Starting Pitchers for Tuesday Night Contest
The White Sox are scheduled to start Anthony Kay, who enters with a 3-1 record, 4.61 ERA, and 1.54 WHIP over 41 innings. Kay has allowed 44 hits while striking out 29 batters and surrendering six home runs this season. Seattle has not yet announced a starting pitcher for this matchup. 
White Sox Bringing Offensive Momentum West
Chicago enters Tuesday with a 24-22 overall record and a 10-12 mark on the road. The White Sox have won four of their last five games and recently took two of three against the Cubs, including a 9-8 extra-inning victory and an 8-3 win. Chicago also picked up back-to-back victories over Kansas City earlier in the week, showing improved offensive production throughout the recent stretch.
The White Sox are batting .236 with 211 runs scored and 66 home runs this season. Chicago owns a .325 on-base percentage and .412 slugging percentage while collecting 357 hits overall. The pitching staff has posted a 4.35 ERA and 1.38 WHIP while holding opponents to a .242 batting average.
One major strength for Chicago has been power production. The White Sox have already hit 66 home runs this season, which is the highest total between these two teams entering the matchup. The recent offensive performances against the Cubs also suggest the lineup is beginning to generate more consistent scoring opportunities.
Mariners Looking to Respond at Home
Seattle enters this game with a 22-26 overall record and a 12-14 home mark. The Mariners have struggled recently, losing four of their last five games. Seattle was swept in three straight games by San Diego over the weekend after previously earning an 8-3 road win against Houston. The offense has been inconsistent during the recent stretch, including a shutout loss against San Diego.
The Mariners are batting .228 as a team with 198 runs scored and 54 home runs. Seattle owns a .319 on-base percentage and .376 slugging percentage while collecting 362 hits overall. On the mound, the Mariners have been more effective than Chicago with a 3.75 ERA and 1.23 WHIP despite opponents batting .252 against them.
Seattle’s biggest strength entering this matchup has been pitching consistency. The Mariners hold the better ERA and WHIP between these two teams, helping them stay competitive even when the offense has struggled. However, Seattle will need stronger offensive production after scoring only seven combined runs over the last three games.

Chicago White Sox vs Seattle Mariners Picks and Prediction
Chicago White Sox vs Seattle Mariners Pick
- Pick: Chicago White Sox Moneyline
Chicago enters this matchup playing the better baseball overall over the last week. The White Sox have won four of their last five games and have shown strong offensive production during that stretch, including 9-8 and 8-3 victories over the Cubs. Chicago also holds the advantage in runs scored, home runs, on-base percentage, and slugging percentage entering this game. While Seattle has stronger pitching numbers overall, the recent offensive momentum gives the White Sox value in this matchup.
Chicago White Sox vs Seattle Mariners Total Pick
- Pick: Over 8.5
I like the over because Chicago’s recent games have featured plenty of offense, including 9-8, 8-3, and 10-5 results. The White Sox have also hit 66 home runs this season and continue to generate power consistently. Anthony Kay enters with a 4.61 ERA and 1.54 WHIP, which could create opportunities for Seattle offensively as well. With Chicago swinging the bats well lately and both teams capable of producing home runs, this game feels favorable toward the over.
