The wondrous Andrelton Simmons led all fielders with 41 Defensive Runs Saved last season, the defensive metric that Baseball Info Solutions measures by tracking every batted ball.
How good of a season was it? Here are the top 10 DRS totals over the past 10 seasons:
1. Andrelton Simmons, 2013: +41
2. Carlos Gomez, 2013: +38
3. Gerardo Parra, 2013: +36
4. Manny Machado, 2013: +35
5. Adam Everett, 2006: +34
6. Franklin Gutierrez, 2009: +32
(tie) Jack Wilson, 2007: +32
8. Troy Tulowitzki, 2007: +31
(tie) Albert Pujols, 2007: +31
10. Six players with +30.
So Simmons had an amazing year on defense. Was it a career year? Can he actually find a way to get better? Will the changing makeup of the pitching staff affect his DRS total? (More opportunities to make a play means more opportunities to help your DRS.)
Defensive numbers can certainly vary from year to year and it seems a little unreasonable to expect 41 DRS again from Simmons. Let's put the over/under at 31.5 Defensive Runs Saved.
