Lies, Da#* Lies, and Statistics

After two straight convincing wins, the Twins stand at 26-18, eight games over .500 for the first time since 2010. It is early, but so far the record says "contention". The record says that the Twins have improved, but a case can be made that the whole thing is "smoke and mirrors". Statistics tell a conflicting story, but the deeper you dig, the more amazing it is that the Twins are among the top teams in the league.

 

The way you count wins and losses in this game is by the number of runs scored. The Twins are doing quite well by this simplest statistic. They have scored 204 runs and allowed 186, that is a run differential of +18, fourth best in the AL, behind Kansas City, Houston and (surprise!) Toronto. Breaking it down a bit further, the Twins score the third-most runs per game, that is very good. They are seventh in fewest runs permitted per innings pitched, so slightly above average. How they come to score that many runs and permit that few is where the smoke and mirrors comes in.

 

Let's start with the offense. In this era of limited run-scoring, no one is hitting like they did ten years ago. The Twins 204 runs in 44 games is an average of 4.64 runs per game which would yield 751 runs in a full season--the 2004 Twins scored 780 runs and finished tenth in runs scored. Minnesota's team batting average so far this year is .257, good for third in the league however, the team OBP is 11th, team slugging is 11th and team OPS is 12th. It isn't home runs, either. The Twins rank 13th out of 15 in in long balls and have given up five more homers than they've hit. Somehow, the Twins have managed to score more runs per game than all but two teams. Last year's team also overproduced when viewing their on-base and slugging. One more point, it isn't the running game or more accurately stolen bases. The Twins are in the bottom half of both stolen bases and stolen base percentage.

 

Pitching and fielding comprise defense. I don't know if it is pitching or fielding or both, but the Twins in the last four years have permitted either the most or second most runs in each of those four years. This year, eight teams are allowing more runs per inning pitched. Even more than the hitting, this result seems to fly in the face of the statistics that should support improvement. Minnesota is dead last in strikeouts, batting average against and hits allowed. They are tenth or worse in OBP against, OPS against and home runs allowed yet the team is allowing 4.23 runs per game.

 

I don't believe the positive runs differential (and 59% winning percentage) can continue with such poor supporting numbers. If the Twins are going to continue to surprise their fans, they need to erase the gap between the stats that predict run-scoring and actual runs scored. Other teams have beaten the odds for portions of seasons, but eventually the law of averages catches up. More games like the last two will do wonders for all the numbers.

Sabermetrics can be very powerful when properly applied to the analysis. The most common tools are averaged outcomes for discrete at-bats, such as OBP and SLG. As shown above, these tools indicate that the Twins are "playing above their heads".

 

In this case, a couple of particular average outcomes are not the best analytical tools because the data is too stratified. Here are two examples that skew the averaged data:

 

  • The Twins were outscored 45-16 in the first seven games of the season. The average runs per game is still skewed by this incredibly horrible start.
  • Duensing and Stauffer have been responsible for 19 runs in 19 innings. In every case (except for the first week), they have pitched when the Twins are far ahead or behind. 

I don't have the time to grind out the numbers, but refining the dataset for these two issues reduces the differential between game outcomes and play-by-play performance:

  • The underlying runs per game averages are not so different from performance after the first week.
  • Our top-line relievers are performing well and in accordance with the team's record.
  • The end of our bullpen is awful.

I do agree that the aggregate individual performances indicate that:

 

Team hitting has been unsustainably "clutch".

Ricky Nolasco has been unsustainably "lucky".

 

I fully agree that the Twins are not a 93-win team but they are sustainably average or a little better.
