Believe it or not, one of biggest factors in any offensive comparison is defensive position. Let’s take two of the top contenders for the American League Most Valuable Player: Mark Teixeira and Joe Mauer.
Both have had extraordinary seasons. Teixeira has a .939 on-base plus slugging percentage, while Mauer has a 1.071 OPS. The gap between the players shrinks because Teixeira owns superior bulk, having contributed at that high offensive level in 523 plate appearances over 114 games, versus 405 plate appearances and 92 games for Mauer.
Defensive position makes a huge impact on this comparison. American League first basemen have averaged an .837 OPS this season. Teixeira tops that figure by 102 percentage points. AL catchers own a .726 OPS. Mauer exceeds the average by 345 percentage points. His production relative to position surpasses Teixeira by 243 points.
Any time a hitter posts big offensive numbers at catcher, second base, shortstop or center field, he provides immense value to his team. Why? Offense is less abundant at these defensive spots. So assuming the player fields his position adequately, his team gets superior offense where most teams get far less production.
Since team performance plays a role in MVP selections – and the Twins are a long shot to make the postseason – Mauer may not win the award. But his offensive value far exceeds Teixeira’s at the moment.

What Core Numbers Don’t Reveal
On the surface, Ricky Nolasco’s statistics (8-7, 4.86 ERA) make his season look far worse than his strong 2008 campaign (15-8, 3.52). Believe it or not, he has actually pitched better this year than last.
Nolasco has struck out 23 percent of the batters he’s faced in 2009, compared to 20.9 a year ago. In fact, he has a chance to become the first Marlins ERA qualifier to strike out over a batter per inning. He’s also allowed home runs less often than during 2008. Although his rate of unintentional walks has risen, Nolasco has fared better in the statistics where he has the most control.
The biggest reason for his higher ERA this season is poor luck. The Marlins righthander has allowed a .337 batting average on balls in play. Without getting into the detailed explanation, this means that the Florida fielders have converted an extremely low percentage of batted balls into outs with Nolasco on the mound. He also has the NL’s lowest left on base percentage (63.3), another example of poor luck. As the season progresses, these trends should become less extreme and Nolasco’s ERA will therefore improve.
A pitcher's statistics get impacted by the quality of hitters they face as well. The batters who have hit against Nolasco owned a higher combined OPS (.746) than those faced by all but one other NL pitcher.
When you take an in-depth look at his numbers, Nolasco has improved from last season. Especially in time frames less than a full season, core numbers can prove misleading.
