The Washington Nationals continue their road trip against the Arizona Diamondbacks on Sunday, June 1, 2025. Washington starts prospect Mitchell Parker, while Arizona sends ace Corbin Burnes to the hill. The DโBacks are heavy -200 favorites at home, with a total around 8.0 runs. Arizonaโs recently acquired ace looks to shut down the rebuilding Nats.
Pitching Matchup Analysis
Washingtonโs Mitchell Parker (1-1, 5.40 ERA) is a young left-hander making just his third big-league start. Heโs shown flashes of strikeout ability in the minors but also issues with control. In ~10 MLB innings so far, Parker has a 1.60 WHIP and has struggled with walks. Facing a mostly right-handed Arizona lineup in a hitterโs park will be a steep challenge. On the flip side, Corbin Burnes (4-2, 3.05 ERA) takes the mound for Arizona. Burnes, a former Cy Young winner in Milwaukee, has settled in as the DBacksโ ace after a mid-season trade. Heโs logged 88 strikeouts in 82.2 innings with a 1.10 WHIP. Burnesโ cutter and curve combination has been lethal; he also keeps the ball in the yard (under 1.0 HR/9). This is a lopsided pitching matchup: Burnes has a clear, decisive edge in experience and stuff over the inexperienced Parker. Barring the occasional home run susceptibility that sometimes bites Burnes, he should handle a Nationals lineup that ranks near the bottom of MLB in slugging. Look for Burnes to go 6-7 innings strong, while Parker may be chased early if his command falters.
Key Factors (Park, Weather, Umpire)
Chase Field in Arizona is somewhat hitter-friendly, especially with the roof open on a hot day. Forecast is 100ยฐF and sunny in Phoenix, but likely the roof will be closed for comfort. With the roof closed, conditions are neutral and wind is a non-factor. That helps Burnes further โ no environmental hurdles. If by chance the roof is open (unlikely at 100ยฐF), dry desert air can help the ball carry. Either way, Burnes has had success in all environments. Parker might have to contend with a lively infield; Chase Fieldโs turf can lead to fast grounders. One factor to consider: the DBacks are aggressive on the basepaths, and Parkerโs inexperience could be exploited (watch for Corbin Carroll stealing if he reaches). The umpire for this game is not noted, but if an experienced one with a normal zone is present, it should not hinder Burnes much โ heโs around the zone and can adjust. Washingtonโs bullpen is below average, so if Parker exits early, Arizona could feast late as well. The Diamondbacks also play good defense (top 5 in MLB in Defensive Runs Saved), which should back Burnes nicely. All signs point to Arizona controlling this game on the mound.
Team Trends (Last 5, Injuries)
The Nationals are 1-4 in their last 5 games, and the offense has been mostly quiet (shut out twice in that span). Joey Meneses remains one of the few threats in the lineup, but overall the Nats struggle to produce runs. On the road, theyโve especially had issues scoring more than 3 runs consistently. The Diamondbacks are 4-1 over their last five, riding strong pitching. However, their offense has been only average lately โ they scored just 3, 2, and 4 runs in wins this week. Facing softer pitching like Parker could get them back on track. Notably, Arizona has seen unders hit in 4 of their last 5 due to great pitching and modest hitting. Injury notes: Washingtonโs lineup is missing youthful spark CJ Abrams (on the IL with a knee sprain), further weakening their attack. Arizona is without Ketel Marte (day-to-day, quad tightness) and he might sit another game โ heโs a key switch-hitter for them. Even so, Arizonaโs depth (Emmanuel Rivera, Alek Thomas) has filled in adequately. In summary, Washington is trending downward, Arizona upward. The Nats often lose by multiple runs (their last 4 losses were by 2+ runs). The DBacks typically take care of business as big favorites behind their ace.
Our Pick & Bet Recommendation
Our Pick: Diamondbacks 5 โ Nationals 2. Itโs hard to see past the mismatch on the mound, so we like Arizona -1.5 (Run Line). With Burnes likely to dominate and the Nats offering little resistance offensively, the DBacks should win by at least a couple of runs. Laying -200 on the moneyline is steep, so run line at plus odds is the value play. We also lean Under 8.0 runs. Burnes might give up 1 or 2 at most, and Arizona would have to do the bulk of scoring to hit the over. Given Arizonaโs own recent modest scoring and potentially no Marte, five runs by them feels about right. That would still keep it under. The risk to the under is if the Natsโ bullpen implodes late or Parker gets shelled for a big inning; however, Washingtonโs lack of power makes a huge total from Arizona less likely. Burnes strikeout props could be enticing (maybe over 7.5 Ks) against a free-swinging Nats squad. But our best bet: Diamondbacks -1.5. They are 7-3 in Burnesโ starts since he joined, and many of those wins have been comfortable. Look for Arizona to back their ace with enough run support to cover the spread.
