marginal wins aren’t worth as much to the Phillies now that they have a four-ace rotation. He won’t get every start and he won’t be a 20-game winner. Even if he were, he’ll be providing insurance wins – he might have an extra ten wins over a AAA-level replacement, but chances are that those wins won’t make the difference between making the playoffs and missing them when you figure in the Phillies’ solid bullpen and run production.

Instead, let’s say Blanton goes to the White Sox, just to pick a team. Jake Peavy and Edwin Jackson combined for 765 batters faced, so plug Blanton in for Freddy Garcia with 671 batters faced – a worst-case scenario. That would be 10.85 % of the batters faced, bringing him up to about 3.8 million. In this case, though, you have a team who finished 6 games back and missed the playoffs. If you replace Garcia with Blanton, you stand a very good chance to make the playoffs. That’s another way of saying that the Phillies’ 6-game lead over Atlanta (the NL wild card team) was worth less than the Twins’ 6-game lead over the White Sox (when neither team had as many wins as the AL wild card).

Economists would refer to this as a diminishing marginal returns situation – when you have fewer wins, around the middle of the pack, each additional win is worth a little less. This captures the idea that taking a 110-win team and giving them 111 wins would cost a lot of money and not yield much extra benefit, but a 90-win team making 91 wins might let them overtake another team.

The upshot of all of this? Trade Blanton for prospects. Rely on the bullpen and develop a future starter. Roy Halladay won’t be competitive forever.

The Best Game Ever July 30, 2010

Two of my favorite things about baseball happened during tonight’s game between the Yankees and the Indians.

First of all, in the top of the ninth inning, corner infielder Andy Marte pitched for the Indians. Marte pitched a perfect ninth and coincidentally struck out Nick Swisher, who was brought in to pitch for the Yankees in a similar situation last year and struck out Gabe Kapler of the Tampa Bay Rays. I can’t promise it’s true, but I think that puts Swisher at the top of the list for involvement in position player pitcher strikeouts.

Marte’s presence was necessary because the Indians used seven other pitchers. Starter Mitch Talbot went only two innings, and the Indians got another two out of Rafael Perez. Frank Hermann took the loss for the Indians during his 1 1/3 innings. Tony Sipp pitched another 1 1/3, and Joe Smith managed to give up four earned runs in 1/3 of an inning before being removed for Jess Todd for an inning. In the bottom of the 9th, Marte was all the Indians had left.

Not to be outdone, Joe Girardi gave up his designated hitter by moving his DH – funnily enough, it was Swisher – into right field as part of a triple switch. Swisher moved to right field; Colin Curtis moved from right field to left field; Marcus Thames moved from left field to third base;  finally, pitcher Chan Ho Park was put into the batting order in place of Alex Rodriguez, who came out of the game.

Finally, A-Rod is up to 33 plate appearances without a home run. Assuming his standard rate of .064 home runs per plate appearance, the likelihood of this happening by chance is .936^{33} = .113 \approx 11.3 \% . I stand by my belief that there’s something other than chance (i.e. distraction or other mental factors) causing Rodriguez’s hitting to suffer.
