ARIZONA DIAMONDBACKS

The Diamondbacks went from a 2023 World Series appearance to missing the playoffs in both 2024 and 2025, creating a turbulent market for their top cards. After going 89-73 in 2024 and slipping to 80-82 in 2025, the team dealt veterans Josh Naylor and Merrill Kelly at the 2025 trade deadline while losing ace Zac Gallen to free agency. Corbin Carroll won the 2023 NL Rookie of the Year and made All-Star teams in 2023 and 2025, keeping his cards relevant despite the team's downturn, while Gabriel Moreno emerged as a cornerstone after his December 2022 trade from Toronto, winning a 2023 Gold Glove and leading MLB catchers in defensive runs saved.

Where they stand: The Diamondbacks are 60-53 and sitting second in the NL West as of August 9, 2026, positioning themselves as a Wild Card contender. The offseason addition of third baseman Nolan Arenado in a trade with St. Louis brought a veteran presence, though he struggled in 2025 with just 12 homers and a .666 OPS. The team re-signed Zac Gallen to a one-year, $22.05 million deal, but he's on the injured list with elbow inflammation and a 6.34 ERA, while the rotation has battled injuries to Corbin Burnes, Ryne Nelson, and Michael Soroka.
