Seattle Mariners

Mariners (26-19) VS White Sox (14-33)

May 20 2025 | 7:40 p.m. ET | Guaranteed Rate Field, Chicago

Chicago White Sox
Moneyline Pick - Seattle Mariners (-178): B

Seattle comes into this matchup riding a four-game winning streak and appears well-positioned against a White Sox team that has dropped five in a row and is still dealing with several key injuries. Seattle’s starting pitching has an edge here, as their scheduled starter has consistently found success against Chicago in past meetings. Meanwhile, the White Sox have struggled to find consistency from their rotation and have had to lean heavily on a taxed bullpen lately, which only adds to the challenge.

With Seattle fielding a mostly healthy lineup and the White Sox dealing with a thin roster and recent bullpen fatigue, the odds justifiably favor the Mariners. The price may not offer overwhelming value, but given the current form and matchup trends, backing Seattle stands out as the right side, even if it doesn’t quite rise to a must-bet level.

Over/Under Pick - Under 8, (-110): B

Seattle’s recent winning streak owes a lot to the rotation, which has kept opposing lineups in check by allowing just six runs over the last five games. With a strong starting pitching matchup in place and the White Sox still trying to find answers at the plate during a five-game losing streak, both teams come in with some notable absences and lingering injuries. The matchup of quality starters, along with both bullpens performing well lately, points toward a tightly contested game with limited scoring.

Given the pitching trends and a park that tends to suppress runs, the under on eight looks appealing. The conditions and recent form from both clubs suggest that runs will be at a premium, making a low-scoring contest the most likely scenario for value-minded bettors.

Spread Pick - Seattle Mariners, -1.5 (-105): B

Seattle enters this matchup on a four-game winning streak, having outscored opponents by a wide margin, while the White Sox continue to struggle through a five-game losing streak and are still missing key contributors from their lineup. The pitching advantage also tilts toward Seattle, as their pitching staff as a whole has enjoyed past success against Chicago, while the White Sox will turn to a pitcher who has not fared well this season. Even with some minor injury concerns for Seattle, their lineup depth remains largely intact.

Given the recent form of both clubs and Seattle’s strong record in series openers, taking the Mariners to cover the run line looks like a confident and reasonable play. The matchup trends and current momentum make laying the 1.5 runs at near-even odds a smart value, earning this bet a solid B for confidence.
