What makes Teams Win- Offense?

Most wins; third most runs

Yesterday we discussed what statistic has the biggest impact on a pitcher's ability to win and determined that the better a pitcher's ERA, the more wins that pitcher was likely to have. Today there is going to be a similar topic, what makes a team win. Today will focus on the position players while tomorrow will be pitching. The statistics that will be compared to wins today are Runs, Strikeouts, Stolen Bases, Batting Average, On Base Percentage, and two metrics from fangraphs.com that measure fielding and baserunning. The stats will be listed from greatest correlation to worst correlation.
1. Runs
Not much to be surprised by here, games are decided by runs so it's likely that the more you score, the more you win. What is a little surprising is that the Washington Nationals had the most wins in MLB last year, 98, but came in 10th in runs with 731. The Rangers, who led the majors with 808 runs won 93 games. The Terrible Houston Astros only won 55 games, worst in the league, and only had 583 runs, worst in the league.

2. On Base Percentage + Slugging
Hailed as the super stat among players OPS has a .49 correlation for team's wins. The Yankees were the league's most patient and powerful hitters with an OPS of .790 and won 95 games. The Rockies pitching was horrible and that prevented the team from having a good season despite their offenses .766 OPS which ranked them third in the league. The Nationals placed 8th in the league with an OPS of .750.

3. Fielding Metric
There is the saying that defense wins championships and it shows to be somewhat true as the World Series Giants had the 10th highest fielding measuring in at 13. The Braves, who lost in the Wild-Card showdown had a fielding metric of 58.6 and won 94 games on the season. The Red Sox, who only won 69 games, were a surprisingly strong fielding team (34.6).

4. On Base Percentage
Hailed as the wonder stat by the Moneyball generation (then replaced by OPS), OBP does a fine job predicting winners but falls just behind Fielding. The Cardinals and the Yankees were the top two teams and reached 88 and 95 wins respectively. The Athletics, who had 94 wins had an OBP of only .310, bad enough for 24th in the league. The Marineers, who had a league worst .296 OBP, had 75 wins.

5. Batting Average
The first recorded statistic for batters means a lot less than expected with a correlation of .268. The Cardinals had the highest batting average in the league and the Yanks placed second. The Tigers, who were the runner ups in the World Series, had the third highest batting average at .268. The Nationals were not that strong of a hitting team only coming in at #12.

6. Baserunning
Actually has almost no correlation at all coming in at .10. Strikeouts and Stolen Bases actually have a higher correlation rating but there are the opposite of what was expected. Strikeouts actually had a positive correlation while stolen bases had a negative. The Angels had the best Baserunning rating and finished with 89 wins, but on the other end of things the Nationals came in last and led the majors in wins.

7. Strike Outs
This actually shows that the more a team strikes out, the higher their chances of winning are, but ever so slightly. The Athletics led the majors with 1387 strikeouts but still had 94 wins. In second was the Astros who only had 55 wins. The team with the least amount of strikeouts, the Kansas City Royals who had 72 wins.

8. Stolen Bases
Alright, this actually has a stronger correlation than strike outs but it is the opposite correlation of what we want. Teams are better off stealing less because the more you steal, the likelier you are to get thrown out and lose a runner. The Brewers led the majors in with steals and had 83 wins while the Orioles were last with 58 steals but won 93 games.

What Makes A Pitcher Win?

Gio Gonzalez led the majors with 21 wins lat year
One of the first recorded statistics in sports was the pitcher's win, but where do those wins come from. Today we will look at what statistics correlate the most with wins. There has been a bit of a movement recently to stop considering the win an important statistic due to factors like run support and defense. But is it possible that wins come from stats like ERA and strikeouts already, and that there is no need to discount wins, but rather view them as the culmination of other statistics. The statistics that will be compared to wins today are ERA, K/9, K/BB, AVG, WHIP, BABIP, tERA, and Fastball Velocity. Stats appear in order of Correlation. 88 pitchers who qualified for the ERA tile were used in this study.
1. (ERA Earned Runs/ IP)x9
I cannot say that I am overly surprised with this one considering that it, along with wins and strikeouts, is one of the numbers in the pitching triple crown. Gio Gonzalez led the majors with 21 wins last year and had the 9th lowest ERA at 2.89. Clayton Kershaw, who led the majors with a 2.53 ERA had 14 wins. The biggest wrench in the data was Cliff Lee, who was last among the 88 pitchers with only 6 wins, but his 3.16 ERA was 15th overall. It earned the number one spot with a correlation of .64351.

2. WHIP (Walks + Hits)/ Innings Pitch
Clayton Kershaw again led the majors in this category with a 1.02 WHIP. Gonzalez placed 12th at 1.13. Jake Peavy and Cliff Lee threw curveballs in this category both placing in the top 10 but Peavy only had 11 wins and as said earlier Lee had 6. The correlation was -.55608.
3. True ERA ERA adjusted for Defense and other variables
Should have had more than 14 wins
Coming in third with a correlation of -.53644, tERA was led again by Clayton Kershaw who had a terrible offense in LA. Gio Gonzalez placed fifth with a tERA of 3.34 and Cliff Lee showed up again screwing up the data with the third lowest tERA. Jeremy Guthrie, who only had 8 wins, had the highest tERA of the 88 pitchers with 6.33.
4. Batting Average Against
Gonzalez led the majors with a .202 BA against so that might make you think that this should have the strongest correlation. Another reason that this might be seen to have a high correlation is that Cliff Lee and his 6 wins doesn't show up until 55 on this list. The problem with this is that most of the data is spread throughout with Nationals' Edwin Jackson and Ross Detweiler taking 22 and 23 with 10 wins and BA of .237.
5. Strikeouts per 9 innings
There was a huge dropoff here going from a -.52691 correlation to a .295676 correlation for K/9. Max Scherzer led with 11.08 and had 16 wins. Yu Darvish was second with 10.4 and also had 16 wins. Gonzalez was third in K/9. Clayton Richard had 14 wins but only had 4.4 K/9.

6. Batting Average Against on Balls in Play
This stat is often used to project how a player will do in following seasons or how a player will do whe traded to a new team  but it does not correlate that well with wins. In fact, the correlation is only -.27. Jared Weaver led the majors with a .241 BABIP and as second in the league with 20 wins. However, Ervin Santana, who was second in BABIP, only had 9 wins.
7. Strikeouts/ Walks
This stat really seems like it should be a strong indicator of who wins or loses but the the pitchers with the highest two K/BB, Cliff Lee and Joe Blanton only had 6 and 10 wins respectively. This again is just because Cliff Lee had a terrible offense in Philadelphia, at least when he pitched. Gonzales doesn't appear til 46 on the list, having a K/BB of 2.72.

8. Fastball Velocity
Proves You Don't need to throw hard to win
This only has a correlation of .09 and that is really to be expected. We should all know that wins has very little to do with how hard you throw the ball, but how you make it dance and where you put it. It doesn't hurt necessarily as David Price had the hardest fastball in the majors with 95.5 MPH and had 20 wins. Jeff Samardzija had the second fastest fastball but only 9 wins, mostly due to the Cubs sucking ass. Gio's fastball averaged 93 MPH. Knuckleballer RA Dickey had 20 wins with a fastball of only 83.4 MPH.

Using PER to rank the major league bullpens

despite the #1 bullpen, the rays were unable to
make the playoffs
It is commonly known that a good bullpen is a key to a strong season. Now that the season only has one day left I believe that now is a fair time to assess each team's bullpen for the 2012 season. According to PER , Hawks Report's new metric, PER, 7 out of the top 10 best bullpens in baseball have reached the playoffs. The number one bullpen in baseball , the Rays,are out of the Wild Card Showdown by 3.5 games before the last games end . The Diamondbacks also find themselves in the top 10 at spot number 6, they werable to finish 6 games out of the wild card despite also having one of the better offenses in the game. The three playoff teams that were outside the top 10 were the Cardinals (16), Tigers (19), and the Giants (25). Here are your 2012 team bullpen PER rankings. Teams in yellow have clinched the wild card,, blue have clinched the division, and orange have clinched a playoff spot.

Introducing Pitcher Efficiency Rating (PER)

I do not claim to be a great sabretician and I understand that this formula might have been created by someone else without me being aware and that is the case then I am sorry. Pitcher Efficiency Rating is a very simple formula and is just innings pitched/total batters faced. As you would expect, the best pitchers lead this category so there are very few players that jump out of nowhere but I think it helps sort out who is the best among the best. If you would combine both relievers and starters for this statistic you would find that the 10 rated pitchers are relievers while the first starter to appear in this rating would be Jered Weaver at #11. Here we take a look at the top 15 starting pitchers in baseball:
Player Team Efficiency Rating
Jered Weaver Angels 0.255737705
David Price Rays 0.252392344
R.A. Dickey Mets 0.251605759
Clayton Kershaw Dodgers 0.251376147
Matt Cain Giants 0.249824971
Cliff Lee Phillies 0.249695493
Justin Verlander Tigers 0.249058577
Chris Sale White Sox 0.248704663
Felix Hernandez Mariners 0.248571429
Cole Hamels Phillies 0.248096886
Jake Peavy White Sox 0.246783626
Mike Minor Braves 0.246016484
Hiroki Kuroda Yankees 0.245886443
Madison Bumgarner Giants 0.245111896
Jason Vargas Mariners 0.24475761
Jered Weaver comes in as #1 in PER
There are no real surprises in that list other Jason Vargas and Mike Minor, neither of whom appear in the top 40 of ERA. This can be accounted to weak defense although I doubt that is the only reason. Johnny Cueto, who is #7 in ERA, falls just outside the top 15. David Price has the best ERA but Jered Weaver beats him out in the Efficiency Rating. This should be no surprise considering Weaver is considered by many as the best pitcher in baseball. Now let’s take a look at the top 10 relievers in baseball.
Player Team Rating
Craig Kimbrel Braves 0.269604
Fernando Rodney Rays 0.264855
Casey Janssen Blue Jays 0.260426
Brad Ziegler Diamondbacks 0.258594
Kenley Jansen Dodgers 0.258333
Jake McGee Rays 0.257767
Aroldis Chapman Reds 0.257143
Kris Medlen Braves 0.256398
Jason Motte Cardinals 0.255839
Sergio Romo Giants 0.255189
Former Dominican Catcher
and current Dodgers closer Kenley
Jansen is one  of the top relief pitchers

Again, there are no surprises here as Craig Kimbrel, probably the best closer in baseball heads the list. The Rays and Braves seem to have the best the best bullpen as they both have two of the top relief pitchers according to efficiency rating. For full ratings you can check out these links.
