Let’s dive into both PRO picks for MLB Saturday.
MLB Odds for 6/21: Expert Picks for Tigers vs Rays, Diamondbacks vs Rockies
Saturday’s MLB slate begins with a good one between the Tigers and Rays. Both teams boast winning records and potent lineups.
Yet, the “Contrarian Unders for Winning Teams, Later in Series” PRO System suggests betting the game to land under the total number of runs, which, at the time, is listed at 8.5 or 9, depending on the market..
This model thrives in Game 2 or later scenarios when both teams carry winning records, signaling strong pitching matchups and a higher likelihood of low scoring. By fading public perception and capitalizing on market inefficiencies, especially where the offense is forecasted to overperform later in the series, this system has hit at a 57% clip this year, making the under a valuable pick to get things going Saturday.
PRO Pick: Tigers vs. Rays Under
Transitioning to the Arizona Diamondbacks versus Colorado Rockies game in the later window, sharp bettors are taking an early position on the Diamondbacks moneyline.
The Rockies — 17-58 entering the weekend — continue to struggle through a historically awful season. Respected bettors were willing to take what appeared to be a soft number, with an early steam movement on the road side. Pros took a bite of the apple at -195 on the D-backs, tracked by Bet Labs, forcing shops to adjust rather quickly.
