Ryne Nelson is transitioning back to the starting rotation for the Arizona Diamondbacks, filling in for Corbin Burnes, who is facing an elbow injury. Nelson's flexibility has been notable as he has shifted roles multiple times this season.

His performances have significantly improved, boasting a 3.18 ERA since July 2, 2024. Manager Torey Lovullo credits Nelson's success to his improved pitch sequencing and the effectiveness of his cutter and breaking ball. Additionally, Nelson has adopted a more focused mental approach on the mound, avoiding the pitfalls of dwelling on past outings.

The Diamondbacks will rely on Nelson and the veteran pitchers, Zac Gallen and Eduardo Rodriguez, to maintain competitive standings while Burnes is sidelined. Gallen has recently found some form, while Rodriguez is expected to return soon, providing crucial depth for the team.

The Arizona Diamondbacks are gearing up for a home series against the Pittsburgh Pirates. Tonight's matchup features Diamondbacks RHP Ryne Nelson, who has shown promise in his recent starts, against Pirates LHP Andrew Heaney, who boasts a solid ERA of 2.91 this season. Nelson's last outing saw him limit the Dodgers to just one run in five innings, while Heaney has consistently kept opponents at bay, allowing more than two runs only twice this season. The Pirates have struggled offensively, ranking low in runs scored, despite the emergence of rookie sensation Paul Skenes, who has a remarkable 2.36 ERA and 70 strikeouts. The Diamondbacks have a favorable pitching lineup this week, with Corbin Burnes and Zac Gallen also set to pitch later in the series.

The New York Mets, with a record of 22-13, are heading to Phoenix to face the Arizona Diamondbacks (18-16) after a tough double-header loss against St. Louis. Griffin Canning will take the mound for the Mets, boasting a strong 4-1 record and a 2.61 ERA, while Ryne Nelson, who has a 1-0 record, will represent the D-backs. Arizona recently secured a thrilling win against Philadelphia, adding momentum to their upcoming matchup.

The latest odds show the Mets slightly favored at -115 on the moneyline, with a spread of -1.5. Despite the Mets’ recent performance against winning teams, they face a unique challenge coming off two losses and adjusting to road travel. An expert from Rotoworld suggests leaning towards the Diamondbacks, given their better overall record when Nelson doesn’t pitch. The Mets, however, have shown resilience, winning five straight with Canning on the hill.

Jordan Montgomery is regaining his confidence after a shaky start to the spring, showcasing marked improvement during a recent simulated game. His fastball velocity hovered between 89-91 mph, and he recorded two strikeouts while limiting hard contact against seasoned hitters. This performance is a significant step up from his last outing, where he allowed five runs in just one-third of an inning. Montgomery's pitching coach noted his evolving rhythm and focus, which may enhance his effectiveness as he competes for a rotation spot with the Arizona Diamondbacks.

With a $22.5 million player option exercised, Montgomery's performance is critical for the Diamondbacks, especially after a disappointing season that saw him finish with a 6.23 ERA. He is vying for a place in the rotation alongside Brandon Pfaadt and Ryne Nelson, both of whom have shown more consistent results recently. Montgomery's ability to incorporate feedback from teammates and adjust his approach will be crucial as the season approaches.

The National League West remains a battleground as teams vie for roster spots ahead of the season. The Arizona Diamondbacks are focusing on center field, with Jake McCarthy edging out Alek Thomas based on their early performances. While McCarthy's speed has proven valuable, Thomas has yet to deliver consistent power. The fifth starter role sees Brandon Pfaadt and Ryne Nelson in contention, while Justin Martinez and A.J. Puk compete to become the closer after Paul Sewald's departure.

Meanwhile, the Colorado Rockies are evaluating their right field options, with Hunter Goodman, Jordan Beck, and Zac Veen in the mix. Goodman’s dual role at catcher complicates things, and veterans may fill the gap if the youngsters don’t impress. Chase Dollander, the promising rookie, is expected to start in the minors due to spring struggles, while Seth Halvorsen appears to be the most viable closing option despite a historically tough environment for Rockies relievers. The Los Angeles Dodgers focus on second base and center field, with Tommy Edman likely starting regularly as the team assesses Hyeseong Kim's power revamp. Dustin May has secured the fifth starter role, but injury concerns loom for Tony Gonsolin.
