"context_description": "Houston Astros face Seattle Mariners at T-Mobile Park in an AL West matchup, with Astros' pitching depth severely tested by early-season injuries to starters Cristian Javier (shoulder) and Hunter Brown (shoulder strain), plus closer Josh Hader (biceps tendinitis), forcing spot starter Cody Bolton (3.68 ERA) against Mariners' Logan Gilbert (0-2, 5.40 ERA, strong 3.33 career mark vs. Houston). Astros skid with six losses in seven games, including a 9-6 defeat Friday, hampered by 7.17 ERA over last 10 outings and 1-6 road record, despite potent .289 AVG recently. Mariners boast 3.57 ERA lately and home edge (4-4), though hitters scuffle at .181 AVG last 10; both clubs hover around 6-8 in tight division standings.",
