The numbers -- on both the offensive and defensive ends -- provide some substance to Matheny's bold claim. Entering Wednesday, no second baseman in baseball had a higher WAR (wins above replacement player) than Carpenter's 3.4 mark, as calculated by fangraphs.com.
On the offensive end, Carpenter ranks second among National League second basemen in batting average (.327), and first in on-base percentage (.411) and on-base plus slugging (.889). No leadoff hitter has a higher on-base percentage than Carpenter does from that spot.
His ultimate zone rating -- a defensive statistic that compares a player to an average defender at that position -- is 3.3, the third-highest in the NL.
