Tropicana Field Finds Southpaws Sexy

This started as something else and ended weirdly. I wanted to edit the first part out, but I think the information is still a bit interesting. Maybe not.

Star-divide

Pat Burrell's Rays career is a nearing the 120 plate appearance mark. His slash line is what you would expect from him, at least until you get to the slugging part. Everyone knows we didn't bring him in to have a 0.061 ISO, and while I highly, highly doubt Burrell suddenly lost all of his power, I did go in search of similar collapses.

Carl Yastrzemski (1971) Age 31

Prior three seasons: .294/.413/.532

Season in question .254/.381/.392

Season in question:  .302/.367/.510

Next three seasons:  .279/.326/.491

Season in question: .256/.356/.485

Next three seasons: .269/.346/.542

All of these players were amongst the top 10 drops and very few recovered fully. There is some good news. Adrian Beltre is listed, but he's been a very valuable player, and part of the reason for his change is the ballpark he plays in. J.D. Drew had a rough 2002. Reggie Jackson is listed twice in the top 25, about 13 years apart.  And so on.

Even if you are extremely pessimistic about Burrell and think he'll become the biggest drop in history, that's around -0.160, meaning his ISO will raise 0.030 points the rest of the way. ZiPS says .205 the rest of the way and .163 overall. Given the missed month and impeded presence of a stiff neck for most of the first month, that seems fair.

Let's go back to Adrian Beltre for a moment. I mentioned his home park, Safeco Field, hurting him. You see, Safeco suppresses right-handed power and Beltre is...you guessed it, a right-handed power hitter.  Could Tropicana Field have a similar effect on right-handed hitters?

Look at a few of the career Rays and their home/away splits:

                Home                                    Away

Iwamura: .298/.374/.404               .269/.340/.387

Crawford:  .306/.343/.450             .285/.324/.422

Longoria:  .263/.337/.525              .304/.379/.573

Upton:  .261/.354/.407                   .276/.364/.411

Only four cases but the lefties hit better at home and the righties hit better on the road.  How about for Carlos Pena?

2007       .305/.425/.678                   .261/.398/.580

2008       .254/.408/.504                   .240/.347/.484

Most players hit better at home, so that's not a huge surprise. The split dynamic at work here is a bit of a surprise though. The Trop has equal dimensions to left and right center, and down the left field line is actually a few feet fewer than down the right field line.  Maybe it has something to do with the AC unit or whatever. Baseball Musings day-by-day database allowed me to compare hitters throughout Rays history at home versus on the road. I chose to use the last three seasons (meaning 2006-2008).

On the road

LHB .256/.327/.417

RHB .260/.319/.416

At home

LHB .271/.349/.441

RHB .259/.328/.429

Not quite as exaggerated as the individual splits made it out to be. Right-handed batters gain 0.022 OPS points at the Trop compared to their road voyages and left-handers gain 0.046 OPS points. I checked the entire ML seeing what the average home/road split was and found this:

2008: 0.039 OPS points gained

2007: 0.027 OPS points gained

2006: 0.033 OPS points gained

From there I compared all the hitters who played at the Trop in a road game:

LHB .269/.340/.433

RHB .262/.332/.421

Those same batters, at home, versus the Rays:

LHB .289/.364/.458

RHB: .286/.349/.463

No surprise. The Trop has been a pretty neutral park for the most part, so gaining OPS points on the road is nothing new. Lefties gained 0.049 OPS points at their home parks and righties gained 0.059.

Left-handed hitters are better at the Trop. Why? I don't know. This shouldn't mean the Rays go out and field nine lefties everyday because, well, they can't.  Matt Joyce, Carl Crawford, Reid Brignac, Carlos Pena, and any number of switch hitters work, but you can't put a left-handed thrower at very many positions.

Some are going to use this information against the Rays signing of Pat Burrell, but hey, they tried signing Bobby Abreu, Jason Giambi was almost certainly Oakland bound, and Adam Dunn is in denial of his own defensive limitations. I don't think the splits should be enough to say "TRADE EVAN LONGORIA FOR AN EQUALLY TALENTED LEFT-HANDED BAT PRONTO!", but when the Rays look to add a hitter, say a catcher, it's probably going to be worth their while to look for one who bats left-handed. Like, say, Jeff Clement.

I was thinking of something along the lines of Brignac for Clement this morning

After looking at it I think we would be getting hosed, but the M’s don’t use the guy and are horrible at SS.

Rays Win!

Completely OT, but I wanted to get some opinions

Has anyone seen THIS:

Have we really been this unlucky, that we have the best 3rd order winning percentage in the league? Am I raeding this wrong?

Rays Win!

by Sandy Kazmir on Jun 15, 2009 6:50 PM EDT reply actions   0 recs

Our expected record is 40-25!!

That’s a .615 winning percentage

Rays Win!

They've been regressing since May 1st...

They were 8-14 through April

They are 26-17 since… That’s .604 WP or a team that wins 97 games.

You can’t really hope for anything more…

Kick in HARDER!

We just need to stay healthy now. That will help a lot.

Yeah we've been playing pretty well.

It would look even better right now if the town of Cleveland didn’t have a damn hex on this team.

Whatever

I hope LBJ resigns then breaks his leg and tears his ACL

This is deceptive.

Their May record was only 1 game over .500 for the month of May. Only this recent streak in June has indicated that they’re regressing.

Wouldn't this data be explained based on the fact that the Rays do not throw very many left handed starters?

Lefties usually hit righties better. The Rays have historically mainly thrown righties. The past couple years the only lefty we’ve thrown has been Kaz (and hes been bad or hurt). In 2007 we had Kaz plus Howell and Fossum (not exactly quality). Fossum again in 2006, but then again we threw a bunch of righties that any quality MLB lefty would pound. So lefties had a pretty big advantage there.

Then righties had the disadvantage of facing on average 4 righties while our best pitcher was a lefty. Of course they had a field day with the Fossum era.

The Matt Williams season in question is hardly a collapse

Higher average and OBP, still slugged over .500

Am I missing something?

I miss Chad God
