San Francisco Giants vs Washington Nationals Prediction, Odds and Picks for Today, 04/18/26

The matchup sets up with two vulnerable starters in Adrian Houser for San Francisco against Cade Cavalli for Washington. Houser enters 0-2 with a 5.06 ERA and 1.56 WHIP, while Cavalli checks in at 0-1 with a 4.60 ERA and 1.72 WHIP, plus 12 walks in 15.2 innings. That is a lot of traffic on the bases from both sides before we even get to the bullpens.

The bigger driver is Washington’s offense. Entering the series, the Nationals are an elite run producer, while also showing proficiency in batting average, on-base percentage, slugging, and home runs. Houser is vulnerable in this spot against a team that can optimize scoring off a lot of runners put on. On the flip-side, Cade Cavalli has struggled with command which means the Giants may actually be able to generate some offense here contrary to their anemic profile. Put this all together and the over at 9 runs is reachable because Washington can do heavy lifting, and both starters have enough command and contact issues to let this game open up. I am happy to lay a little more juice on ths occasion in a set-up that is conducive for this total to clear this number comfortably. Back the Over.

Giants vs Nationals prediction: Over 9.0 Runs (-115) available at time of publishing. Playable to the number.
