Kirby has demonstrated better control, but Lambert owns the stronger ERA and WHIP while allowing significantly fewer hits.

Mariners Searching for Answers During Six-Game Slide

Seattle enters Friday having lost six consecutive games and all five of its most recent completed contests. The Mariners dropped two straight against New York by scores of 10-5 and 4-1 after losing three consecutive games against Tampa Bay. Seattle scored only four combined runs during those three losses to the Rays. The Mariners are nine games below .500 overall and have struggled badly away from home with a 23-36 road record.

The Mariners are batting .228 with a .308 on-base percentage and .375 slugging percentage. Seattle has scored 468 runs on 911 hits while producing 141 home runs. The pitching staff has performed considerably better, posting a 3.85 ERA and 1.21 WHIP while opponents are batting .245.

Seattle's pitching gives it a chance to remain competitive, but the offense has been a significant problem. The Mariners trail Houston in batting average, runs, hits, home runs, on-base percentage and slugging percentage. Seattle has scored 91 fewer runs this season, and its recent offensive struggles make those season-long deficiencies even more concerning.

Astros Return Home Atop the AL West

Houston has won two of its last five games and enters Friday following a 2-1 victory at San Francisco. The Astros also earned a 6-3 win in 10 innings during that five-game stretch but lost the other three contests by scores of 4-1, 7-2 and 3-2. Houston sits just above .500 overall at 62-60 and holds a 30-29 record at Daikin Park.

The Astros are batting .243 with a .319 on-base percentage and .411 slugging percentage. Houston has scored 559 runs on 1,000 hits while hitting 162 home runs. The pitching staff has been less reliable, carrying a 4.54 ERA and 1.35 WHIP while holding opposing hitters to a .237 batting average.

Houston's offense is the biggest advantage in this matchup. The Astros have scored 91 more runs than Seattle and have produced 89 more hits and 21 more home runs. The pitching staff has weaker season numbers than Seattle, but Houston enters Friday with the stronger starting pitching statistics and faces a Mariners lineup that has struggled to consistently generate runs.

Seattle Mariners vs Houston Astros Picks and Prediction

Pick: Houston Astros Moneyline

Houston is the preferred side in Friday's AL West matchup. Seattle has dominated the season series at 7-1, but the Mariners enter this meeting on a six-game losing streak and are just 23-36 on the road. Houston possesses the considerably stronger offense and also has the advantage in Friday's starting pitching matchup based on ERA and WHIP. Seattle's season-long pitching numbers keep this matchup competitive, but its offensive struggles and poor road record make Houston the better play at home.

Pick: Under 8.5

With no confirmed total available, take the Under if the total is set at 8.5 or higher. Both starters enter with ERAs below 3.70, and Houston's starter owns a 3.09 ERA and 1.15 WHIP. Seattle has also scored only 10 runs across its last five completed games, while four of Houston's last five have finished with nine combined runs or fewer. Houston's weaker season pitching numbers add some risk, but the starting matchup and Seattle's offensive struggles make the Under attractive at 8.5 or better.
