Best Outfield Arms of 2006
by John WalshFebruary 15, 2007
It was the last day of 2006 and I was getting ready for a little New Year's Eve get-together. While I was blowing up some balloons, I saw a new message in my inbox, and after a click I realized that I had just received a late Christmas gift—the 2006 play-by-play data had just been released by Retrosheet. Oh, joy! I know, it's pretty nerdy to get worked up over a big bunch of numbers, but I usually can't wait for the new release to come out, and this year the crew at Retrosheet.org outdid themselves by bringing home the data two or three months ahead of schedule. Nice work, boys.
So, the first order of business was to determine the best outfield arms of 2006. Last year I developed a method for evaluating outfield arms, which you can read about here and here. The first article has all the gory details of the methodology, here is the short, painless version: using play-by-play data, I consider five different situations when an outfielder's throwing ability comes into play:
- Single with runner on first base (second base unoccupied).
- Double with runner on first base.
- Single with runner on second base.
- Fly out with runner on third base, fewer than two outs.
- Fly out with runner on second base, fewer than two outs (third base unoccupied).
Right Fielders
I always start with right field, I suppose because that's where we expect to find the strongest outfield arms, and I want to get right to the best stuff. In my view, the best right field arm in 2006 belongs to Alexis Rios, the Blue Jays right fielder. Here's a table showing Rios' performance:
Alexis Rios - RF
Situation | Opps | H K | Hexp Kexp
S-1B | 44 | 31 2 | 25.4 0.6
S-2B | 30 | 20 1 | 12.7 1.6
D-1B | 16 | 10 1 | 9.3 0.8
OF-3B | 11 | 5 0 | 2.6 0.4
OF-2B | 22 | 14 1 | 12.5 0.5
Overall | 123 | 80 5 | 62.5 3.8
Notation:
Opps - number of opportunities
H - Hold: runner did not take extra base.
K - Kill: runner (or batter) thrown out on bases.
Hexp - Expected Holds based on league average play.
Kexp - Expected Kills based on league average play.
Each of the first five rows shows
how Rios did in the five situations considered. You can see that in
every category, runners tended to hold more than they did on average.
Overall, Rios "saved" around 18 extra bases by holding runners. For good
measure, he also had one more "kill" than expected given his opportunities. Rios
ranked pretty high last year (5th among right fielders), but really
aired it out this year.
The worst performance in right field—in any field, actually—was turned in by Shawn Green:
Shawn Green - RF
Situatation | Opps | H K | Hexp Kexp
S-1B | 57 | 22 0 | 32.6 0.7
S-2B | 35 | 11 0 | 14.0 2.0
D-1B | 21 | 11 0 | 13.1 0.9
OF-3B | 12 | 1 1 | 2.8 0.5
OF-2B | 15 | 8 0 | 8.5 0.3
Overall | 140 | 53 1 | 71.0 4.3
Ouch! That is bad. Green can't throw anybody out (only one kill, when
four were expected) and the runners know it. They ran hog-wild on the
Diamondbacks/Mets right fielder, taking the extra base fully 18 times more
than they would have against an average right fielder. Green also ranked
dead last among right field arms last year—they need to get
this guy closer to the runners he's trying to throw out. Maybe he can
swap positions with Carlos Delgado.
I have converted these hold and kill numbers into runs saved above average, and ranked all right fielders according to the number of runs saved per 200 opportunities (generally, around one full season's worth). Here's the list of all right fielders who had at least 100 opportunities in 2006:
Inn/9 Opps Kill+ Hold+ Runs Runs/200
Rios_Alexis 106 123 133 129 7.1 11.6
Hawpe_Brad 134 187 202 110 9.6 10.2

Jenkins_Geoff 122 138 46 96 -3.7 -5.4
Green_Shawn 125 140 23 73 -9.1 -13.0
Notation:
Inn/9 - Defensive games
Opps - Opportunities
Kill+ - Normalized kill rate, e.g. 110 means 10% more kills than average
Hold+ - Normalized hold rate
Runs - Runs saved above average
Runs/200 - Runs saved per 200 opps
You can see that Brad Hawpe was excellent as well—in fact, since he played
more, he actually saved his team more runs than Rios. Seeing J.D. Drew so
low surprised me, since he is considered to have a strong arm. It may be that his shoulder problems in 2006 were
hampering his throwing.
Center Fielders
You know what? Willy Taveras has a great throwing arm. Last year I was surprised to see him rank quite highly (sixth out of about 30 center fielders with 75 opps). Here's what I wrote about him then:
Taveras eliminated more than twice as many base runners as expected. He did not hold runners well, but I think it's fairly common for rookies to have poor hold rates, since opposing teams are going to test their arms. Especially, when they are six feet tall and weigh 160 lbs. Six of Taveras' kills came in the critical situations 2-4, where the key play occurs at the plate. This results in Taveras having a large number of runs saved.In 2006, word had definitely got around about Taveras' arm: his hold rate of 108 was well above average. But, he still managed to gun down more than twice as many runners as the average center fielder. Very impressive work, by the now-Rockies center fielder. Here's the complete list of center fielders with 100 opportunities in 2006:
Inn/9 Opps Kill+ Hold+ Runs Runs/200
Taveras_Willy 124 119 211 108 3.5 5.9
Sullivan_Cory 94 122 106 102 1.6 2.6

Gathright_Joey 113 175 77 80 -5.8 -6.6
Damon_Johnny 121 146 49 87 -5.0 -6.9
One thing to note right away: aside from Taveras, nobody really stood
out in center field in 2006. In fact, there isn't really much difference
between number three, Chone Figgins, and number 15, Juan Pierre. The bottom two,
though, Joey Gathright and Johnny Damon are genuinely atrocious throwers, at least
they were in 2006. Damon ranked very poorly last year—well,
nobody is surprised by this. I think most of us when seeing Damon
throw conjure up an image something like this.
Left Fielders
The Rodney Dangerfields of the outfield throwers, left fielders never get no respect. Nevertheless, many left fielders save (or cost) their team significant amounts of runs each season. The cream of the crop in 2006 was the Dodgers' Andre Ethier, who doubled his expected kill total and was also excellent at holding runners.
Inn/9 Opps Kill+ Hold+ Runs Runs/200

Podsednik_Scott 121 130 47 91 -4.9 -7.6
David DeJesus had a curious performance: a low Kill+ with a very high
Hold+. Typically, you see this kind of pattern on established players
who are living more on reputation than present value. DeJesus, of
course, doesn't fit that description, so it'll be interesting to see how
he rates going forward. DeJesus also was great in center field in
2006. He did not meet the 100 opp minimum, but his Runs/200 figure was
off the charts at 15.0.
A Picture is Worth 1000 Words
It's not really, otherwise I could submit a couple of plots each week and my THT
editors would be satisfied. Oh, were life that easy. Anyway, as I
wrote in a previous article, I like to make graphs with colored dots
and stuff so here you see a plot of outfield arms for 2006.
I have have a suspicion that some readers are put off by these scatterplots. I once came across a discussion of one of my articles, an article that happened not to have any plots, on a baseball forum. One poster commented that it was so nice to be able to read a Hardball Times article without any of "those meaningless scatterplots." Well, I'd like to convince you that this plot is not meaningless. Here goes...
Each point on the plot represents an outfielder for the 2006 season. The position along the x-axis (that's horizontal) gives Hold+, while the y-axis (vertical) shows Kill+. Left, right and center fielders are color-coded as noted on the plot. The dotted grey lines show the average for each quantity: players above the horizontal grey line were better than average at killing baserunners and those to the right of the vertical line were better than expected at preventing runners from taking the extra base.
Players appearing in the northeast quadrant are better than average in both measures and have the best outfield arms. And conversely, players in the southwest quadrant have the weakest arms. Geez, look at Shawn Green there, he looks like Easter Island on a map of the South Pacific Ocean.
Better Than Their Stats
Although we are capturing quite a bit of an outfielder's throwing duties with our five situations, we don't get all of it. For example, an outfielder guns down a runner trying to stretch a single into a double. It's an important play and not uncommon, but unfortunately, it's hard to use that kind of play in this analysis. That's because, although we know how many kills of this type an outfielder had, we don't know how many opportunities he was given. In fact, it's not even easy to define a "single stretched into a double" and in any case, such plays (when the runner is safe) just appear as a double in the play-by-play data.
So, while we can't somehow work these plays into the system, we can highlight the outfielders who had a large number of assists that were not captured by our metric. Head and shoulders above everybody else in this regard stands Alfonso Soriano. The first-time left fielder led the majors with 22 outfield assists last season, but only 10 of them came in one of our five situations. Twelve "unaccounted for" assists is an unusually high number. In Soriano's case most of the missing assists occurred when the batter tried to stretch a hit, but Soriano also doubled off the runner after catching a fly ball five times. A perfect ranking system would probably rank Soriano as the top left field thrower in 2006.
Here is a list of outfielders with at least five "lost assists":
Soriano (LF) 12 Beltran (CF) 6 Griffey (CF) 5 Cabrera, Me (LF) 5Along with Soriano, each of the guys probably deserve a boost in their rankings shown above.
Coming Soon
Next time I'll have a look at the most valuable outfield throws of 2006 from the perspective of Win Probability Added. I'll also have a rankings by team and perhaps a couple of other things on outfield arms.
