Los Angeles Angels vs Seattle Mariners Predictions Today: Ryan Johnson vs Kade Anderson

Game time: September 26, 2026 at 9:40 PM ET

Venue: T-Mobile Park — Seattle, Washington

Article updated Sep 26, 2:31 AM EDT

By SportsJaw Editorial Team

The Los Angeles Angels will beat the Seattle Mariners, 4-3, in our September 26 forecast. Ryan Johnson's recent run prevention gives Los Angeles the pitching edge, including six innings of one-run ball against Seattle on September 15. Confidence is low: Kade Anderson has the better season ERA, and neither the supplied run line nor total offers a convincing wager. The official recommendation is Pass.

Los Angeles Angels vs Seattle Mariners prediction and best bet

Johnson's recent work makes Los Angeles the narrow choice. His last-five-start ERA is 1.80, compared with Anderson's 5.33, and his three individually documented September outings each lasted six innings. Anderson allowed five earned runs against the Angels on September 14. Those results favor Los Angeles in the starting matchup.

The best betting decision is Pass. Angels +1.5 (-135) offers protection against a one-run defeat, but that protection comes at a price. Recent pitching results make the underdog interesting without making its cover probability clear enough to justify the cost. The projected seven runs also put Under 7.5 in consideration, though the scoring evidence is mixed.

Odds, game time and how to watch

Game: Los Angeles Angels at Seattle Mariners, MLB, Saturday, September 26, 2026.

Time and venue: 6:40 p.m. PDT at T-Mobile Park, according to the official Angels listing.

Broadcast: Mariners.TV and ABTV are listed by the Angels.

Probable starters: Ryan Johnson, right-hander, for Los Angeles; Kade Anderson, left-hander, for Seattle.

SportsJaw moneyline: Angels +165; Mariners -195.

SportsJaw run line: Angels +1.5 (-135); Mariners -1.5 (+115). These are separate bets from the moneyline market above and require evaluating the winning margin as well as the winner. Total: Over 7.5 (-110); Under 7.5 (-110).

Los Angeles Angels outlook

Johnson's season and recent results tell different stories. MLB lists him at 5-9 with a 4.93 ERA and 76 strikeouts in 2026. Covers lists a 1.80 ERA across his last five starts, averaging six innings. The recent stretch is the strongest argument for Los Angeles, although the season ERA warns against treating that improvement as a guarantee.

On September 15 against Seattle, Johnson allowed six hits and one earned run in six innings, with no home runs, no walks and seven strikeouts. Los Angeles won 2-1. That combination of strikeouts and control is encouraging against the same opponent, even though Seattle still collected a hit per inning.

His September 9 start at Boston produced six innings, five hits, three earned runs, two homers, one walk and five strikeouts. On September 4 at Pittsburgh, he allowed four hits and one earned run over six innings, with no homers, two walks and six strikeouts. All runs in those three outings were earned.

The Angels' team results are less decisive: Covers shows a 5-5 record over their last 10 games. They also won 6-4 at Seattle on September 24. Those results keep the forecast grounded in Johnson's form rather than a claim of sustained team dominance.

Seattle Mariners outlook

Anderson's 4.18 season ERA gives Seattle a legitimate counterargument to the Angels forecast. MLB lists his record at 2-2. His six-start season table contains 32 1/3 innings, 31 hits, 15 runs, all earned, four home runs, eight walks and 28 strikeouts. That is a limited workload, so his lower ERA deserves consideration without settling the pitching comparison.

His last five starts carry a 5.33 ERA and an average of five innings. On September 14 at Los Angeles, he surrendered seven hits and five earned runs in 4 1/3 innings. He allowed no home runs or walks and struck out five in Seattle's 6-4 loss. The Angels scored against him without needing a homer or a free pass.

Earlier, on September 9 against Texas, Anderson delivered six innings with six hits, one earned run, one homer, one walk and five strikeouts. That outing shows why projecting another difficult start against Los Angeles would be too aggressive.

On September 3 against the Athletics, he allowed seven hits and four earned runs in five innings, with one homer, two walks and three strikeouts. His range of September outcomes makes Seattle dangerous but difficult to trust for a comfortable win. Another performance resembling the Texas start could reverse the projected result.

Key matchup factors

Starter length could shape the game. Johnson's last-five average is one inning longer than Anderson's, potentially leaving fewer innings for the Angels' bullpen. That is a workload implication, not a claim that Los Angeles has the stronger relief staff.

SportsJaw's September 26 consensus update, timestamped 00:31:58 UTC, showed Angels +165 leading community moneyline selections at 57%. Qualified handicappers also favored that selection at 57%; those figures describe separate groups, not Los Angeles' win probability. Community total selections favored Over 7.5 at 100%, which is sentiment rather than scoring evidence.

The missing offensive splits against each starter's handedness and bullpen availability keep the pitching comparison from becoming a complete betting case.

Los Angeles Angels vs Seattle Mariners spread prediction

Run-line recommendation: Pass on Angels +1.5 (-135) and Mariners -1.5 (+115). Los Angeles is the more appealing side of this matchup, and the projected one-run Angels victory would cover +1.5. But a score forecast is only one possible outcome, not a measure of how often the bet wins.

Johnson's recent results argue against laying runs with Seattle. His 4.93 season ERA and Anderson's strong Texas outing temper enthusiasm for paying -135 on Los Angeles. Neither price earns an official recommendation.

Los Angeles Angels vs Seattle Mariners total prediction

Total recommendation: Pass on Over 7.5 (-110) and Under 7.5 (-110). The Angels 4, Mariners 3 forecast sits below the total, with Johnson's recent run prevention supplying the clearest Under argument.

Anderson's uneven September results pull the other way. Covers also lists the Angels' last-10 totals record at seven overs, two unders and one push. That team trend is a useful counterweight, but it spans different pitching matchups. Without a firmer offensive and bullpen picture, the projected seven runs are too thin a reason to buy the Under.

Los Angeles Angels vs Seattle Mariners projected score

Game forecast: Los Angeles Angels 4, Seattle Mariners 3. Johnson's recent combination of innings, control and run prevention earns Los Angeles the nod. His September 15 performance against Seattle makes that preference more specific than simply backing the pitcher with the lower recent ERA.

The strongest counterargument is Anderson's better season ERA, reinforced by his six-inning, one-run outing against Texas. Johnson's season results are also substantially weaker than his recent stretch. Those competing signals make this a low-confidence Angels forecast. The run line and total are both passes, and the single official SportsJaw betting recommendation is Pass. Picking Los Angeles to win does not require buying its spread.
