The Houston Astros travel to Seattle to face the Seattle Mariners in an American League West matchup at T-Mobile Park on April 10, 2026. Both teams enter this game struggling early in the season and are looking to regain momentum in the division race.
Houston has shown strong offensive numbers so far, but the team has faced serious pitching problems and recently dropped four straight games. Seattle, on the other hand, has been strong on the mound but continues to struggle with its offense.

Team Form and Early Season Storylines
Houston Astros: Strong Offense but Pitching Concerns
Houston’s lineup has been productive despite the losing streak. The Astros have one of the best offensive outputs in the league early in the season.
| Offensive Metric | Astros |
|---|---|
| OPS | .825 |
| Team Batting Average | .271 |
| On-Base Percentage | .371 |
| Slugging Percentage | .453 |

The Astros have been among the most efficient teams offensively. However, their pitching has struggled badly.
| Pitching Metric | Astros |
|---|---|
| ERA | 6.05 |
| WHIP | 1.59 |
| HR Allowed per 9 innings | 1.59 |
| Walk Rate | 13.7% |
These pitching issues have forced Houston to rely heavily on its offense to stay competitive in games.
Seattle Mariners: Elite Pitching but Weak Batting
Seattle’s biggest issue this season has been offense. The lineup has struggled to produce runs and has posted some of the lowest hitting numbers in the league.
| Offensive Metric | Mariners |
|---|---|
| OPS | .581 |
| Batting Average | .184 |
| OBP | .280 |
| SLG | .301 |
Several key hitters have struggled to start the season, including Julio Rodriguez, Cal Raleigh, and Josh Naylor.
Despite the offensive issues, Seattle’s pitching staff has been one of the best in baseball.
| Pitching Metric | Mariners |
|---|---|
| Team ERA | 2.62 |
| WHIP | 0.95 |
| K-BB Percentage | 20.8% |
| FIP | 2.82 |
This strong pitching performance has kept the Mariners competitive in low-scoring games.
Probable Starting Pitchers
The pitching matchup highlights two right-handers who have had very different starts to the season.
| Team | Pitcher | Record | ERA | WHIP | Strikeouts |
|---|---|---|---|---|---|
| Astros | Tatsuya Imai | 1-0 | 4.32 | 1.56 | 13 |
| Mariners | Emerson Hancock | 1-1 | 0.71 | 0.55 | 14 |
Tatsuya Imai – Houston Astros
Imai is making his third MLB start after moving from Japan. His debut was difficult, but his second outing was impressive when he threw 5.2 scoreless innings and recorded nine strikeouts.
Through two starts he has shown strong strikeout ability, collecting 13 strikeouts in just over eight innings.
Emerson Hancock – Seattle Mariners
Hancock has been outstanding early in the season. Across his first two starts he has allowed only one earned run in nearly 13 innings while striking out 14 batters.
His strong command and ability to limit base runners have made him one of Seattle’s most effective pitchers so far.
Key Players to Watch

| Player | Recent Form |
|---|---|
| Christian Walker | Hit safely in five straight games |

Seattle Mariners
| Player | Recent Form |
|---|---|

Match Prediction
This game features two teams with completely different strengths. Houston has one of the most productive offenses in the league but continues to struggle with pitching issues. Seattle, meanwhile, has elite pitching numbers but has not found consistency at the plate.
Emerson Hancock’s strong early season form gives the Mariners an advantage on the mound, especially against an Astros pitching staff that has allowed too many runs recently. Seattle’s home-field advantage at T-Mobile Park also adds another important factor.
If the Mariners’ pitching continues its dominant performance and the offense produces even a few timely runs, Seattle should have a good chance to secure the win.
Houston still has the ability to score runs quickly, so the game could remain competitive, but Seattle’s pitching strength makes them slightly favored in this matchup.
