Last season was a monumental one for the Mariners. They captured their first AL West division title since 2001 and advanced to the ALCS, where they lost to the Toronto Blue Jays. Seattle looks to build on that progress and end its World Series drought. The Mariners are the only MLB franchise that hasn't made a World Series.
The Padres, whose last World Series appearance was in 1998, are also in search of their first World Series title.
San Diego finished the regular season 90-72, winning at least 90 games in consecutive seasons for the first time in franchise history. They were eliminated by the Cubs in the NL Wild Card series.
2007 NL Cy Young Award Jake Peavy and former Major League pitcher Ryan Rowland-Smith will join play-by-play voice Jason Benetti in the booth for this week’s Sunday Night Baseball broadcast. Ahmed Fareed will host the pregame show alongside Anthony Rizzo, who will also provide “Inside the Pitch” commentary from the batter’s perspective during the game.
