UZR at Fangraphs includes outfield arms and double plays


Baltimoron

Recommended Posts

- UZR now includes outfield ARM runs and Double Play runs.

- ARM and DPR (Double Play runs) are broken out separately in the fielding sections.

- All player Win Values have been updated to include these additions.

- There have also been some slight changes to UZR that adjust for how fielder’s choice plays were being calculated.

Nick was second in runs saved though outfield throws in 2008 amongst qualifiers (link) at +6.8. (Click "ARM" to sort by that column, its expressed in runs). Note AJ at +3.2 was a top 10 outfielder amongst qualifiers in terms of runs saved with his arm.

With the arm scored added AJ at +10.3 in CF ranks as the 4th best CF in baseball according to UZR in 2008.

Also, the unappreciated and overly-hated Jay Payton's superstellar 2008 defense only shines more, as he was +3.8 with his arm for a total 2008 OF defensive rating of +13.6. He still sucked, just not as bad as you might think only looking at his no hit offensive line.

The 2008 Os were also the 2nd worst in baseball in turning double plays last year. link (click the column "DPR" to sort by double play runs). Although Izturis should help, UZR does not rate BR as ever being good at DPs and thinks he was subpar the last two years. link.

Here are the leaders in ARM over the past three years:

Alfonso Soriano - +25.6 runsJeff Francoeur - +23.4 runsIchiro Suzuki - +12.5 runsNick Markakis - +10.8 runsMichael Cuddyer - +10.4 runs

If you read the comments to the Fangraph's piece, people clamor to open the black box. We will see, apparently the methodology will be exposed. Until then I don't expect much on the underlying calculations, but UZR itself is open and peer reviewed so it is coming from a respected/established source.

It is interesting that Jones' arm ranks well, because he seemed very erratic in his throws. When he overcomes that, he's really going to put up some numbers.

Payton graded very well defensively both years he played for us, but I never thought he was anything better than a little above average at most with his range, and his arm was just awful. It's a case where I can't make sense of his numbers. Maybe he's very good at positioning.

Cool. Definitely needed an Outfield Arm category.

Alfonso Soriano - +25.6 runs

Soriano's arm that good? :002_ssleepy:

Nice stat to have, but I bet still a very subjective one. Not sure, but I don't think the stat takes into account the speed of a baserunner, does it? So throwing out Ichiro at home might score the same as throwing out Kevin Millar at home so the baserunner situation could adversely impact this stat (possibly?..? Could be wrong and this is accounted for).

Anyone that can clarify how this stat is calculated go for it. :D

    • Eh, noise. IDGAF anyway, having cut the cord long ago. I know the feeling though… Dish pulled that BS a couple years ago. I’m hoping Rubenstein can find a way to ala carte everything. There will certainly be demand.
    • I haven’t seen this mentioned anywhere, but Irvin morphed his slider into a cutter last year that is by far his best pitch by Stuff+. He threw it 16% of the time too, decent usage but could be increased more. He’s always going to score poorly in stuff for pitch models but very well in command grades, so even some slight upticks in stuff could make a big difference. His curve is also decent. He relies a lot on his fastball/sinker/change, so I’d be interested in him moving more towards the cutter/curve (which generally are still effective against RH batters). Irvin was absolutely unreal horrific in his first few starts last season, which tanked his season numbers (particularly xERA), but really righted the ship after that. He’s a decent piece to be a 5th starter, he’s been very durable, throws a lot of strikes and as a result can pitch a lot of innings (if you aren’t pulling him early in close games), and is a good fit for OPACY. It’s just a bad spot that our depth chart is already whittled down to him being that to start the year. 
    • Things aren’t looking good for MASN and comcast.     Would still figure they find a way to get a deal done but it doesn’t seem as certain as I think it was.
    • Verlander needs 140 IP and a clean doctor's note to assure himself of 1/35 next season but if he misses that I could see him somewhere on Elias' target list for the year over year Lyles-Gibson-Kimbrel 1-year contract stretch. Its a bit of an art question for baseball how it wants to grapple with all Friedman and Driveline have brought to the game.    Roki Sasaki or Paul Skenes or even Grayson Rodriguez might be their generation's Justin Verlander but today's game will constrain them from revealing it as fully to baseball fans even if they are. Verlander has become a TJ statistic in recent years, but for me he really isn't - every bit of work on his Hall of Fame plaque was done before the surgeon took some of him.
    • Buried in the article, but it says this:   “Verlander said he heard at the trade deadline that the Dodgers and Orioles were interested, and he said he’d have accepted Los Angeles or even Baltimore if those were the options. “I’m from Virginia,” Verlander said. But when Houston, where he’d won his rings, became viable, he said he was happy to “steer things” that way.”
    • Has the added benefit of being on the 40-man already, so nobody necessarily needs to be removed for him to come up as a reliever later in the season.
