After years of being competitive, the Diamondbacks have looked to sell off some of their stars. Paul Goldschmidt is now in St. Louis, and they got Luke Weaver in return. Arizona has not made any moves to replace the 30+ HR hitter, and it looks like they won’t. This is going to leave a big power bat out of the lineup, which is desperately needed around a lot of good on-base hitters. While Goldschmidt was on the decline in terms of age, power, and speed, the absence of him in the lineup will be felt this season. They will likely try and fill in with Jake Lamb and Steven Souza for power. Souza is a low average option, and Lamb will need to stay healthy. As for Patrick Corbin, they were not going to resign him for big money, and while Arizona’s rotation is still strong, they will miss Corbin. There have been rumors of trading Zack Greinke as well, which could be a move before the deadline. They did replace Corbin’s place with Weaver, and his production as far as strikeouts won’t be the same, but a middle rotation guy who can eat some innings isn’t the worst move. If Robbie Ray and Zack Godley can bounce back into form, they are have a good one-through-three in the rotation.
Manager, Torey Lovullo, has made the decision to use Archie Bradley as the close in 2019. Whether this holds throughout the year, they will at least start him out that way. After a 1.73 ERA season, Bradley came back with a 3.64 ERA and struggled in the second half. Before the all-star break he had allowed a .243 wOBA to hitters, and in the second half allowed a .366 wOBA. His HR/9 went up, and groundball rate dropped over 10%. This is a bit concerning for a guy who had a 4.69 FIP in high leverage spots. If Bradley can rebound to his early form and 2017 form, he will have a successful career as a closer. Bradley was once a starter, and also a setup man. He will now try and be the rock at the back end of the bullpen.
Jake Lamb is going to move over to first base this year, and Eduardo Escobar will handle the third base role. Lamb played just 56 games last season, and you can tell even when healthy that he wasn’t right. He hit just .222, which was a career low, and his hard-contact suffered as well. If Lamb is going to miss more time, they will lack power in the middle of the order. In the 2016 and 2017 seasons, Lamb hit 29 and 0 HR, and had over 90 RBI. He was a prime bat from the left side of the plate, which is something Arizona will need this season.
