MLB Computer Model Predictions Sunday, June 15
Starting with the Reds vs. Tigers, Saturday’s contest went over the total, but the “Sunday Unders on Over Streak” PRO System signals the under as the best bet to lock in.
This model, accurate 57% of the time since tracking, focuses on Sunday games where the home team follows one or two consecutive overs. The rationale: Sunday games often mark the series finale with earlier start times, meaning teams rest key hitters and pitching staffs are more familiar with opposing lineups. With the total range between 8 and 9.5 runs, recent offensive outperformance tends to regress, making the under a solid value bet.
Adding strength to the under pick is the “Interleague Under Edge” system, also active on Reds-Tigers. Targeting interleague matchups between quality teams (winning records), this PRO System exploits the novelty of unfamiliar opponents combined with mid-to-late season pitching stability and overrated run projections.
With the home favorite often supported by strong bullpens, the under has historically produced consistent profit in similar scenarios.
PRO System Pick: Tigers vs. Reds Under
Turning to the Braves vs. Rockies, the “Unders with Soft Starters and Neutral Winds” system highlights a favorable under opportunity. This model zeroes in on games three or four of a series featuring home starters with low strikeout rates and moderate WHIP, pitched in neutral wind conditions. By this point, hitters have adjusted, and without overpowering pitching or strong winds to aid offense, scoring tends to remain subdued.
This angle is 21-5-2 to the under this season.
PRO System Pick: Rockies vs. Braves Under
It’s not all unders!
The “Twilight Totals” PRO System has an impressive 61% hit rate and is currently active on Sunday’s Guardians vs. Mariners matchup. This proprietary betting model focuses on games that start during the late afternoon to early evening—commonly known as “twilight spots.”
These timeframes create a unique combination of temperature and lighting conditions that subtly boost scoring potential, especially when both teams have a history of hitting the over. The system further hones its edge by factoring in home starters with below-average WHIPs, capitalizing on underappreciated scoring environments.
