The strongest MLB betting trends on the board for Monday, September 21: streaks, props and NRFI angles pulled from our graded-results database and checked against the current lines. Updated every morning through the season.
Today's board: a three-game Monday with no writeup
Three games tonight, Blue Jays at Orioles (6:35 PM ET), Nationals at Tigers (6:40) and Twins at Giants (9:45), and none of them produced a trend that cleared our bar this morning, so there's no daily article today. The board is back Tuesday, when the Rays visit the Yankees for a 1:05 PM ET start and the final week of the regular season gets going.
Football fills the night: Giants at Rams on Monday Night Football at 8:15 PM ET, with the Giants' third-quarter and second-half records plus the quarter markets in our Monday Night Football board, and the week's full read on the NFL betting trends page.
How this board gets built
We track graded results for every player prop and team market across MLB, every day. A trend only makes this page when the record is real (no cherry-picked windows), the streak is current, and the number is checked against today's actual line. We also replay every record at today's number, so a trend built at a different line doesn't get sold as the same bet. Games where the starting pitcher isn't settled get left off rather than guessed at, and games that have already started never appear. Records describe what has already happened; they never guarantee what happens next. If a term on this page is new to you, our betting terminology guide covers all of it, and our EV calculator shows what any price really pays.
FAQ
How often is this page updated?
Every morning during the MLB season, after our overnight results grade and the day's lines load. Game-day articles go deeper on each slate and are linked above as they publish.
What is an MLB betting trend?
A repeated, graded result in one specific market: a hitter clearing the same prop line game after game, a team's games opening scoreless, a total leaning one direction. We report the exact market, the exact record, and today's price, so you can judge it yourself.
Are these picks?
No. WagerSharp is editorial trend analysis, not a picks service. We surface what the data shows and flag angles worth a look; the decision, the line shopping and the bet sizing are yours. Our line shopping guide explains why the number you bet matters as much as the side.
