The Mariners season in numbers
- Record
- 76-86
- Division
- 3 of 5
- Run diff.
- -58
- Expected wins
- 75
- Home
- 43-38
- Road
- 33-48
Across 162 games the Mariners scored 664 times and allowed 722 runs, a run differential of -58. That works out to 4.10 runs scored and 4.46 allowed per game, against a league average of 4.48 for each side. Based on those runs, a typical team would have won about 75 games, so the Mariners finished 1 win above that mark. That is close enough to say the Mariners record reflects how well they actually played.
At home the Mariners went 43-38, on the road 33-48. That home edge is wider than most, so the ballpark matters more than usual when the Mariners are priced at home. Against left-handed starters they were 26-29, against right-handers 50-57, and they closed the regular season 6-4 over the last ten games, ending on a 2-game winning streak.
Recent form: the last 10 games
In their last 10 regular-season games the Mariners went 6-4, scoring 4.7 and allowing 4.4 runs per game. 7 of those 10 games finished above 9 total runs, 3 were decided by a single run, and the widest margin was 7-0 at home against HOU. The chart plots each of those Mariners games, runs scored above the line and runs allowed below it.

The Mariners in the first inning
The first inning stayed scoreless in 45.7% of Mariners games, compared with 49.4% across the league. The Mariners scored in the first inning 30.2% of the time and allowed a first-inning run in 34% of games. That is close to the league norm. The NRFI Lab puts the Mariners next to every other team and starter on the same split.
How to read the Mariners numbers
Reading these Mariners numbers before a game: the run differential and expected wins say more about team quality than the raw record, the home and road split shows how much T-Mobile Park helps, and the last-ten totals show whether recent Mariners games have run high or low. With 3 one-run games in the last ten, the Mariners are a good example of why the run line at -1.5 or +1.5 can price very differently from the moneyline. None of these Mariners figures predicts a single game, and no bet is ever a sure thing.
T-Mobile Park, home of the Mariners
The Seattle Mariners play their home games at T-Mobile Park in Seattle, WA, a ballpark with a retractable roof, at an elevation of 10 feet. Games there averaged 7.94 total runs, an index of 0.89 against the league average, which makes T-Mobile Park one of the tougher places to score. When the T-Mobile Park roof is open, wind and temperature come back into play. The ballpark scoring page ranks all 30 parks.
Mariners injured list
7 players are on the Mariners injured list: Brennen Davis (CF, IL 60-Day), Colt Emerson (SS, IL 60-Day), Logan Evans (P, IL 60-Day), Luke Raley (RF, IL 60-Day), Matt Brash (P, IL 60-Day), Nick Davila (P, IL 60-Day), plus 1 more.
