Arizona Diamondbacks vs. Washington Nationals Odds, Line, Picks, and Prediction - July 22 | 2022 MLB Season

The Arizona Diamondbacks will host the Washington Nationals Friday night. The Diamondbacks beat the San Diego Padres 3-1 last Sunday to improve their overall record to 40-52 on the season. Meanwhile, the Nationals now find themselves at 31-63 on the year after their 7-3 win over the Atlanta Braves on Sunday.

Washington has been a bad team away from home, carrying just a 16-27 away record this season. They now trail by a whopping 27.5 games in the National League East division.

Zac Gallen, who is 4-2 with a 3.65 ERA, will start Friday for Arizona. He has been solid this year, and he'll pitch against a below-average Nationals lineup. In his previous start, Gallen went 6 2/3 innings, allowing four hits and two earned runs while striking out five. Look for him to have another solid outing on Friday night against a team that is near the bottom in runs per game.

Patrick Corbin, who is 4-12 with a 5.87 ERA, will be on the hill Friday for Washington. The Diamondbacks' offense he'll face ranks #22 in runs per game, and in their past seven, they've averaged a paltry 2.6 runs per contest.

"2x All-Star. #AllStarGame // #NATITUDE" - Nationals

Corbin got lit up in his last start versus the Braves, allowing five earned runs in only five innings. Hen has had a handful of dominant starts as well as some starts where he's been rocked, so don't rely on the lefty for consistency.
