In an effort to address roster gaps, the Arizona Diamondbacks made a series of transactions on Monday, May 12—moves that may have a notable impact on both their infield depth and bullpen reliability going forward.
The biggest move of the day was the long-awaited return of top prospect Jordan Lawlar, who was called up from Triple-A Reno after an impressive performance in the Pacific Coast League over the season’s first six weeks. His addition provides the D-backs with a crucial boost in athleticism and potential as they work to reconfigure their infield.
However, Lawlar wasn’t the only reinforcement added on Monday. The team also activated veteran right-handed reliever Kendall Graveman from the injured list, paving the way for his much-anticipated Diamondbacks debut after sitting out the entire 2024 season due to shoulder surgery.
To clear room on the 40-man roster, Arizona made two moves, designating infielder Garrett Hampson and left-handed reliever José Castillo for assignment. Both had been part of the team’s depth mix but were squeezed out following underwhelming performances early in the season.
Graveman’s return offers hope for Arizona’s struggling relief corps
Although Lawlar’s promotion is the headline move, Graveman’s return could quietly be just as significant for a Diamondbacks bullpen that has struggled mightily. Heading into Monday, Arizona’s relievers ranked 25th in ERA (4.95) and 29th in home runs allowed per nine innings (1.38 HR/9) — concerning numbers for a club aiming for a postseason run.
At 34 years old, Graveman is well-versed in handling high-leverage situations. He joined the Diamondbacks in February on a one-year, \$1.35 million contract that includes a \$5 million mutual option for 2026. Once a starter, he has transitioned into a dependable late-inning reliever, bringing with him nearly ten years of MLB experience and a solid history of success in multiple roles.
In 2023, he divided his time between the Chicago White Sox and Houston Astros, establishing himself as one of the more reliable relief pitchers in the American League.
- With the White Sox: 45 appearances, 3.48 ERA, 8 saves, 42 strikeouts over 44 innings.
- With the Astros: 23 appearances, 2.42 ERA, 24 strikeouts over 22.1 innings.
Combined, Graveman finished the year with a 3.12 ERA and 66 strikeouts over 66 1/3 innings, showcasing his ability to handle both setup and closing duties.
While the Diamondbacks are counting on Graveman to help steady their bullpen, it’s reasonable to keep expectations in check. Coming back after missing a full season due to shoulder surgery is a significant challenge, and he may need some time to return to peak performance.
That said, if Arizona can get even a near replica of Graveman’s 2023 performance, it would greatly help in tackling the bullpen’s issues with limiting home runs and closing out games effectively.
Arizona’s front office has made it clear they won’t remain inactive. By bringing in Lawlar and Graveman, the Diamondbacks are showing their determination to stay aggressive in chasing another playoff appearance. It will be intriguing to watch how these changes play out and whether additional reinforcements will be needed before the trade deadline.
