The Washington Nationals visit the Arizona Diamondbacks at Chase Field in Phoenix on Saturday, June 6, 2026, with first pitch set for 4:10 p.m. ET on MLB.TV. Washington enters at 32-32 and third in the NL East, while Arizona is 33-30 and second in the NL West. This is Game 2 of the weekend series after the Nationals took Friday’s opener in loud fashion.
Washington comes in off a 14-1 win, and it was not cheap offense either. Luis García Jr. hit two homers with six RBIs, James Wood, CJ Abrams and Daylen Lile also went deep, and the Nationals pushed their season run total to a major-league-best 345. Arizona, meanwhile, has lost six of its last eight, so this is a bounce-back spot but not an automatic one.
The pitching matchup is Zack Littell against Eduardo Rodríguez. Littell brings some recent improvement, but the full-season profile still has red flags. Rodríguez has been one of Arizona’s most reliable starters, and that is why the Diamondbacks are favored even after getting run out of their own park Friday night.

Washington Nationals Betting Form
Washington’s offense is not some small-sample surprise anymore. The Nationals are scoring, they are getting on base, and they have enough left-handed thunder to make any right-handed-heavy staff uncomfortable. Abrams gives them speed and contact at the top, Wood gives them real middle-order damage, and García’s Friday eruption showed how deep this lineup can get when the lower half starts turning over. The Washington Nationals stats and results make it pretty clear that this team is far more dangerous offensively than its .500 record might suggest.
The concern is still run prevention. Washington has had trouble keeping games clean, especially with the long ball, and that is not a small issue at Chase Field even with the roof closed. Littell is 5-4 with a 5.01 ERA, 1.37 WHIP, 35 strikeouts, 19 walks and 15 homers allowed across 59.1 innings. That homer rate is the number that jumps out. Arizona has enough left-handed and switch-hitting pressure to punish mistakes if Littell misses middle.
There is a case for Washington as an underdog because the bats are hot and Littell has been steadier lately. He held San Diego to two runs over six innings in his last start and had a better May after a rough stretch. Still, betting Washington means trusting the offense to carry the ticket again, because the pitching edge is not on their side.
Arizona Diamondbacks Betting Form
Arizona has to respond after one of its uglier losses of the season. The Diamondbacks allowed five Washington homers Friday, got very little from their own offense outside of Aramis García’s solo shot, and had to burn through bullpen innings in a game that was over early. That makes the bounce-back angle tempting, but it also raises a fair question about bullpen freshness after a bad night.
The lineup still has enough upside to justify favorite pricing. Corbin Carroll enters as Arizona’s batting leader at .288 with a .375 OBP and .550 slugging percentage, while Ketel Marte has 11 homers and 37 RBIs. Geraldo Perdomo and Tommy Troy each had two hits Friday, which was one of the few positives in that loss. The Arizona Diamondbacks schedule and stats point to a team with enough offensive quality to get right quickly if Littell’s command slips.
Rodríguez is the main reason I still lean Arizona. He enters 5-1 with a 2.24 ERA, 1.19 WHIP, 52 strikeouts, 26 walks and only five homers allowed in 72.1 innings. The walk count is not perfect, but he has managed damage well, kept the ball in the yard, and gives Arizona a much more stable first-five profile than it had Friday.
Washington Nationals vs Arizona Diamondbacks Matchup Breakdown
This is a pretty clean starting pitching split. Washington has the hotter offense, but Arizona has the better starter. Rodríguez’s ability to limit home runs matters against a Nationals lineup that just hit five of them in the opener. Littell, on the other hand, has allowed 15 homers already, and Arizona’s top bats should get chances to lift the ball if he works behind in counts.
The bullpen angle is not as clean. Washington got five innings from Foster Griffin on Friday and protected its late arms because the game was out of reach. Arizona had to cover more uncomfortable relief innings, and Kade Strowd leaving with an injury adds another layer of uncertainty. That slightly trims the edge on a full-game Arizona moneyline, even if the starter matchup still favors the home side.
The roof is closed at Chase Field, so this is not a Phoenix heat handicap. That matters because bettors should treat the run environment as more controlled than a typical 102-degree outdoor setup. The ball can still carry in this park, but wind and extreme heat are not the main variables.
From a market standpoint, this is where an MLB betting guide mindset helps. Washington’s Friday result grabs attention, but the better question is whether the matchup repeats. I do not think it does. Rodríguez changes the shape of the game, and Arizona should have a better chance to control the first five innings.
Washington Nationals vs Arizona Diamondbacks Predictions and Best Bets
I lean Arizona on the moneyline. It is not a cheap number after a 14-1 loss, and I get why some bettors will want the plus money with Washington. The Nationals are swinging it well, they are the better current offense, and they already showed they can punish this staff. But Rodríguez gives the Diamondbacks the clearest edge in the game.
The run line is a little harder to trust. Arizona -1.5 at plus money is playable if you think Littell’s homer issues show up again, but after Friday’s bullpen usage, I would rather keep the bet simple. A 5-3 or 6-4 Diamondbacks win fits the handicap better than assuming they blow Washington out.
The total leans Over 9, but I do not love paying extra juice on it. Washington’s offense is red hot, Arizona’s lineup should bounce back, and Littell’s contact profile points toward traffic. The problem is Rodríguez. If he gives Arizona six quality innings, the Over needs Washington to do its damage late or Littell to unravel early. That is possible, just not my favorite angle at the current price.
For a derivative look, Arizona first five moneyline would be interesting if the price is reasonable. That isolates Rodríguez against Littell and reduces the bullpen uncertainty. From the listed main markets, though, Arizona moneyline is the cleaner bet.
Best Bet: Diamondbacks Moneyline -163.
