Orioles Line-Up With Platoon Splits

With the roster projections more or less done, I thought I'd update the line-up post I did previously with platoon splits. This uses each player's career numbers and then regresses (with righties expected to have a slightly smaller split than lefties).

Player Projected wOBA
Overall vs. LHP vs. RHP
Matt Wieters .324 .311 .330
Derrek Lee .340 .358 .335
Brian Roberts .335 .319 .342
Mark Reynolds .342 .361 .335
JJ Hardy .318 .337 .311
Luke Scott .355 .332 .362
Adam Jones .337 .343 .334
Nick Markakis .361 .342 .370
Vlad Guerrero .346 .363 .340

I don't have it weighted by plate appearances, but the overall marks for the team seem pretty even versus righties or lefties (~.340 for both).

Wieters and Roberts - despite being switch-hitters - have been more like lefties in their careers. Because of that, it's entirely possible that batting Roberts lead-off against south-paws isn't the right move, though the last couple years he has been better versus them than against righties. Adam Jones has a fairly large reverse split for his career (.300 wOBA vs. LHP, .338 wOBA vs. RHP), but regressing makes it go the other way slightly.

Assuming Roberts is locked into the one spot (and if Brian can't go, I agree with Heath that Cesar Izturis shouldn't be batting above 8th ever, if even that high), the line-ups could shake out like this:

Against right-handed pitchers:

Brian Roberts
Nick Markakis
Vlad Guerrero
Luke Scott
Derrek Lee
Adam Jones
Mark Reynolds
Matt Wieters
JJ Hardy

Guerrero, Lee, Jones, and Reynolds are all more or less interchangeable (and Wieters isn't that far off). Batting Reynolds third to leverage his home runs might be a plus, but I can't see Buck not having Vlad somewhere in the middle there. Roberts-Markakis-blank-Scott definitely looks like the correct alignment versus righties. Actually, putting Felix Pie in left-field (.319 wOBA overall, .325 versus righties) and moving Luke Scott to DH might not be a bad idea, as the difference in batting between Felix and Vlad versus right-handed pitchers is only ~8 runs over 600 PA, while the difference in defense between Pie and Scott in left is close to that.

Against left-handed pitchers:

Brian Roberts
Derrek Lee
Mark Reynolds
Vlad Guerrero
Nick Markakis
Adam Jones
JJ Hardy
Luke Scott
Matt Wieters

Though switching Markakis and Lee wouldn't be too awful, and would keep the top of the line-up more "normal" looking, it isn't necessarily optimal (despite many people think Nick handles lefties exceptionally well, his regressed platoon split is only a little better than average). Relievers show up in most games though, so not making huge changes is possibly for the best. And I can't see Hardy being above Scott in the line-up regardless, but with the difference between the two being small I assume Luke would be a spot or two higher.

With Brian Roberts in Limbo, A Way to Cushion the Blow

With Brian Roberts in and out of the lineup this spring, you can't help but be concerned for the offensive prospects of the Orioles this season. There are plenty of mistakes to be made when considering who to bat leadoff should Roberts not be available for the regular season.

Unfortunately, many managers overvalue speed and base running ability when choosing a leadoff hitter. They seem to forget that none of that means much unless the leadoff man.

Can you imagine the team batting Cesar Izturis in the leadoff spot for a significant portion of the season and how damaging that would be to the offense? Before you start to think that batting Izturis leadoff is so ridiculous that no manager would do it, consider this breakdown of Izzy's career and where he and his career .296 OBP have hit in the lineup:




He has hit leadoff more than he has hit 9th or 8th individually. And he's batted 2nd quite a lot too. There are enough managers out there with big league jobs who looked at Izzy and said, "That's a guy I need at the top of my lineup." It has happened and can happen. When you lose a player who embodies the classic leadoff hitter like Roberts, there is an enormous opportunity to do something stupid.

And it can lead to disaster. To demonstrate, using the Lineup Analysis tool at Baseball Musings, I created a probable and pretty traditional lineup with Brian Roberts at the top of the order.


That lineup will score you 5.127 runs per game or 830 runs over the course of the season.

Now, place Cesar Izturis in the leadoff spot and you get 4.877 runs per game or 790 runs per season. In 2010, that difference would have been enough to drop your offense from second in the American League to sixth.

Here's a quick list of the internal "traditional" options and what happens when each of them bats leadoff:

R/G   Total Runs
Izturis   4.88      790
Andino    4.90      795
Hardy     4.92      797
Harris    4.95      801



(In the Hardy leadoff scenario, Izturis is also batting 9th...)

However, leave Izturis in the lineup (he is the most likely to play second base if Roberts can't, at least to start the season) but try a different configuration.

I have recently become more strident in my assertion that Nick Markakis has the skills to be a prototypical leadoff hitter. Let's give him a shot here. And instead of a guy in the 2 hole who "is a good bunter" or "can move the runner along", let's put a decent hitter there. A guy like Luke Scott who can get on base at a fair rate and actually drive in the leadoff man.




That lineup will get you 805 runs for the season. Even choosing the worst possible offensive option at second base, with Markakis and Scott at the top of the lineup, it beats every other option available.

The loss if Roberts will still hurt but it can be mitigated if you assess the skills of the players in your lineup correctly and construct your lineup accordingly...it doesn't have to be a disaster. Now we'll see if Buck can navigate his way through the pitfalls.

A Quick Excercise In Lineup Optimization...

A quick look at lineup optimization and how it could be used on the projected 2009 Oriole lineup.

________________________________________________
I'm stealing this idea from Beyond the Boxscore but I don't think they are in any hurry to do this exercise with the Orioles so I'll do it here.

It's all about optimizing lineups, getting the most bang for your buck out of the players that you have. I think batting order is very overrated when it comes to run production (I think Sky at BtB has said the same thing) but it is interesting to see how unorthodox a lineup can look and, theoretically, score more runs per game.

Like BtB, I'll be using the standards found in The Book: Playing The Percentages in Baseball as well as David Pinto's lineup tool found at Baseball Musings.

Here are the main players for the Oriole lineup and their CHONE projections for OBA and SLG for 2009:


OBA SLG
B. Roberts .359 .423
M. Mora .328 .414
N. Markakis .376 .474
A. Huff .354 .466
L. Scott .352 .462
A. Jones .337 .444
G. Zaun .313 .355
F. Pie .320 .407
C. Izturis .287 .326




Using the rules, the first step is to identify the top three hitters on the team. For the Orioles, that projects to be Brian Roberts, Nick Markakis and Aubrey Huff. These guys will take up the top three spots in the lineup.

For leadoff, OBP is king. You also want the batter with the least power among those three elite hitters on the team. Speed is icing on the cake. Hello, Brian Roberts.

In the two hole, it's the best hitter between Huff and Markakis. This hitter comes to bat in more big situations than any other hitter in the lineup. #2 belongs to Nick.

Cleanup should be one of the best hitters on the team and the guy with power. This would be Huff. You could quibble that Markakis may have more raw power next season and you could swap the two without much argument from me. But Huff is #4 for now.

The next two best hitters on the team are Adam Jones and Luke Scott. More value is gained in the 5 slot with a batter who hits singles, doubles and triples rather than living and dying with the home run. Scott doesn't live and die with the homer but Jones is probably a more well-rounded hitter is this regard. Scott goes to #3 and Jones is #5.

Melvin Mora, Gregg Zaun, Felix Pie and Cesar Izturis are left. From here, the order goes from best hitter to worst with a caveat that if you have someone who can steal bases, they add some value in the 6 hole. Only Izturis is a fair stolen base threat at this point in his career but the bat is so bad that I don't think he will leverage that skill too often. Mora is the best of what's left, followed by Pie, Zaun and Izturis.

Your "optimized" 2009 Orioles lineup:

1 Roberts
2 Markakis
3 Scott
4 Huff
5 Jones
6 Mora
7 Pie
8 Zaun
9 Izturis

Plugging this information into the Lineup Optimization Tool, this lineup is estimated to score 4.885 runs per game. If you swap Huff and Markakis, the total is 4.879 so I was barely correct with Markakis in the 2 hole.

Pinto's best lineup? It scores 4.898 runs per game.

1 Roberts
2 Markakis
3 Jones
4 Huff
5 Scott
6 Pie
7 Zaun
8 Mora
9 Izturis

Mora and Pie, as well as Scott and Huff are interchangeable with the same production.

One wrinkle: what if we add Matt Wieters? Wieters' CHONE: .349 OBA and .439 SLG.

Wieters would fit in at the 5 slot and bump everybody down:


1. Roberts
2. Markakis
3. Scott
4. Huff
5. Wieters
6. Jones
7. Mora
8. Pie
9. Izturis


Just the addition of Wieters...brings the runs per game up to 5.031

Pinto adds this lineup for a runs per game of 5.041 moves Wieters to number three.

How about the run production for a "traditional" lineup?

1. Roberts
2. Mora
3. Markakis
4. Huff
5. Scott
6. Zaun
7. Jones
8. Pie
9. Izturis

This configuration gives you a runs per game of 4.857.

Swap Wieters in for Zaun in the 6 spot? That gets you 4.999 runs per game.

Difference in runs per game using The Book rules vs. the traditional approach: .028

The Book vs Pinto? Pinto wins by .013

The Book vs The Book with Wieters? Wieters improves the rate by .146 runs per game.

Traditional vs. Traditional with Wieters? Wieters adds .142 runs per game.

Conclusion? I would love to see a team try one of these non-traditional lineups sometime but as you can see, it matters little. I suppose it might let you win a game or two over the course of a season which could be a facotr in a close race

But adding a better catcher? It improves jumps by at least a factor of 5.

So improving the actual members of the lineup means far more than the shuffling of said lineup. Go figure...
