MLB Data & Insights
Rising Stars Clash: Nationals vs D-backs in Phoenix Showdown
Baseball’s future is now—and it’s on full display in Phoenix this weekend.
The Arizona Diamondbacks host the Washington Nationals in a three-game set that features two of the National League’s most explosive young hitters: Corbin Carroll and James Wood. Carroll, 24, and Wood, 22, both rank in the NL’s top five for home runs, combining for 31 dingers this season.
Despite a recent slump (2-for-23), Carroll remains third in the league with 16 homers. Wood, meanwhile, is red-hot, blasting three homers in his last five games—including a jaw-dropping 448-footer earlier this week.
Pitching Matchup: Merrill Kelly vs. Jake Irvin
Friday’s opener will see Arizona righty Merrill Kelly (5-2, 3.52 ERA) face off against Washington’s Jake Irvin (4-1, 3.42). Kelly has dominated the Nationals in his career, going 3-0 with a 3.79 ERA in three starts. But Irvin’s record against Arizona? Less impressive: 0-2 with a 5.40 ERA across four games.
There’s a bit of personal history baked into this one too. Corbin Carroll is 4-for-9 with two homers off Irvin, while Ketel Marte—who might return from illness Friday—is also 4-for-9 with a home run.
Nationals Rolling, D-backs Reeling
Momentum clearly favors Washington right now. The Nats have won eight of their last 11, including a 9-3 extra-innings win over Seattle to cap a successful West Coast swing. James Wood isn’t the only one heating up—Josh Bell has homered in back-to-back wins, and Robert Hassell III, part of the Juan Soto trade, just hit his first career homer.
Hassell called the moment “a blessing” after notching his first three-hit game on Wednesday.
Arizona, on the other hand, is in a tailspin. They’ve dropped seven of eight games and were just outscored 19-1 over the last 13 innings against the Pirates. The bullpen’s been a big problem, with a 5.49 ERA—second-worst in the NL. Only Washington’s is higher at 6.08.
What’s At Stake
The Nationals took the first series between these teams in early April, winning two of three. This weekend, the D-backs are desperate to turn things around. Manager Torey Lovullo says the team needs to “be better—now,” showing visible frustration after a rough stretch that has Arizona two games under .500.
With playoff races heating up and young talent taking the spotlight, this series has all the makings of an early summer showdown you won’t want to miss.
