SportsLine model identifies Pirates as key leg in Monday’s MLB parlay
With 12 games on the schedule for July 27, the SportsLine Projection Model has generated betting advice across the Major League Baseball slate, recommending a three-way parlay with a potential payout of nearly +500.
SportsLine’s computer model has simulated all 12 Major League Baseball games scheduled for Monday, July 27, to generate betting advice for the day’s slate. The model highlights a National League Central matchup between the Chicago Cubs and St Louis Cardinals, with the Cubs listed as -120 favourites. Other featured games include the Mariners versus the Rangers, the Orioles versus the Tigers, the Diamondbacks versus the Pirates, and the Guardians versus the Reds.
The model recommends a three-way parlay with a potential payout of nearly +500, specifically backing the Pittsburgh Pirates (-120) against the Arizona Diamondbacks. This selection is grounded in Pittsburgh’s recent performance against Arizona, having won four of the last five games and six of the past eight meetings. The Pirates also won two of three games against Arizona in May.
Pittsburgh will start right-hander Mitch Keller (6-7, 4.90 ERA), who recently pitched five innings allowing three hits and two walks with six strikeouts in a 5-3 win over the New York Yankees. The Diamondbacks will counter with right-hander Merrill Kelly (8-8, 5.12 ERA), who has won three of his last four starts.
In the Cubs-Cardinals matchup, Cubs left-hander David Peterson (5-7, 5.97 ERA) is set to start, while the Cardinals have not yet listed their starter. The Braves (-112) are favoured against the New York Mets, and the Yankees (-148) are road favourites against the Chicago White Sox.
The SportsLine Projection Model simulates every MLB game 10,000 times and entered Week 19 of the MLB season with a 39-23 record on top-rated picks. The model reportedly returned nearly 30 units of profit on home run prop picks in 2025 and claims to have returned more than $10,000 on top-rated picks historically.
