The biggest story to come out of the Dodgers camp yesterday was the acquisition of Chase Utley from the Phillies for two minor-league prospects, Darnell Sweeney and John Richy. While Utley will no doubt provide support to a middle infield that is thinner with the injury to Howie Kendrick, there was another event going on in Oakland yesterday — a major-league baseball game, in fact — and one important part of the Dodgers pitching staff once again reminded us that it too might be in need of some help.
I refer to the current state of the Los Angeles bullpen, which has, by a multitude of measures, accounted for among the worst performances in baseball during the 2015 season. On Wednesday, the Dodgers were “swept” in a two-game series by the 53-69 Oakland A’s; this was made especially painful to players and fans alike, I can imagine, considering Clayton Kershaw started the opening game of the series.
Kershaw was able to go only seven innings during that game, exiting with the score tied, and he handed the ball over to a multitude of relievers who displayed various levels of ineffectiveness. That game resulted in a 10-inning Oakland walk-off win — with the bullpen blowing a three-run lead — while the second and final game of the series saw them unable to keep the A’s close in the final frames of another tight contest. The two-game series was probably an encapsulation of a lot of what Dodgers fans have become painfully accustomed to.
Today, we’ll highlight some numbers related to the Dodgers pen, and see what options the Dodgers might have in bolstering the current weakest part of their team.
We have two statistics here, created in 2010, called Shutdowns and Meltdowns. They’re a way of measuring a given amount of win probability added or subtracted (.06 or 6% WPA, to be exact) during a relief pitcher’s performance, and they help outline the struggles we’re talking about. First, let’s take a look at the 10 bullpens in baseball that have the most Meltdowns, i.e. occasions on which a relief pitcher lowered his team’s chances of winning by at least 6%:
