Just Say No to Rowand
Amidst the Phils' exciting run-up to a possible postseason spot, there's some worrisome noise coming from the trainer's room. Aaron Rowand is saying that he's ready to return to action if the team makes the playoffs.
If they do make it to the post-season, Charlie Manuel should loudly just say no to Rowand returning to his everyday role with the team.
Ignoring Rowand's fabled grit and emotion, let's look at reality instead. Here's what the facts tell us: the Phils are a better team without Rowand in the lineup or on the field.
First, let's look at a simple measure, one that many fans will appreciate the most: the team's record with and without Rowand.
| Record | Win % | |
| With | 56-54 | 0.509 |
| Without | 25-19 | 0.568 |
The Phils have played better without Rowand than with. That's a small sample size, though, and smart fans know that a simple record analysis doesn't get at an individual player's contribution because so many other factors come into play.
So, let's try to isolate Rowand's contribution compared to the contribution of other center fielders in his absence. Here's a chart comparing Rowand's performance at the plate and other center fielders' performance in the games Rowand has missed:
| BA | OBP | SLG | |
| Rowand | 0.262 | 0.321 | 0.425 |
| Others | 0.330 | 0.385 | 0.440 |
In the 44 games Rowand has missed, the Phils' centerfielders (mostly Shane Victorino) have slightly outslugged Rowand, hit much better, and massively outperformed Rowand in getting on base. In total, the non-Rowand centerfielders have an OPS that is 0.079 higher than Rowand's. That's a signficant difference at the plate.
How about in the field? Isolating one player's defensive contribution is difficult, but it's possible to see how the team has performed with and without a player in the field by looking at defensive efficiency (the percentage of balls in play turned into outs). Here's the comparison with and without Rowand:
| DER | |
| With | 0.656 |
| Without | 0.702 |
Without Rowand in centerfield, the team has converted about 4.5% more balls in play into outs. That's a significant difference in performance.
Doubters will say that the team suffered for most of Rowand's time because of the wall-fearing tin-man (Bobby Abreu) in right field. They would say that the team's DER would be lower with Abreu in the outfield, thus penalizing Rowand for playing healthy when Abreu was on the field. So, let's limit the DER analysis just to games after Abreu stopped playing for the Phils (his last game was July 28):
| DER | |
| With | 0.675 |
| Without | 0.698 |
The gap has narrowed, but still, even in the post-Abreu era, without Rowand, the team's defense has been better than with Rowand by almost 2.5% more batted balls turned into outs.
The Phils have a better record without Rowand than with; their center fielder has hit better when he was not Rowand than when he was; and their defense has been considerably better without him on the field. There's no reason Charlie Manuel should let him play everyday if he returns and if the Phils's season stretches past October 1.

"... K's kill a player"
That bum Howard would really be good if he would only stop striking out so much. Maybe he should bunt more often.

I've watched pretty much every inning since Labor
His strikeout rate since then has been slightly lower than it was beforehand, and his walk rate higher. Howard has done a terrific job of laying off when he's getting pitched around. He was baffled by Ohman or whatever his name is on the Cubs, but not because he was getting pitched around.
I got just one more thing to say
If Victorino is that much better then Rowand, bat Rowand 2nd with his .323 BA and move Victorino lower in the order. Put Victorino in the 3rd spot and move Utley to 5th to protect Howard.

no, and no
I'll admit that when I saw Dave posting the records with and without Rowand, my first thought was, "That speaks against Abreu, too." Just as post hoc ergo prompter hoc applies for the Abreu deal, it also applies to invalidate the idea that the ballclub is better simply by virtue of not having Rowand in the lineup...
...if there's no other evidence to back up that idea. The difference between what Dave has done here and what you and other Abreu-bashers keep doing, is that he offers a whole bunch of other data against Rowand as a contributor.
Now, if you're limiting your case to "Rowand > Roberson," I'm 100 percent with you. If you want to pull Burrell out of the game for defensive reasons, or because he's not a good contact hitter, I'd rather see Rowand in there than Roberson, or Bourn, or (since Manuel sometimes seems to believe he's an outfielder) Thurston. Rowand's defense may or may not be better than either of the rookies, and he's not as fast afoot, but I trust his bat a lot more and I'm willing to credit his "intangibles" as maybe meaning something, especially after Bourn got picked off late in a game a week or two ago.
But unless Vic'o is hurt worse than he seems to be, there's just no way Rowand should be in the lineup over him. Perhaps he should play vs. lefties rather than Dellucci... but would you rather have him in there than Conine the Barbarian? I think not.
Just say no to Rowand, indeed.
I never mentioned Conine

You don't get it
However, as dajafi points out, I went further and tried to explain the difference. First, the guy replacing Rowand, mostly Victorino, has significantly outperformed Rowand at the plate. That's one way to explain the positive difference in Rowand's absence. Second, the team defense has been significantly upgraded without Rowand. That's not all Rowand's absence, obviously, but given Victorino's stellar range, it's part of it as well.
Offering an explanation and proving it is what this site is about.

No, you don't get it
If you think the reason I don't think much of batting average is because it's an average, then you're really off base.

A more detailed comparison
Rowand: http://www.baseballprospectus.com/dt/rowanaa01.shtml
Victorino: http://www.baseballprospectus.com/dt/victosh01.shtml
Burrell: http://www.baseballprospectus.com/dt/burrepa01.shtml
As one can see, Victorino has outplayed Rowand at the plate and in the field. And despite having a down year, Burrell has been a better player than Rowand (see WARP which includes offense and defense). In fact, the fielding stats demonstrate that Rowand has been overrated, Burrell underrated, and Victorino as excellent as we thought.

ey quote from initial post:
Nobody said don't play him.
There should be a "K"
Reading comprehension

maybe you need some reading comprehension
"The Phils have a better record without Rowand than with; their center fielder has hit better when he was not Rowand than when he was; and their defense has been considerably better without him on the field. There's no reason Charlie Manuel should let him play everyday if he returns and if the Phils's season stretches past October 1."
Well, I was dispute was to let him play everyday. Pitchers like Moyer, Hamels, Myers and Lieber need good defensive players. There is more to baseball then just offense. Weren't you the one who disputed that pitching doesn't win? Well it does. Rowand should play everyday and sit Burrell. That was my point. But because you are all over on Burrell which is crazy in itself. Platoon Dellucci/Conine/Burrell depending on matchups. The Phils will score runs reguardless. If you have better defense you give up less runs. that LF combo are not very good defensive players. Besides, just to point something out, Rowand has a .248 BA with RISP. Dellucci has a .194 BA and Burrell has a .220 BA.
I am not saying move Victorino out of CF, I am saying play Rowand in RF or LF depending on who is pitching and what kind of lineup the opposing team is throwing. If you are going to play in the playoffs and have to face a Padres or a Dodgers with their pitching, you have to keep the opposing teams runs down because you could have trouble scoring runs.
Dellucci has a .000 BA vs. Padres and a .200 BA vs. the Dodgers
Burrell has a .167 BA vs. and vs. the Dodgers has a .167 BA
Rowand has a .174 BA vs. the Padres and a .267 vs. the Dodgers.
Chances are the Pads will win out. None of those players have good numbers vs. the Padres. But Rowand is indeed heads above the rest defensively. So if you are going to have a hard time scoring runs, you better have a good defensive team to limit the amount of runs the opposing team will score. Don't you think?

The rest of this comment is directed at Philsin06:
I really don't want to get involved, but I've been reading this blog for a while, and I would really appreciate if before you posted, you at least READ Moneyball. You don't need to agree with a single word of it, but you should at least understand why the people who write on this site disagree with your assessments. There are basic principles illustrated in that book like batting average being less valuable than on-base percentage for simple reasons like batting average varies wildly from year to year and on-base percentage doesn't vary as much; and things like why a hitter's K totals shouldn't be taken as seriously as other statistics. Then you can feel free to argue as much as you want, but I'm annoyed that reading this blog has turned into reading a bunch of guys giving you a book report on Moneyball. You don't need to agree with a word of it, but please at least know who you're arguing with so I don't have to read book reports to enjoy this blog.
thanks MattS
I do believe there's a danger in over-concluding based on statistics; I think there are things we can't measure, either because the metrics aren't there yet (e.g. defense) or because they're simply not quantifiable (e.g. mood of the clubhouse), but that still matter, and that we limit our analysis by dismissing things just because we can't effectively measure them. But that's nothing like saying we shouldn't try to measure things; of course we should.
The 1993 Phillies, the last club from these parts to make the playoffs, are a great example of all this. The performance analyst looks at that team and sees a bunch of position players who drew tons of walks and who could and did do damage when they put the ball in play, and a bunch of pitchers with very good strikeout-to-walk ratios. The John Marzano types looks at that team and sees a bunch of personalities that meshed well, guys who sat up all hours playing cards and drinking brews and talking baseball. Of course, they're both right.
1993

that's true
The other stuff is just better copy. Maybe the key as far as advancing the debate is to figure out how to write about performance analysis as vividly as the Ring Lardner types did 70 years ago...

great book
by Carson on Sep 25, 2006 11:25 AM EDT reply actions
Is that Carson...
Also, for anyone who enjoyed Moneyball there is an excerpt from Mike Lewis's (not the Eagles safety) next book, which basically applies the same theory to the NFL.
Semi-useful link here: http://tinyurl.com/gyppc
And DC, did being dismissed as a losing team by pretty much everyone in spring training '93 motivate the individual players to up their performances that year? My own personal theory is that there are sooooo many random variables that go into each season that a true answer to the "SABR versus scrappy" debate will probably never be found. With that said, why not enjoy the debate for its own sake?
