A few weeks ago we talked about how Andrelton Simmons is having the best defensive season since we started tracking advanced defensive metrics in 2003. It turns out that he has some company this year. Three other players are having historic-level defensive seasons as well—Gerardo Parra, Carlos Gomez and Manny Machado. With one week left in the season, all four of these players are on track to break Brett Gardner's Defensive Runs Saved mark of 35 runs set in 2010. Here is where they stand this year in saving runs defensively for their teams:
| Most Defensive Runs Saved, 2013
| Andrelton Simmons, Braves
| Gerardo Parra, Diamondbacks
|| LF, CF, RF
| Carlos Gomez, Brewers
| Manny Machado, Orioles
Like Brett Gardner in 2010, Gerardo Parra is saving runs at multiple positions. He has saved 35 runs in right field, four in center and one more playing left field. He could even overtake Simmons in the final week of the season. With all the attention Simmons has been getting for his defense, wouldn't that be something?
