Who Has Been Clutch?
The are seemingly infinite ways to measure "clutchness" -- performance w/RISP, late and close situations, September, RISP and 2 outs, etc. Beyond the Boxscore suggested one other method, which I will use to look at the Mets' performance in the clutch. The method entails comparing Batting Runs (BR,...
Billy Wagner's Most Valuable Pitches
To commemorate Billy Wagner's return this week, I compiled a list of his top 10 most valuable pitches as a Met per WPA. It should bring back some pleasant, and not so pleasant, memories during this lost season. A major caveat of relief pitcher WPA is that relievers often create their own...
Manny Corpas: Why he’s great, why he’s awful, and why the stats show that either way, you’re right.
Manuel Corpas has been one of the strongest members of our pen this season. He's been absolutely excellent, as he still approaches the plate with a solid control over the strike zone, a low walk rate, and a career-low homerun rate. Corpas has been one of the weakest members of the pen, however....

Ramon Castro's Greatest Hits
Plenty has already been said about the Ramon Castro situation, so I won't pile on. Despite his injury issues, Castro was a valuable backup for the Mets and he deserves some kind of tribute. Here it is, Castro's top 10 most valuable Mets plate appearances according to WPA (via Fangraphs). Format...
Best Mets Opening Day Starts
In honor of Opening Day's rapid approach, I took a stroll through the historical boxscores and WPA graphs at FanGraphs and checked out the past 25 years of Mets Opening Days. Why just 25 years? FanGraphs' boxscore data relies on play-by-play files from Retrosheet, which is only complete since 1974...
Post-Previewing The AL MVP
Like I did with the NL MVP Award, I want to take a look at a few different player rating systems and a couple different voting groups. First up, here's a look at a system that includes clutch performance via Win Probability Added. Position adjustments and fielding numbers are taken from Justin's...
