MLB ATS Standings: Run Line & First Five Betting Records
Updated October 21, 2026
Updated October 21, 2026
MLB ATS standings show how teams perform against the betting line, offering a different perspective than traditional win-loss records. Run-line results, first-five-innings records, and cover percentages can all help identify trends that regular standings miss.
ATS.io has tracked baseball betting performance across these markets, including the Texas Rangers' standout first-five record during the 2023 season.
This page explains how MLB ATS standings work, revisits that historical record, and shows how bettors can put the numbers into context.
ATS stands for against the spread. In baseball, this generally refers to a team's performance against the run line, although betting records can also be tracked across first-five-innings markets and alternative handicaps.
The standard MLB run line is 1.5 runs. Favorites typically need to win by at least two runs to cover -1.5, while underdogs cover +1.5 by winning outright or losing by one run.
First-five standings focus on the score after five innings, making them especially relevant when comparing starting pitchers.
Statistic | What It Tells You |
|---|---|
W | Number of winning bets |
L | Number of losing bets |
P | Number of pushes |
Cover % | Percentage of graded decisions won |
Full-Game ATS | Performance against the full-game run line |
F5 Record | Betting results through the first five innings |
ROI | Return on investment based on actual betting prices |
A team with a strong overall record won't necessarily have a strong ATS record. Winning by one run is enough for a moneyline bet, but it won't cover a -1.5 run line.
The reverse is also true. A team can lose a game and still cover +1.5.
One of the more notable first-five betting trends in 2023 involved the Texas Rangers.
On August 12, 2023, The Hamilton Spectator published an MLB parlay betting article citing ATS.io data. It identified Texas as the team with baseball's best first-five record at that point in the season.
The reported record was 69-36-11.
Metric | Historical Record |
|---|---|
Team | Texas Rangers |
Season | 2023 |
Record | 69-36-11 |
Wins | 69 |
Losses | 36 |
Pushes | 11 |
Games tracked | 116 |
Win percentage excluding pushes | 65.7% |
Source: ATS.io historical figures cited by The Hamilton Spectator on August 12, 2023. This is a snapshot of the season at that date, not a final-season record.
The original article also referenced Texas covering a particular line in 80 of 116 games, equivalent to 69.0%.
That figure appears to represent a separate betting calculation and should not be confused with the 69 wins recorded in the 69-36-11 standings figure.
Texas had one of MLB's most productive offenses in 2023, led by Corey Seager, Marcus Semien, Adolis García, and Nathaniel Lowe.
The lineup could generate runs early, while the rotation included Nathan Eovaldi and Jon Gray. Texas also strengthened its pitching staff by acquiring Jordan Montgomery and Max Scherzer during the season.
That combination made the Rangers an interesting team to follow in first-five markets.
The distinction matters because first-five bets are settled before the final four innings. A strong starting pitcher and productive early offense can give a team an advantage even when its bullpen is less reliable.
Texas eventually won the 2023 World Series, but its first-five betting record was already attracting attention months before the postseason.
Full-game and first-five standings measure different periods of a baseball game.
Market | What Counts | Main Considerations |
|---|---|---|
Full-game run line | Final game score under applicable settlement rules | Starting pitchers, bullpens, offense |
First-five moneyline | Score after five innings | Starting pitchers, early offense |
First-five run line | Score after five innings, adjusted for the handicap | Pitching matchups, early run differential |
First-five total | Combined runs through five innings | Starting pitchers, lineups, scoring conditions |
A team might have an excellent full-game record because of its bullpen, while struggling through the opening five innings.
Another team may frequently take early leads but fail to maintain them.
Comparing both records helps reveal where a team's strengths are concentrated.
For upcoming games, the MLB matchup pages provide a starting point for comparing teams, available odds, and pitching matchups.
Cover percentage measures the proportion of winning bets among graded wins and losses.
Pushes are normally excluded.
Cover % = Wins ÷ (Wins + Losses) × 100
Using the Rangers' historical 69-36-11 record:
69 ÷ (69 + 36) × 100 = 65.7%
The 11 pushes are excluded because they are neither wins nor losses.
This calculation is different from dividing wins by all 116 games, which would produce 59.5%.
Keeping these methods separate is important when comparing records across sportsbooks and statistics providers.
A winning ATS record doesn't automatically translate into betting profit.
The odds determine how frequently a wager must win to break even.
Betting Odds | Break-Even Percentage |
|---|---|
-150 | 60.0% |
-120 | 54.5% |
-110 | 52.4% |
+100 | 50.0% |
+120 | 45.5% |
A bettor consistently taking -110 needs to win approximately 52.4% of those wagers to break even.
At -150, the required rate rises to 60%.
That's why a team's cover percentage should be evaluated alongside its historical betting prices. A strong record at expensive odds may offer less value than a more modest record at favorable prices.
The most useful betting records are those supported by an identifiable reason for a team's performance.
Starting pitching has a particularly strong influence on first-five markets.
Look at strikeout rates, walk rates, recent workload, and how a pitcher performs against the opposing lineup.
A strong starter facing a vulnerable offense may provide a better F5 opportunity than a full-game bet.
Bullpens are a major consideration in full-game betting.
Teams with reliable late-inning pitching can protect narrow leads, while clubs with inconsistent relief pitching may struggle to finish games.
Comparing full-game and F5 records can help identify that difference.
Run differential provides more context than wins and losses alone.
A team that regularly wins by multiple runs may be more attractive at -1.5 than a club that relies on close victories.
However, the price attached to the run line still matters.
Ballpark dimensions, travel schedules, and batting-order differences can affect team performance.
Home and road ATS splits may reveal useful trends, although small samples can exaggerate the significance of short-term results.
Historical records become less relevant when a team's roster or pitching rotation changes.
Before placing a wager, compare the available odds with current lineups, pitching assignments, injuries, and recent form.

ATS records are most useful as a starting point for further analysis.
For example, consider a team with a strong first-five record but a mediocre full-game ATS record.
That difference might suggest the starting rotation performs well while the bullpen struggles.
Another club might have an impressive overall record but a poor -1.5 run-line record because it wins a high percentage of its games by one run.
Neither trend guarantees future results. The goal is to understand what drives the numbers and assess whether the available betting price reflects that information.

ATS stands for against the spread. In MLB, it usually refers to a team's record against the run line, which is commonly set at 1.5 runs.
A first-five record tracks betting results through the opening five innings of a game. Depending on the market, it may refer to moneyline results or performance against a first-five run line.
According to historical ATS.io figures cited by The Hamilton Spectator on August 12, 2023, Texas had a 69-36-11 first-five record at that point in the season.
It depends on the odds. At -110, a cover percentage above approximately 52.4% is needed to produce a positive return over time, assuming equal-sized wagers at that price.
Yes, when the handicap is a whole number and the adjusted score lands exactly on the line. Standard full-game run lines of ±1.5 cannot push based on the final score.
Each market has different advantages. First-five betting places greater emphasis on starting pitchers, while full-game betting also depends heavily on bullpen performance.
MLB ATS standings provide valuable context beyond traditional win-loss records. Full-game run lines reveal how often teams cover the handicap, while first-five records offer a closer look at starting-pitching performance and early offense.
The Texas Rangers' 2023 first-five record is a useful historical example. Their strong early-game performance became a notable betting trend and earned attention beyond ATS.io.
→ Our Take: The strongest use of MLB ATS standings is identifying why a team consistently covers a particular market. Historical results help establish the pattern, but starting pitchers, current form, and available odds determine whether that information has betting value today.
