The Guardians are the only team that strikes out less. However, Stroman consistently throws 6+ strikeouts a game, including in his outing against the Nationals. His line is curiously placed at 4.5, so bettors should take advantage.Marcus Stroman Over 4.5 Ks (-122)Chicago Cubs vs. Washington Nationals PredictionAs previously stated, this game doesn't hold much importance in the 2022 MLB season, but these are still professional athletes playing for a paycheck. Josiah Gray's last start was against the Cubs, and he carved them up. When he's pitching well, he's unhittable. Bettors should expect more of the same in this one.Washington (+120)
