Winners of seven of their last nine games, the Orioles have found a much-needed spark at the perfect time as they continue to push their way into the playoff picture. However, it doesn’t get any easier from here as they prepare to face a Red Sox team that is equally motivated to string together wins and strengthen its position in the AL Wild Card race.

One thing we like about the Orioles here though is how they’ve been able to create offense without relying solely on the long ball while their pitching has done a better job of working ahead in counts and limiting quality contact. First baseman Pete Alonso has been particularly effective at converting pitches in the attack zone into high-quality contact with his offensive profile driven by elite exit-velocity generation and a pronounced pull-side damage tendency.

Taking all things into account, we like Alonso to record at least 2+ hits here and lead the Orioles into a nip-and-tuck win against the Red Sox. While the Red Sox remain one of the best teams in the league as far as batting average and pitching are concerned, we like to think that tired legs could become an issue for them here given that this is the team’s sixth game in as many days.
