Why does Chase Burns matter in this matchup?
According to Lookout Landing, Seattle faces an exceptional Chase Burns start while short-handed. Burns signed a seven-year, $105 million deal last week and is described as very good with only two pitches.
Yahoo Sports frames Burns as Cincinnati’s burgeoning new ace, a right-handed fireballer aiming to prove he belongs in that role. His extension roughly echoes the $108 million commitment Castillo later received from Seattle after leaving the Reds.

What history links Castillo to this Reds lineup?
Castillo, a former Reds ace and All-Star, starts against the club that traded him to Seattle in 2022. Yahoo Sports notes that Noelvi Marte and Edwin Arroyo—the headliners Cincinnati received in that deal—are both in the lineup to face him.
Spencer Steer is getting a break after a bean-ball to the ribs the night before. Yahoo also says the Reds “gave” Seattle Monday’s game in epic-fail fashion and are expected sellers at the trade deadline in two weeks.
How are the Game 102 lineups set?
Yahoo Sports lists Cincinnati as Elly De La Cruz, Sal Stewart, JJ Bleday, Eugenio Suárez, Nathaniel Lowe, Noelvi Marte, Jose Trevino, TJ Friedl, and Edwin Arroyo, with Chase Burns on the mound.
Seattle’s posted order is Cole Young, Randy Arozarena, Dominic Canzone, Cal Raleigh, Josh Naylor, Luke Raley, Victor Robles, Colt Emerson, and Weston Wilson, with Luis Castillo starting. Lookout Landing says the Mariners will take that shortened group into a tough assignment against Burns.
The series continues at T-Mobile Park, where Seattle will try to turn a heat-check stretch into a four-game winning streak against a Reds club still searching for deeper October relevance.
