St. Louis Cardinals vs Chicago Cubs Prediction

The St. Louis Cardinals host the Chicago Cubs in what is expected to be a challenging divisional matchup. The Cubs are in a severe slump, having lost eight straight games and struggling significantly with offensive production and numerous pitching injuries. The Cardinals are also in a minor slump but appear to be in a better overall position, especially playing at home against a depleted Cubs squad.

AI-powered prediction

St. Louis Cardinals 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

St. Louis Cardinals Win

Predicted: 5-3

66%

The St. Louis Cardinals, despite a recent slump of losing five of their last six games, hold a slightly better overall record (29-24) compared to the Chicago Cubs (29-26). More significantly, the Cubs are currently enduring a severe eight-game losing streak and have gone 2-8 in their last ten outings, indicating a significant downturn in form. The Cubs also face a more extensive list of pitching injuries, with several key arms like Justin Steele, Matthew Boyd (rehabbing on May 31st), and Edward Cabrera (out until June 5th) either out or limited, which severely impacts their pitching depth. While the Cardinals have their own injuries, their rotation has shown more stability with pitchers like Michael McGreevy and Andre Pallante performing well. Playing at home, the Cardinals are in a better position to capitalize on the Cubs' current struggles and depleted pitching staff.

SPREAD PREDICTION

St. Louis Cardinals -1.5 (-1.5)

65%

Given the Chicago Cubs' pronounced offensive struggles, including being shut out and held to just two hits in recent games, and their significant pitching injuries, the St. Louis Cardinals are well-positioned to win by more than one run. The Cubs' recent 12-1 loss to the Pirates further highlights their vulnerability. If the Cardinals' pitching can maintain a reasonable level of performance, their offense should be able to generate enough runs against a weakened Cubs pitching staff to cover a standard -1.5 run line.

TOTAL PREDICTION

Under 8.5

60%

The Cubs' offense has been notably cold during their recent losing streak, with multiple low-scoring outputs, including being shut out in one recent outing. While both teams have experienced some higher-scoring games recently, the overall trend for the Cubs' offense suggests difficulty in putting up many runs. The Cardinals' pitching, despite some recent struggles, has some bright spots in their rotation. Therefore, a total score leaning towards the under is anticipated, as the Cubs' offensive woes are likely to suppress the overall run count, even against a Cardinals team that has also given up runs.

Betting Angles St. Louis Cardinals vs Chicago Cubs

💰 Sharp Money

Sharp money would likely be on the Cardinals, especially if the line doesn't fully account for the Cubs' current struggles and injury woes. The prolonged losing streak for the Cubs is a major red flag for professional bettors. Line movement: Expect the line to move further in favor of the Cardinals if the Cubs' losing streak continues in the games leading up to May 31st, or if any further negative news regarding Cubs' injuries emerges. The total might see slight downward movement given the Cubs' offensive struggles.
