By the Numbers: Evaluating the Impact of Cubs and Sox Hitters

Bryan Lahair has been the most valuable Cubs hitter this season.

Paul Konerko has been the most valuable White Sox hitter this season.

It is almost overwhelming how many statistics there are to evaluate baseball players. Outside of your typical fantasy baseball categories, there are advanced statistics used to evaluate the individual’s, or team’s, hitting, pitching and fielding abilities, as well as sabermetrics used by front office people and baseball junkies to determine the true value of a baseball player (such as wins above replacement).

As we prepare for a long summer of Chicago baseball, I realize there’s probably not much to look forward to in terms of the immediate future of both the Cubs and White Sox. However, considering the Bulls season is now over and the Bears have yet to start training camp, I have to find a way to keep myself (and you guys) entertained. Therefore, instead of assessing crazy baseball statistics, I found a way to evaluate the every day hitters of our baseball teams, thinking that it may at least give us some hope for the future and/or make us want to pull our hair out.

In 1979, Bill James (the inventor of sabermetrics and a statistical god within the baseball community) developed a Runs Created Formula in an attempt to compute the number of runs “created” by a hitter throughout the course of a season (refer to the book Mathletics). In other words, if a team consisted of nine of the same player (nine Paul Konerkos, nine Starlin Castros, etc.), approximately how many runs would they have scored thus far this season and, more importantly, how many runs would they score per game? In order to figure this out, I gathered each player’s statistics and computed the runs created for each hitter using:

Runs created = ((hits + BB + HBP) X (Total Bases))  ÷   (AB + BB + HBP)

This metric alone, however, doesn’t necessarily give us an idea of how truly valuable a player is to his team. The problem with any runs created metric is that a bad hitter with a lot of plate appearances might create more runs than a great player with less plate appearances. In order to fix this problem, we must factor in outs. According to Mathletics, “Approximately 1.8% of all at bats result in errors. Hitters also create ‘extra’ outs through sacrifice flies (SF), sacrifice bunts (SAC), caught stealing (CS), and grounding into double plays (GIDP).”  Therefore, “game outs used” can be calculated with this equation:

Game outs used = .982(AB) – hits + GIDP + SF + SAC + CS

By dividing that number by 26.72 (the total number of game outs available in a game, taking into account the .018 approximate number of errors per 27 outs in a MLB game), I was able to determine the number of games’ worth of outs that have been used by each batter.  That leaves this equation as the final step:

Runs created per game =  runs created  ÷  games’ worth of outs

Below are the numbers for each Cubs and Sox every day hitter:

As you can see, the numbers don’t lie. Anyone who follows and watches the Cubs and/or Sox knows that their two most valuable hitters thus far have been Bryan Lahair and Starlin Castro, and Paul Konerko and Adam Dunn, respectively. Ironically, I already wrote posts about Lahair, Dunn, and Konerko and the amazing success they’ve had this season (or in Konerko’s case, his career).  Castro is only 22 years old, but he’s already one of the best pure hitters in baseball. He has an incredible knack for making contact, even on balls out of the strike zone (think Vladamir Guerrero). The reason his runs created per game number is not as high as you would think is because of his inability to walk and lack of power. But again, he’s only 22 years old. The kid will continue to improve and get stronger as he gets older. The walk and home run numbers will only go up. He has an extremely bright future.

Although that’s all great to look at, I can’t help but focus on the two names at the bottom of the Cubs list: Alfonso Soriano and Geovany Soto. To put into perspective how disappointing these two players have been (and disappointing is a severe understatement), look at their numbers during their best seasons as Cubs players:

We can all agree, even before seeing this, that Soriano is an absolute joke. I can sit here and shred him to pieces if I really want to, but after all these years of extreme frustration, it’s not even worth my time anymore. He’s an atrocious baseball player, and to think that he was a 40/40 player (40 homers/40 stolen bases) only 6 years ago when we signed him nearly makes my head explode. In his first season as a Cub (consequently his best), Soriano created over 4 runs per game more than he does now. Amazing. And you know what else is amazing? Bryan Lahair creates 3.77 runs per game more than Soriano this season. What are their salaries, you ask? Lahair is currently getting paid $482,500 in his first season as a 29-year-old. Soriano, who is only five years older, is making $18,000,000. This means that Soriano is being paid 37 times as much as Lahair, yet Lahair is rated as being 8.26 runs better per game than Soriano. That truly upsets me. But, as we all know, athletes get paid for past performances. Every contract in baseball is guaranteed. Some Cub fans seem to think he will eventually get his act together over the next few years. And for whoever does think that, let me take away whatever it is you’re smoking and tell you this: no he won’t. He will never even be a third of the player he used to be. End of story. Too bad the next two and a half years can’t come any sooner.

You think I’m going to let Geovany Soto off the hook? C’mon man. There’s one word to describe how pathetic he’s been the past couple of years: EW. What in the world happened to this guy? Not only was Soto an All-Star in 2008, but he also won NL Rookie of the Year AND finished 13th in NL MVP voting. I don’t have an answer for his shocking lack of production since that great season, but I wish I did. The fact that he’s creating a team worst 2.24 runs per game (only factors in every day players) compared to 6.73 in 2008 speaks for itself.

As for the White sox, Paul Konerko has obviously had a great season, as he continues to be the most valuable hitter in their lineup year in and year out. Alejandro De Aza has been a pleasant surprise. He certainly didn’t have the highest of expectations coming into this season, but he has proved to be worthy of an everyday starter in center field – something the Marlins didn’t give him a fair chance to do. And after signing a fat 4-year, $32.5 million extension last winter, Alexei Ramirez is continuing to disappoint. For the number of at bats he’s had (leads the team), he has been arguably the worst hitter at his position this season – just horrendous.

I know I already praised Adam Dunn the other day for how great he has been this season, so I’m not going to get into it again here. Comparing this season’s numbers to last season, though, is really incredible. You can look at his 2011 numbers below:

Dunn’s creating 5.94 more runs per game in 2012, and he has created almost as many runs in seven weeks this season as he did ALL of last season. What a turnaround. Good for him.

As I said earlier, there are so many ways to measure the value of Major League players. Using runs created is a little more unique than most and has proven to be very accurate. This metric shows us how truly valuable players like Bryan Lahair and Alejandro de Aza have been, and hopefully will continue to be, this season. It also shows us how disappointing every day players like Geovany Soto and Alexei Ramirez have been thus far. But regardless, there are nearly 130 games left to play. There’s more than enough time for improvement – or not. We can only hope for the best.
