The Colorado Rockies are mired in a five-game losing streak, and they’ve dropped seven of their last 10 contests overall. It has been a difficult stretch of baseball for a club trying to define its identity under the front office’s new regime, but they get a chance to stop the bleeding this afternoon. First pitch from Nationals Park is set for 4:45 p.m. MT..

Fortunately for Colorado, they are running into an opponent dealing with the same challenges. The Nationals are struggling heavily, managing just one win in their last five games while dropping eight of their last 10. Following a post-deadline sell-off that stripped the clubhouse of key talent and leadership, Washington’s lineup has resembled a husk of the squad that competed early in the year. Over their last 20 games, they have secured just six wins, putting their trajectory right in line with the Rockies.

To compete today, the Rockies need to capitalize on Washington’s organizational slump by generating steady offense, Colorado has a realistic path to finding value and stealing a win on the road.

The Breakdown

This afternoon’s pitching matchup features Colorado’s Ryan Feltner squaring off against Washington’s Cade Cavalli.

Cavalli has been the lone bright spot for a depressing Nationals roster, putting together a excellent run over his last 10 starts. Across his last 59.1 innings on the mound, he is fanning 11.07 batters per nine innings with a stellar 0.93 WHIP. That strikeout surge has translated to a 2.12 ERA during this stretch, making him a formidable hurdle for a Rockies lineup trying to find its footing.

Feltner, on the other hand, is trying to pull himself out of a prolonged rut. Over his last 10 starts (51.0 innings), the right-hander has dealt with constant traffic on the basepaths, issuing 4.06 walks per nine. Feltner has experimented with his pitch mix, but a lack of command has ballooned his WHIP to 1.73 and his ERA to 6.71 in that span. He has averaged just 5.10 innings per start recently, putting extra strain on the bullpen.

The defining X-factor in this matchup is whether Washington’s depleted offense can actually capitalize on Feltner’s command issues. Over their last 10 games, the Nationals have deployed one of the least productive offenses in baseball, averaging a meager 2.70 runs per game with an anemic .191 team batting average. Despite their own losing streak, the Rockies have managed to produce a respectable 4.60 runs per game over their last 10 outings.

For Colorado to take this one today, Feltner must use Washington’s offensive slump as a get-right opportunity. He needs to attack the strike zone, limit the free passes, and push deeper into the game. Offensively, the Rockies face a tall task against a red-hot Cavalli. They will need to grind out at-bats, avoid chasing his high-danger put-away pitches, and scratch across enough early runs to give Feltner a lead to work with.

Odds & Lines

Our Pick

Both of these teams are mired in prolonged slumps, making it tough to trust either side to lay some juice and win outright. While Cade Cavalli’s current dominance makes the Nationals a justifiable favorite today, betting heavy on a Washington squad that has dropped eight of its last 10 games is bad business.

Instead, look toward the total. Washington’s lineup has been lifeless lately. Despite Ryan Feltner’s recent struggles, he has a prime opportunity to limit damage against an opponent generating almost zero run support. On the other side, Colorado’s hitters have a brutal assignment against Cavalli, who has been suppressing traffic brilliantly. Even with both the Rockies’ and Nationals’ bullpens sporting identical, uninspiring 4.81 ERAs for the season, we are expecting a low-scoring, grind-it-out affair this afternoon.

Caesars is offering the Under 8 at -105, providing solid value in a matchup featuring two ice-cold rosters. If you are looking to place a wager, grab a Caesars promo to take advantage of their new user offers, or shop around for a BetMGM promo code to find the best line.

Pick: Under 8 (-105)

Player Prop Pick

While the Nationals’ lineup has struggled to make contact recently, Ryan Feltner’s inability to miss bats makes his strikeout prop a highly appealing target to fade this afternoon.

Feltner has fought his command and his put-away pitches, posting a meager 5.47 strikeouts per nine innings over his last 10 starts (51.0 innings). Instead of racking up punchouts, he has navigated heavy traffic, issuing 4.06 walks per nine in that same span.

This extended rut creates a highly profitable betting trend. Feltner has failed to exceed 3.5 strikeouts in six of his last seven outings, averaging exactly 2.86 punchouts per appearance during this stretch. Even against a slumping Washington lineup, his pitch counts are likely to climb early due to walks, preventing him from pitching deep enough into the game to register four strikeouts.

DraftKings is offering plus-money at +115 on the under, which presents excellent value on a pitcher struggling to find the strike zone.

Pick: Ryan Feltner Under 3.5 Strikeouts (+115)
