Pittsburgh Pirates vs Chicago Cubs Prediction

The Pittsburgh Pirates host the Chicago Cubs in a game where the Pirates hold a significant advantage due to their ace Paul Skenes and the Cubs' prolonged losing streak and offensive woes. Expect the Pirates to continue their strong performance at home against a reeling Cubs team. The pitching matchup strongly favors Pittsburgh, further compounded by Chicago's numerous pitching injuries and poor recent offensive output.

AI-powered prediction

Pittsburgh Pirates host Chicago Cubs on Sunday, part of the 2026 MLB season. Both teams' season records, recent form, and matchup-specific factors are detailed in the stats and prediction sections below.

ATS PREDICTION

Pittsburgh Pirates Win

Predicted: 6-3

โšก66%

The Pittsburgh Pirates, playing at home, are strong favorites against a struggling Chicago Cubs team. Pittsburgh features an elite starting pitcher in Paul Skenes, who boasts a strong 2.89 ERA and 65 strikeouts on the season. The Cubs are in a severe slump, having lost their last 10 games, during which their offense has been anemic, batting a league-worst .185 and scoring only 25 runs. Furthermore, the Cubs' projected starter, Colin Rea, carries a career 4.45 ERA and 1.277 WHIP, presenting a clear pitching disadvantage in this matchup. The Pirates' recent 12-1 victory over the Cubs further highlights the disparity in current form.

SPREAD PREDICTION

Pittsburgh Pirates -1.5 (-1.5)

68%

Given the significant pitching mismatch with Paul Skenes for the Pirates and Colin Rea for the Cubs, coupled with the Cubs' profound offensive struggles during their 10-game losing streak, the Pirates are well-positioned for a multi-run victory. The Cubs' starting pitching has an 8.46 ERA over their last 10 games, making it difficult for them to keep games close. While MLB is high variance, the current form heavily favors the Pirates to cover the 1.5-run spread.

TOTAL PREDICTION

Over 7.5

58%

Despite the Cubs' recent offensive struggles, the Pirates' offense is scoring 4.91 runs per game (6th in MLB) and has a .252 batting average and .333 OBP. Pittsburgh just put up 12 runs on the Cubs in their previous game. While Skenes is expected to limit the Cubs, Colin Rea's higher ERA (4.45) suggests he could give up runs, potentially pushing the total over 7.5 runs, especially considering the Pirates' strong home offense. The Pirates' bullpen has also shown some inconsistency in May with a 5.90 ERA, which could contribute to more runs being scored late in the game.

๐Ÿ† Additional Markets

First 5 Innings Winner

Pittsburgh Pirates

75%

With Paul Skenes (2.89 ERA) starting for the Pirates against Colin Rea (4.45 ERA) for the Cubs, Pittsburgh holds a significant pitching advantage early in the game. Skenes is expected to dominate the struggling Cubs offense through the initial frames, making the Pirates a strong pick to lead after five innings.

Team Total Runs

Pittsburgh Pirates Over 4.5 Runs

65%

The Pirates average 4.91 runs per game and just scored 12 runs against the Cubs. Facing Colin Rea, who has a 4.45 ERA, the Pirates' offense should be able to score at least 5 runs.

To Hit a Home Run

Oneil Cruz (PIT)

55%

Oneil Cruz recently ended a homer drought with his 11th long ball of the year. He's a power hitter in a good matchup against Colin Rea, who has allowed 644 hits in his career.

Race to 3 Runs

Pittsburgh Pirates

68%

Given the Pirates' strong offense and the Cubs' struggling starter, Pittsburgh is more likely to reach three runs first. The Cubs' offense is averaging only 2.5 runs per game during their 10-game losing streak, making it difficult for them to score early.

Winning Margin

Pittsburgh Pirates by 3-5 Runs

50%

While the Pirates are favored, the high-variance nature of MLB makes a blowout less certain than a comfortable victory. Skenes should keep the Cubs offense in check, and the Pirates' lineup can generate enough offense against Rea for a solid win margin.

Betting Angles โ€” Pittsburgh Pirates vs Chicago Cubs

โœ… Moneyline: Pittsburgh Pirates

The Pirates' implied probability at -174 (1.57 decimal) is around 63.5%, but our model estimates a 72% chance of victory given the dominant starting pitching of Paul Skenes and the Cubs' dire form, including a 10-game losing streak and a sputtering offense. This presents a clear value.

โœ… Run Line: Pittsburgh Pirates -1.5

With Paul Skenes on the mound for Pittsburgh and the Cubs' starting pitching posting an 8.46 ERA in their last 10 games, the Pirates have a strong chance to win by more than one run. The Cubs' offensive struggles make it unlikely they'll keep pace, creating a significant edge on the run line.

๐Ÿ’ฐ Sharp Money

Indications are that sharp money is likely on the Pirates given their current form and the significant struggles of the Cubs. Line movement: The moneyline has shifted towards the Pirates (-174 to -182 across various books), reflecting growing confidence in Pittsburgh.

Correlation: Positive - A strong outing from Paul Skenes (leading to more strikeouts) directly correlates with a Pirates win. A Pirates win, especially if they score well against Rea, also contributes to the 'Over' on total runs, as Skenes is expected to limit the Cubs' scoring but the Pirates offense is strong.
