2025 Arizona Diamondbacks Predictions with World Series Odds and Season Win Total Picks

by Ryan Cobbett - 3/18/2025

Arizona Diamondbacks predictions Corbin Burnes

Last season was disappointing, as the Diamondbacks went from MLB’s runners up to missing out on the playoffs with a 89-73 record. Unfortunately for Arizona, their five-game improvement on the win total from 2023 to last season wasn’t enough to propel them into the playoff picture. Arizona finished nine games behind the first-place Los Angeles Dodgers and missed out on the wild card spots thanks to the New York Mets and Atlanta Braves both holding the tiebreaker against the Diamondbacks.

Despite playing in only 136 games, Ketel Marte led the Diamonbacks with a 6.8 WAR. He clubbed a team-best 36 homeruns while recording 95 RBIs and a .932 OPS. Corbin Carroll and Geraldo Perdomo were tied for second on the team with a 3.4 WAR. Carroll led the team with 35 stolen bases while also hitting 22 homeruns and tallying 74 RBIs. Eugenio Suarez had an incredible year, as he was the only other Arizona player to reach the 30-homerun mark while he led the team with 101 RBIs. Christian Walker hit 26 homeruns and finished the season with 95 RBIs, while Joc Pederson marked the fifth player for Arizona to reach more than 20 homeruns. As a team, they ranked first in the MLB in runs, fifth in homeruns, and second in OPS.

The pitching staff wasn’t the best for Arizona, as the team finished 27th in ERA (4.62) and 27th in WHIP (1.35). Brandon Pfaadt led the team with 181.2 innings pitched, but he finished with a 4.71 ERA and a lowly 0.5 WAR. Zac Gallen led the pitchers with a 2.7 WAR after going 14-6 and posting a 3.65 ERA across 148 innings. Ryne Nelson was a reliable pitcher, as he recorded 12 quality starts across 25 starts and he finished the season with a 1.7 WAR. Reliever Justin Martinez was the breakout pitcher of the year for Arizona, as he recorded a 2.0 WAR after finishing with a 2.48 ERA, eight saves, and a 11.3 K/9 ratio across 72.2 innings of work.

Arizona Diamondbacks Key Additions/Losses

At the end of the season, Walker, Josh Bell, Kevin Newman, and Paul Sewald all became free agents, while Arizona also saw Pederson decline his player option. They would then non-tender reliever Brandon Hughes and traded Slade Cecconi to the Cleveland Guardians.

The Diamondbacks replaced Walker by acquiring Joshy Naylor from the Guardians as the return in the Cecconi deal. They followed that up by adding Corbin Burnes to a rotation that really struggled last season. Arizona also focused on deepening their bullpen by signing Kendall Graveman to a major league deal while also taking fliers on relievers John Curtiss, Scott McGough, Jeff Brigham, Shelby Miller, Jose Castillo, and Josh Winder. They added depth by bringing in Christian Pache, Garrett Hampson, Ildemaro Vargas, and Trey Mancini.

Arizona Diamondbacks Prospect Outlook

The Arizona farm system is not in good shape. They have just one prospect listed in the MLB’s Top 100 Prospects list and have the 25th ranked farm system in the league. Shortstop Jordan Lawlar is the only prospect that made the list for Arizona, and the 22-year-old should make the MLB roster. He has plus speed and an elite glove that could earn him some playing time this season.

Arizona Diamondbacks X-Factors

The Starting Rotation- The rotation is going to be what can take this team back to the postseason. Their lineup is one of the best in the National League, but the rotation needs to drastically improve. Burnes and Gallen form one of the best 1-2 punches in the MLB. While you could do a lot worse than having Merrill Kelly, Eduardo Rodriguez, and Pfaadt, if Jordan Montgomery can erase his awful season from memory and return to form, their rotation could end up being one of the best in the MLB. It also helps to have Nelson, who was their second most reliable option last season, as a depth piece.

Front Office- With a weaker farm system, the potential for a big deadline deal is slim. The Diamondbacks should find themselves back in the playoff picture this season with the improvements to their rotation, but they will likely be in the market for a closer or another bat to boost their lineup after losing the pop with the departures of Pederson and Walker. Lawlar might be on the table for a player with years left on his contract, but don’t expect Arizona to part with their top prospect.

Arizona Diamondbacks Expectations

Arizona will rival the San Diego Padres and the two non-division winning NL East teams for the final wild card spot. The rotation should perform much better than last season, and their lineup will continue to produce. Though there is no catching the Dodgers in the division standings, they should be in the mix for a wild card. And then with Burnes and Gallen leading the rotation, they will have the pieces in place to take on anyone in a playoff series.

Arizona Diamondbacks Notable Odds:

Win Total: 86.5

World Series Champions- +3000

Pennant Winners- +1500

Division Winners- +1000

NL MVP- Ketel Marte +3300

NL MVP- Corbin Carroll +4500

NL Cy Young- Corbin Burnes +1600

NL Cy Young- Zac Gallen +2500

NL Cy Young- Brandon Pfaadt +9000

NL Rookie of the Year- Jordan Lawler +1100

2025 Arizona Diamondbacks Predictions

Burnes at +1600 to win the NL Cy Young is a great value pick. Though the NL is much deeper with elite pitching than the AL, Burnes remains one of the best and most consistent pitchers in the MLB as a whole and he could find himself in the mix again for the NL’s winner. Carroll has 30/30 potential and could potentially be in the mix for the MVP, but it’s not worth the juiced odds as Carroll’s numbers weren’t impressive last season. As for the team’s futures, the win total should only improve. With the projected mark set at 86.5, I am all about the over on the win total as these Diamondbacks should reach the 90-win mark. At +1500 to win the NL, and a duo like Burnes and Gallen in the rotation, they may be an entertaining dark horse team to follow, but I don’t think they are on the same level as the two NL East teams who will not win the division.
