Starting Pitchers Open Important Series in Seattle
Chicago is expected to start Noah Schultz, who enters with a 2-2 record, 4.91 ERA, 1.36 WHIP, 29.1 innings pitched, 19 hits allowed, 26 strikeouts, 21 walks, and two home runs allowed. Seattle counters with Bryan Woo, who is 3-2 with a 3.91 ERA, 1.00 WHIP, 53.0 innings pitched, 43 hits allowed, 47 strikeouts, 10 walks, and six home runs allowed. Woo enters with the lower ERA and significantly stronger WHIP, while Schultz has struggled more with walks despite limiting home runs effectively. 
White Sox Entering Seattle With Momentum
Chicago comes into Monday night with a 24-22 overall record and a 10-12 mark on the road. The White Sox recently won over the Cubs 9-8 in 10 innings and also recently won over the Cubs 8-3. Before those victories, Chicago recently lost to the Cubs 10-5 but also recently won over Kansas City 6-2 and 6-5. The White Sox have won four of their last five games entering this road series.
The White Sox are batting .234 with 202 runs, 345 hits, 64 home runs, a .324 on-base percentage, and a .409 slugging percentage. On the mound, Chicago owns a 4.32 ERA with a 1.37 WHIP, 183 walks, 360 strikeouts, and a .242 opponent batting average.
Chicago’s biggest strength entering this matchup is power production. The White Sox lead this matchup with 64 home runs and have consistently generated offense recently, scoring at least six runs in four of their last five games. The concern remains overall pitching efficiency and walk totals.
Mariners Looking to Defend Home Field
Seattle enters this matchup with a 22-25 overall record and a 12-13 home record. The Mariners recently lost to San Diego 7-4 and also recently lost to the Padres 2-0. Before those defeats, Seattle recently won over Houston 8-3 and 10-2 while recently lost to Houston 4-3 in 10 innings. Seattle has alternated strong offensive performances with quieter games over the last week.
The Mariners are batting .232 with 195 runs, 361 hits, 54 home runs, a .321 on-base percentage, and a .382 slugging percentage. Seattle’s pitching staff owns a strong 3.66 ERA with a 1.23 WHIP, 118 walks, 397 strikeouts, and a .252 opponent batting average.
Seattle’s biggest strength is pitching consistency. The Mariners carry the lower ERA and WHIP while also issuing far fewer walks than Chicago. That control advantage has helped Seattle stay competitive despite a losing record entering the series.

Chicago White Sox vs Seattle Mariners Picks and Prediction
Chicago White Sox vs Seattle Mariners Pick
- Pick: Seattle Mariners Moneyline
Seattle gets the edge because of the stronger pitching profile and the better starting pitching matchup entering Monday night. The Mariners have the lower ERA, lower WHIP, and significantly fewer walks allowed compared to Chicago. Bryan Woo also enters with a 1.00 WHIP and stronger overall numbers than Schultz. Chicago has played well recently, but Seattle’s pitching consistency at home gives the Mariners the advantage in this matchup.
Chicago White Sox vs Seattle Mariners Total Pick
- Pick: Over 7
I lean toward the over because Chicago’s offense has been producing consistently during its recent winning stretch. The White Sox have scored at least six runs in four of their last five games and enter with 64 home runs on the season. Seattle has also shown the ability to score in bunches, including recent games with eight and ten runs against Houston. Even with Seattle’s strong pitching numbers overall, this total feels slightly low considering the recent offensive trends.
Final Score Prediction: Seattle Mariners 5 – Chicago White Sox 4
