"context_description": "In the series finale at pitcher-friendly T-Mobile Park, the Cleveland Guardians hold a 2-1 edge over the Seattle Mariners after Saturday's 6-5 extra-inning thriller, where Chase DeLauter's home run streak proved decisive in a Guardians rally. Probable starters are Guardians RHP Slade Cecconi, fresh off a strong spring with a sub-2.00 ERA, against Mariners RHP Emerson Hancock, who carries a 5.40 ERA early. Key absences include Mariners SS J.P. Crawford (10-day IL, shoulder soreness) weakening infield defense, while Guardians SP Tanner Bibee remains day-to-day with shoulder inflammation but threw a recent bullpen. Taxed bullpens from back-to-back close contests add uncertainty to this Sunday Night Baseball matchup.",
