MLB Picks Today: Predictions & Best Bets for August 29, 2026 | SharpSide

Saturday presents a full 17-game MLB slate, offering a wide array of matchups for analysis. SharpSide's models detect several significant divergences from market consensus, particularly in three contests today: the Miami Marlins at Washington Nationals, the Chicago White Sox visiting the Minnesota Twins, and the Pittsburgh Pirates in St. Louis against the Cardinals. The largest single run-edge the model identifies today is a 1.8-run side edge favorable to the Miami Marlins in their matchup against the Nationals. This brief is current as of publication and will refresh at 11:30 am Eastern based on new analytics, weather factors, pitching changes, and line movement. Today's Best Bet is highlighted immediately below.

Today's Best Bet: Baltimore Orioles ML

Today's highest-confidence pick from SharpSide's model is the Baltimore Orioles Moneyline against the Athletics. Our model projects the Orioles to win by a moderate margin of 1.2 runs, with a final score of 5.3 to 4.1. This projection is largely in line with what the market implies, indicating that this is a conviction play for the model, not necessarily a significant edge against current pricing. While the margin is not exceptionally wide, the model identifies this as the game it is most sure of the outcome. Best Bet: Baltimore Orioles ML (-142)

Miami Marlins @ Washington Nationals

The SharpSide model identifies a significant market divergence in today's contest between the Miami Marlins and the Washington Nationals. While the market consensus projects the Nationals as a 1.5-run favorite, our model sees a tighter game, favoring the Miami Marlins by 0.3 runs. This represents a 1.8-run shift in favor of the Marlins compared to market expectations. Miami sends Sandy Alcantara to the mound, who brings a strong 3.78 FIP and a 0.295 xwOBA-against, indicating his ability to limit hard contact. His 0.88 HR/9 is also well below the league average of 1.20, suggesting good home run suppression. Opposing him for Washington is Cade Cavalli, who has a 3.41 FIP and a 0.303 xwOBA-against, also demonstrating solid performance metrics. Both starters project to allow weak contact, suggesting a pitching-dominant game for their respective opponents. Alcantara typically pitches deeper into games, averaging 6.77 IP per start, while Cavalli averages 5.56 IP. The Washington Nationals' bullpen presents a vulnerability. Their season relief ERA is 4.86, significantly above the league average of 4.10, and their fatigue index of 0.32 indicates they are taxed. This condition causes a substantial +0.75 run nudge to the Miami Marlins' projected runs late in the game. In contrast, the Marlins' bullpen holds a 3.99 ERA, slightly better than the league average. In the second game of this four-game series, the Nationals won the opener decisively, 9-2. Both teams enter this game with struggling recent form, each holding a 4-6 record over their last 10 outings. How the model decided: The biggest factor favoring Miami Marlins is Washington Nationals's vulnerable 4.86 bullpen ERA, which is worse than the roughly 4.10 league average and improves Miami Marlins's scoring outlook. Lean: Miami Marlins ML (-106)

Chicago White Sox @ Minnesota Twins

The SharpSide model projects the Chicago White Sox as 0.2-run favorites against the Minnesota Twins, scoring them 4.5–4.3. This stands in contrast to the market consensus, which favors the Twins by 0.9 runs (5.2–4.3). This represents a 1.1-run margin shift more favorable to the Chicago White Sox than the market implies. Chicago starts Erick Fedde, who carries a 5.25 FIP and a 0.330 xwOBA-against, suggesting he allows harder contact than league average and is prone to home runs with a 1.67 HR/9. His average workload of 4.67 IP per start indicates he exposes his bullpen heavily. Minnesota counters with Bailey Ober, whose 4.74 FIP and 0.333 xwOBA-against are similarly concerning, as is his 1.50 HR/9. Both starters present opportunities for the opposing offenses. The White Sox bullpen is performing above average with a 3.79 ERA, while the Twins bullpen is struggling at 4.89, well above the 4.10 league average. This bullpen discrepancy contributes a +0.30 run nudge to the White Sox' projected runs. In the second game of this three-game series, the White Sox took game one by a 7-4 score. Both teams have experienced mixed recent form; the White Sox are 6-4 in their last 10, while the Twins are 4-6. How the model decided: The biggest factor favoring Chicago White Sox is Minnesota Twins's vulnerable 4.89 bullpen ERA, which is worse than the roughly 4.10 league average and improves Chicago White Sox's scoring outlook. Lean: Chicago White Sox ML (+105)

Pittsburgh Pirates @ St. Louis Cardinals

For the matchup between the Pittsburgh Pirates and the St. Louis Cardinals, SharpSide's model projects the Pirates to win by a narrow 0.1-run margin (4.0–3.9). This contrasts with the market, which favors the Cardinals by 0.9 runs (4.7–3.8). The model sees this game as 1.0 runs more favorable to the Pittsburgh Pirates than the consensus. Pittsburgh will feature Lake Bachar, who is expected to have a short outing, averaging only 2.33 IP over his 6 starts. This game is effectively a bullpen game for the Pirates. St. Louis sends Kyle Leahy to the mound, with a 3.49 FIP and a 0.85 HR/9, indicating strong control and home run suppression. However, his 0.336 xwOBA-against suggests he allows harder contact. He averages 5.10 IP per start. The Pirates' bullpen has been performing near league average with a 4.09 ERA and is well-rested (fatigue index -0.12), contributing a -0.25 run nudge to the Cardinals' projected runs. The Cardinals' bullpen, however, has a 4.47 ERA (worse than league average) and is taxed (fatigue index 0.25), leading to a +0.50 run nudge to the Pirates' projected runs. St. Louis is also missing core hitter Masyn Winn tonight, docking approximately 0.09 runs from their offensive projection. In game two of this three-game series, the Cardinals won the opener 4-1. Both teams come in with 4-6 records over their last 10 games, indicating struggling recent form. How the model decided: The biggest factor favoring Pittsburgh Pirates is St. Louis Cardinals's vulnerable 4.47 bullpen ERA, which is worse than the roughly 4.10 league average and improves Pittsburgh Pirates's scoring outlook. Lean: Pittsburgh Pirates ML (+108)

First Five Innings: Pittsburgh Pirates @ St. Louis Cardinals (F5 UNDER)

The SharpSide model indicates a strong lean to the F5 UNDER for the Pittsburgh Pirates and St. Louis Cardinals game. Our model projects an F5 total of 2.78 runs, dramatically lower than the market-implied F5 total of 4.42 runs. This 1.64-run difference highlights a significant edge. Pittsburgh's Lake Bachar, despite his short average outing, has a blended F5-only ERA of 2.89 against his full-season 3.70 ERA. St. Louis's Kyle Leahy projects with a blended F5-only ERA of 2.95, also indicating strong early-game pitching. Pittsburgh's offense has been lucky on balls in play (0.313 BABIP), leading the model to regress their early offense downward by 0.36 runs. Conversely, the Cardinals' offense has been unlucky (0.282 BABIP), resulting in an upward regression of 0.12 runs. The park multiplier is also a pitcher-friendly 0.930. Lean: F5 UNDER 4.0 total

Batter Prop: Matt Shaw Over 0.5 Hits

SharpSide has identified compelling line movement on Matt Shaw's Hits Over 0.5 prop in the Cincinnati Reds at Chicago Cubs game. The market price has moved from -148 to -180, indicating a significant shift of +4.6 probability-points toward the OVER from opening. This aggressive adjustment across multiple books often signals sharp money entering the market, suggesting high confidence in Shaw to record at least one hit tonight. Lean: Matt Shaw Over 0.5 Hits (-180)

How the model decided

Today's SharpSide model divergences from market consensus were primarily driven by bullpen disparities, BABIP luck regression, and individual pitcher metrics. The Miami Marlins' lean was heavily influenced by the Washington Nationals' taxed bullpen, which added a significant 0.75 runs to Miami's projection. The Chicago White Sox pick saw contributions from the Minnesota Twins' struggling bullpen and Chicago's own unlucky BABIP which pushed their offense up by 0.05 runs. For the Pittsburgh Pirates, the model identified both the Cardinals' taxed bullpen and the Pirates' rested pen as major factors, along with the Cardinals' Masyn Winn injury. The "Favorite coming off a blowout win (margin ≥ 5)" system also fired on the Chicago White Sox, historically providing a +1.3pp lift with a 58.2% hit rate. The model also considered advanced Sabermetric data, systems trends, and other analytics.
