MLB Best Bets, Predictions & Expert Picks Tuesday, August 18, 2026

Analys

Kevin Gausman is the big name here, but he has not been pitching like an ace lately. His season ERA of four point three eight is mediocre, and his recent form of five point sixty five is even worse. He is facing a White Sox lineup that ranks seventh in the majors for scoring, so he is going to have his hands full. The Cubs do have the second best offense in baseball, but the White Sox defense is respectable at eighteenth. When you look at the head to head history this season, these teams have split four games right down the middle. The average margin in those games was only zero point three runs. The model thinks this game should be priced as a pick em with a spread of only zero point two. Getting the White Sox with a run and a half cushion is a massive edge. Chicago's south side team covers the spread in fifty six percent of their road games, which is much better than the Cubs at home. The White Sox score four point eight runs per game and allow four point one. And the White Sox are playing well right now with a three game winning streak. The Cubs only cover forty six percent of the time at Wrigley, making them a risky bet as favorites. Trust the numbers that say this game stays close or the Sox win outright.

The public sees Gausman on the mound and assumes the Cubs will cruise at home. They are ignoring his recent struggles and the fact that the White Sox have played them evenly all year.

Analys

This game features two of the better starters on the slate. Zac Thornton has been fantastic for the Mets with a two point sixty ERA. Even his recent starts have been strong, staying under three. Robbie Ray is pitching well for San Diego too, but the Mets have found a way to beat the Padres three times in four tries this season. The average margin of victory for the Mets in those games was two point three runs. The model likes the Mets to win this game fifty four percent of the time. When the books are giving you a run and a half with a team the model thinks should be favored, you take it every time. Both offenses are ranked in the bottom third of the league, so do not expect a lot of fireworks. This should be a pitcher's duel where one or two runs decide it. The Padres have a good road cover rate, but Thornton is the difference maker here. He has been more consistent than Ray lately. The Mets defense is also capable of backing him up in a tight spot. New York scores four point two runs per game and allows only three point three. Take the runs and run.

Bettors are looking at the Padres superior record and laying the runs. They are missing the fact that Thornton is the best pitcher in this matchup and the Mets have dominated the season series.

The pitching matchup in Pittsburgh is what drives this pick. Braxton Ashcraft has been struggling mightily for the Pirates, posting a five point forty six ERA over his most recent starts. That is a huge jump from his season average. Detroit counters with Keider Montero, who has been much more reliable with a three point twenty two ERA. The Tigers also have a significant advantage on the defensive side, ranking fifth in the league. Pittsburgh has a high powered offense, but the Tigers have the tools to keep them in check. Detroit won the only meeting between these two teams earlier this year by three runs. The model sees this as an even matchup and sets the spread at zero. That gives us a huge eighteen percent edge on the Tigers at plus one point five. Detroit is five and five in their last ten games and they have shown they can compete with anyone when their pitching holds up. And the Pirates have been mediocre lately, winning only four of their last ten. Detroit covers the spread in over half of their road games, and they should keep this one within a run or win it outright.

Casual fans see the high scoring Pirates offense and think they will blow out a Detroit team with a losing record. They are overlooking the pitching mismatch and the Tigers elite defense.
