The 2018 Diamondbacks' offense has essentially been stars-and-scrubs. Lineups often featured Nick Ahmed, Jeff Mathis, and Jarrod Dyson hitting in front of the pitcher. While all of these players have a clear purpose on the team, it places a massive pressure on the top of the lineup to produce runs consistently and often. It worked well enough in April; the offense was middle of the pack in terms of run production, which is fine when the pitching staff is one of the best in the league. But when May reared his ugly head, the flaws of the strategy became clear: it only works when the stars are healthy and performing. A combination of injury and ineffectiveness plagues the Diamondbacks' four offensive stars, and the offense was the worst in the league. Clearly, they weren't that bad, but something needed to change. Cue Jon Jay.
