Perhaps the Diamondbacks’ second biggest need is to improve at shortstop. Their negative 1.3 Wins Above Average (WAA) ranked 26th in the Majors. Last season, Geraldo Perdomo was the primary shortstop (81% of shortstop PAs) due to injuries to Nick Ahmed (9% of shortstop PAs). Sergio Alcantara had 8% of shortstop PAs.
The good news for future seasons is that the Diamondbacks have two promising shortstops in the minors - Blaze Alexander, and top-100 prospect Jordan Lawlar. However, at the start of the season they may not be ready.
Presumably, Nick Ahmed will start next season as the primary shortstop because of his $10.
