MLB Picks Today: Predictions & Best Bets for July 31, 2026 | SharpSide

A 15-game MLB slate awaits on Friday, offering a series of intriguing matchups for sharp bettors. SharpSide's model identifies a significant market divergence in the Arizona Diamondbacks @ Cleveland Guardians game, projecting a total run differential of +1.1 runs over consensus, the largest total edge of the day. Our daily brief, refreshing at 11:30 am Eastern, integrates all new analytics, weather factors, pitching changes, and line movement to refine these projections. Today's Best Bet is highlighted next.

Today's Best Bet: Pittsburgh Pirates ML

Today's Best Bet represents SharpSide's single highest-confidence play on the slate. Our model projects the Pittsburgh Pirates to win their matchup against the Cincinnati Reds with a substantial 1.3-run margin (5.0–3.7). This forecast aligns roughly with the market's implied margin, indicating that while there isn't a significant edge against the consensus line, our conviction in the Pirates' victory is exceptionally strong. Even with similar pricing, this is the game where SharpSide's proprietary analytics are most decisive about the outcome. Best Bet: Pittsburgh Pirates ML (-133)

Miami Marlins @ New York Mets

The SharpSide model projects the Miami Marlins to defeat the New York Mets 4.7-4.4, leading to a lean on Miami at +111. This diverges from a market consensus of 3.8-4.7, indicating the model sees an additional +0.6 runs on the total compared to market while shifting the margin by -1.2 runs toward New York's projected home margin. Marlins starter Janson Junk brings a 4.36 FIP, suggesting his earned run allowance is slightly above league average, and a 0.310 xwOBA-against, indicating he permits contact quality close to the league average. Freddy Peralta, starting for the Mets, counters with a 4.46 FIP and a 0.302 xwOBA-against, meaning he allows slightly better contact quality than Junk, but his FIP is marginally worse than Junk's. Both starters average under 5.0 IP per start, heavily exposing their bullpens. The Mets bullpen, despite a strong 3.82 ERA, enters this contest taxed with a 0.22 fatigue index, which the model adjusts to concede more runs to the Marlins late. Compounding the Mets' outlook, star hitter Juan Soto is absent tonight, docking roughly 0.30 runs from their offensive projection. Heading into Game 2 of 4, the Mets took the opener 4-2. The Marlins are struggling with a 3-7 record over their last 10 games, while the Mets are middling at 5-5. There are no notable park or weather conditions influencing run scoring. How the model decided: The model’s lean toward the Marlins was significantly driven by the Mets' taxed bullpen, which is expected to concede more runs late in the game. The absence of Juan Soto also reduced the Mets' offensive projection. While the Marlins' 0.299 BABIP indicates they have been lucky on balls in play, prompting a -0.13 run regression, this factor was outweighed by the Mets' internal issues, including their 0.275 BABIP suggesting they have been unlucky and are due for a +0.20 run addition. The largest driver was the cumulative effect of the Mets' injury and bullpen fatigue, increasing Miami's run expectation. Lean: Miami Marlins ML (+111)

Washington Nationals @ Atlanta Braves

The SharpSide model projects the Washington Nationals to edge the Atlanta Braves 4.9-4.7, presenting a lean on the Nationals ML at +102. This contrasts with a market consensus of 4.1-5.0, implying a +0.5 run edge on the total compared to market and a -1.1 run shift toward Atlanta's projected home margin. Foster Griffin takes the mound for the Nationals, offering a solid 3.94 FIP and a 0.305 xwOBA-against, both of which are near league average and suggest he limits hard contact effectively. For the Braves, Bryce Elder starts with a 4.47 FIP, indicating he generally allows more earned runs than league average, and a 0.307 xwOBA-against, consistent with average contact quality. Griffin's 6.33 IP/start provides more stability than Elder's 5.21 IP/start. The Braves' bullpen, despite a strong 3.41 season relief ERA, is heavily taxed with a 0.47 fatigue index, leading to a model run nudge of +0.50 against them. This fatigue factor is a primary reason the model sees more runs for Washington, who have a weaker bullpen (5.00 ERA) but are less fatigued (0.11 fatigue index). Heading into Game 2 of 4, the Braves secured the first game with a narrow 5-4 victory. Both teams exhibit average recent form, with the Nationals at 5-5 and the Braves at 6-4 over their last 10 games. Park and weather conditions are neutral tonight. How the model decided: The primary factor driving SharpSide's lean toward the Nationals is the significantly taxed Atlanta bullpen, which the model projects to surrender an additional 0.50 runs tonight. Furthermore, Foster Griffin’s more efficient 3.94 FIP compared to Bryce Elder’s 4.47 FIP contributes to suppressing the Braves' offensive output. While the Braves' 0.285 BABIP luck suggests they are due for a +0.08 run addition, the bullpen's fatigue and starter's quality for Washington were more influential. The largest driver for the lean was the Braves' taxed bullpen, boosting the Nationals' run projection. Lean: Washington Nationals ML (+102)

Arizona Diamondbacks @ Cleveland Guardians

SharpSide's model projects a higher-scoring affair between the Arizona Diamondbacks and Cleveland Guardians, predicting a 4.5–5.1 final score. This marks a +1.1 run total edge compared to the market consensus of 3.8–4.7, and a -0.3 run margin shift toward the Guardians, leading to a lean on the OVER 8.5 total at -116. Arizona starter Mitch Bratt, in a small sample of 15.7 IP, shows concerning metrics with a 7.44 FIP and a very high 2.30 HR/9, indicating significant struggles with earned runs and home runs allowed. His 0.344 xwOBA-against suggests he yields hard contact consistently. Cleveland's Tanner Bibee presents a more stable 4.57 FIP and 1.44 HR/9, which are still above league average in terms of earned run prevention and home run suppression, along with a 0.325 xwOBA-against, indicating he also allows harder contact than average. Bratt's short average of 3.92 IP per start heavily exposes the Diamondbacks' bullpen, which, despite a 4.15 ERA, is expected to absorb significant innings. The Guardians' bullpen, with a strong 3.71 ERA, is in better shape than the Diamondbacks' pen. This is the series opener for both teams. The Diamondbacks are 6-4 in their last 10, while the Guardians are 4-6. There are no notable park or weather conditions influencing run totals. How the model decided: The model's confident lean on the OVER is primarily driven by the poor peripheral statistics of both starting pitchers, particularly Mitch Bratt's small sample 7.44 FIP and 2.30 HR/9, which heavily increases the Guardians' run projection. Furthermore, both offenses have been unlucky on balls in play; the Diamondbacks' 0.279 BABIP adds 0.16 runs to their projection, and the Guardians’ 0.277 BABIP adds 0.17 runs to theirs. The short workload of Bratt also exposes the Diamondbacks' bullpen, further contributing to a higher total. The largest driver pushing the total up is Mitch Bratt's poor isolated pitching metrics. Lean: OVER 8.5 total (-116)

First Five Innings: Washington Nationals @ Atlanta Braves (F5 UNDER)

The model identifies a compelling F5 UNDER opportunity in the Washington Nationals @ Atlanta Braves game. Nationals starter Foster Griffin brings an F5-only ERA of 3.07 when blended with his full season stats, indicating strong early-game performance. Atlanta's Bryce Elder counters with a blended F5-only ERA of 4.12. The model projects a combined F5 total of 3.42 runs, which is significantly lower than the market's implied F5 total of 4.73 runs. The offensive context provides additional support, with the Nationals exhibiting neutral BABIP luck, while the Braves, despite being unlucky on balls in play with a 0.285 BABIP, receive only a minor +0.08 run regression for their offense. The model's low F5 total is heavily influenced by quality starter performance and relatively average offensive conditions in the early frames. Lean: F5 UNDER 4.5 total

How the model decided

Today's top divergences from market consensus were primarily driven by a combination of starting pitcher performance metrics, bullpen fatigue, and advanced offensive regressions. In the Miami Marlins @ New York Mets game, the Mets' taxed bullpen alongside the absence of Juan Soto created a value opportunity on the Marlins' moneyline. The Washington Nationals' lean was bolstered by Foster Griffin's solid FIP and the highly fatigued Atlanta bullpen. For the Arizona Diamondbacks @ Cleveland Guardians game, the poor underlying pitching metrics of both Bratt and Bibee, combined with both teams experiencing unlucky BABIPs ripe for positive regression, pushed the model toward a higher total. The model also considered advanced Sabermetric data, systems trends, and other analytics.
