Starting Pitchers for Arizona and Washington

Arizona is scheduled to start Kohl Drake, who has made five innings of work and enters with a 0-0 record, a 1.80 ERA, and a 1.20 WHIP. The left-hander has allowed four hits and no home runs while recording five strikeouts and issuing two walks. Washington is expected to counter with Miles Mikolas. The right-hander is 3-7 with a 5.60 ERA and a 1.34 WHIP across 98 innings, allowing 111 hits and 21 home runs while collecting 51 strikeouts and issuing 20 walks.

Arizona Carries a Four-Game Winning Streak Into Washington

The Diamondbacks enter Sunday with a 55-49 overall record, although they are three games below .500 on the road at 24-27. Arizona recently defeated Washington 3-2 after earning wins of 10-6 over St. Louis, 15-5 over the Athletics, and 6-5 in 10 innings over the Athletics. Its only defeat across the last five games was a 5-2 loss to the Athletics. The Diamondbacks have therefore won four consecutive games and four of their last five.

Arizona is batting .242 with 469 runs, 839 hits, and 101 home runs. The Diamondbacks own a .313 on-base percentage and a .394 slugging percentage. Their pitching staff has produced a 4.20 ERA and a 1.29 WHIP with 300 walks and 704 strikeouts. Opponents are batting .252 against Arizona, which holds a 22-18 record in day games.

The Diamondbacks’ primary strength entering this matchup is their recent form. Arizona has scored at least six runs in three of its last five contests and has found a way to win four straight games, including Friday’s series matchup at Nationals Park. The club also holds a lower team ERA and WHIP than Washington. However, Arizona’s 24-27 road record shows that its overall success has not been as consistent away from home.

Washington’s Offensive Production Creates a Home Threat

The Nationals enter the matchup with an even 52-52 overall record but a 20-32 record at Nationals Park. Washington recently lost 3-2 to Arizona after completing a road stretch with three wins in four games. The Nationals recently defeated Colorado 8-0 and 7-3 while also recording a 5-2 win over the Athletics. Their other recent result was an 8-7 loss to Colorado, giving Washington three victories and two defeats across its last five games.

Washington is batting .253 with 569 runs, 905 hits, and 151 home runs. The Nationals have recorded a .327 on-base percentage and a .442 slugging percentage. Their pitching staff carries a 4.77 ERA and a 1.40 WHIP with 367 walks and 823 strikeouts. Opposing hitters have produced a .260 batting average against Washington, which is 23-24 during day games.

The Nationals’ clearest advantage is their offensive statistical profile. Washington has scored 100 more runs than Arizona while producing 66 more hits and 50 more home runs. The Nationals also hold the higher batting average, on-base percentage, and slugging percentage. The concern within the supplied numbers is the pitching performance, as Washington trails Arizona in team ERA, WHIP, and opponent batting average. Its scheduled starter also enters with a 5.60 ERA after allowing 111 hits and 21 home runs in 98 innings.

Arizona Diamondbacks vs Washington Nationals Picks and Prediction

Arizona Diamondbacks vs Washington Nationals Pick

• Pick: Arizona Diamondbacks Moneyline

Arizona is my selection based on its stronger overall record, four-game winning streak, and more favorable pitching numbers. The Diamondbacks have already earned a 3-2 road victory over Washington in the recent information provided and have won four of their last five games. Washington owns the higher matchup predictor percentage at 52.1 percent and has the stronger offensive totals, but its 20-32 home record is difficult to overlook. Arizona also holds advantages in team ERA and WHIP, while the scheduled pitching comparison favors the Diamondbacks based on the supplied statistics.

Arizona Diamondbacks vs Washington Nationals Total Pick

• Pick: Over

Take the over if the total is set at 9.0. I am leaning toward the over because Washington has scored 569 runs with 151 home runs and a .442 slugging percentage, while its pitching staff has a 4.77 ERA and a 1.40 WHIP. Arizona has scored at least six runs in three of its last five games, including totals of 10 and 15 runs in two victories. Washington has also recently participated in games with final combined totals of 15, 10, and 7 runs. Although the first recent meeting ended 3-2, the broader offensive and pitching statistics point me toward the over at the suggested number.
