On this episode of the SIS Baseball Podcast, senior research analyst Mark Simon (@MarkASimonSays) opens the show by praising the Cardinals infield’s defensive excellence (0:52) and is then joined by Arizona Diamondbacks Gold Glove-winning shortstop Nick Ahmed (@NickAhmed13).

Ahmed talks about the kinds of things he has improved upon from one year to the next (2:04), the challenge of turning double plays in shifts (3:15), what goes into making a diving play (6:20), changing positioning based on which pitcher is on the mound (7:25), the most underrated Diamondbacks defender (9:20), his impressions of defensive metrics (11:33) and advice he would give to those who want to play defense like him (13:12).

Mark is also joined by senior research analyst Alex Vigderman (@VigManOnCampus). They discuss some of Ahmed’s observations (15:07), salute Javier Baez as the top defender in August (17:25), run through a list of the Defensive Runs Saved leaders in the minor leagues (18:51) and talk about an unusual defensive alignment against Eric Hosmer (21:47). Alex also gives tips on job hunting in the baseball analytics world (23:51).

Lastly, the show closes with ridiculous numbers on Minor League Runs Saved leaders of the past (a predictive stat!) and low pitcher BABIP (29:09). Tune in!
