Conventional statistics don't reflect Duffy's defensive aptitude. He entered Tuesday ranked fifth among National League third basemen with a .965 fielding percentage. However, Duffy fares better based on modern metrics. Statistical composites on Fangraphs.com rank him second overall among NL third basemen behind Colorado's Nolan Arenado. Duffy also ranks third in the league in range factor per game, according to baseball-reference.com.
Duffy's probably no threat to unseat Arenado as the NL's Gold Glove winner at his position. But like his predecessor, Pablo Sandoval, he's defending well enough to gain attention.
• The aftermath of Kelby Tomlinson's first Major League hit was almost as memorable as the event itself.
