Overview

• Fernando Tatís Jr., back after an illness, launched a fourth-inning grand slam to lead San Diego to a 7-4 win at Petco Park.
• The defeat, combined with a Reds victory and tiebreakers, mathematically knocked Arizona out of playoff contention with two games remaining.
• The Padres have clinched a wild-card matchup with the Cubs but remain two games back for home field and must sweep while Chicago loses twice to host the series.
• Yu Darvish covered five innings for the win and Mason Miller recorded a four-out save; Luis Arraez had four hits to push his hitting streak to 14 games.
• Roster notes shaping the series: San Diego's Ramón Laureano fractured his right index finger and is out through the wild-card round; Chicago says Cade Horton is available despite MRI 'areas of concern'; Arizona’s Zac Gallen was tagged for six runs in a start that could precede his free agency.
