New Line of Work

Since I'm bored at work today, and since I'm somewhat on the prowl for a new job, I thought I'd explore my talents in other areas. Today I'm going to try my hand at wizardry. For my first trick, I'm going to take your average, everyday Rookie of the Year, and transform him into Babe Ruth before your very eyes. Now the reason I chose to use Ryan Braun for my magic trick is because Baseball Prospectus looked at his splits from last season. I didn't even realize until I read the article how much he destroyed left-handed pitchers. So one thing led to another, and before I knew it, I had filled a spreadsheet with data. Now, the calculations I did would have looked even more insane had I done my Ruthian transformation on Babe Ruth himself... okay, I'll get to that in a minute. Meanwhile, check out how I changed the Hebrew Hammer (or as BP calls him, the Scourge of Southpaws) into the Sultan of Swat:

First I looked at his splits from last season:
Against RHP: 364 PA, .282 BA, .319 OBP, .526 SLG, .845 OPS, 19 HR, 18 2B, 4 3B, 62 RBI
Against LHP: 128 PA, .450 BA, .516 OBP, .964 SLG, 1.480 OPS, 15 HR, 8 2B, 2 3B, 35 RBI

Those numbers against lefties raised a few eyebrows. Then I decided to have some fun. I did the same thing with Ryan Church in a previous post ("Church v. Hunter," from November 30, 2007); I expanded his numbers against lefties to the full season. Last year, Ryan Braun had 492 plate appearances. Here's how they would have looked if they were all against lefties:

492 PA, .450 BA, .516 OBP, .964 SLG, 1.480 OPS, 192 Hits, 58 HR, 31 2B, 8 3B, 135 RBI

That would probably be the greatest offensive season of all time. Now, let's have some real fun. Baseball-Reference has a tool that allows you to see how a player would perform under different circumstances. The two free options are to see the stats were the player to play in an extreme pitcher-friendly environment, Dodger Stadium in 1968, or in an extreme hitter-friendly environment, Coors Field in 2000. Here's how Braun's 2007 would have looked had he played all 113 of his games at Coors in 2000:

481 AB, .366 BA, .414 OBP, .715 SLG, 1.129 OPS, 176 Hits, 31 2B, 7 3B, 41 HR, 128 RBI.

That looks like an MVP season to me. But wait, there's a lot more. What would happen if those stats were expanded to a full 162 game season:

689 AB, .366/.414/.715/1.129, 252 Hits, 59 HR, 44 2B, 10 3B, 184 RBI.

Again, that would be one of the best seasons of all time, among the top three seasons of hits, extra-base hits, total bases, and RBI.

Finally, let's complete the transformation and look at Braun's stats in 2000 at Coors Field were he to have every one of those at-bats against lefties:

689 AB, .509 BA, .577 OBP, 1.087 SLG, 1.665 OPS, 351 Hits, 107 HR, 54 2B, 13 3B, 272 RBI.

Tada!!! Wow. That's actually double what a fairly normal MVP season would be. That was a lot of fun.

I would LOVE to do the same thing for Babe Ruth, but unfortunately baseball-reference.com doesn't have splits that go back that far. But in case you were curious, I'll put his stats from his best seasons and for his career were they all to take place at Coors in 2000:

1921: 601 AB, .408 BA, .544 OBP, .913 SLG, 1.457 OPS, 245 Hits, 71 HR, 53 2B, 19 3B, 217 RBI
1927: 605 AB, .398 BA, .532 OBP, .863 SLG, 1.395 OPS, 241 Hits, 75 HR, 36 2B, 10 3B, 225 RBI
Career: 9608 AB, .386 BA, .521 OBP, .776 SLG, 1.297 OPS, 3712 Hits, 908 HR, 662 2B, 181 3B, 3133 RBI.

Terrifying.
