Reds vs Mariners: Key Matchups and Game Preview
Wednesday's finale pits Brady Singer against Emerson Hancock after the teams split the first two games of the series. Singer is 4-9 with a 4.56 ERA and 1.41 WHIP through 96.2 innings, allowing 105 hits, 31 walks and 21 home runs while recording 82 strikeouts. His trouble limiting hard contact presents a concern against a Seattle lineup with several capable power threats, especially at a park where mistakes can still leave the yard.

Hancock has provided the Mariners with steadier work, going 6-4 with a 3.17 ERA and 1.01 WHIP across 99.1 innings. He has held opponents to 75 hits, issued only 25 walks and recorded 94 strikeouts, giving Seattle a substantial starting-pitching advantage heading into this finale.
De La Cruz Leads Cincinnati's Attack
Cincinnati has hit 132 home runs compared with Seattle's 121, but the Reds are batting only .230 with a .309 on-base percentage and have scored 418 runs. Elly De La Cruz leads Cincinnati with a .280 average, .354 on-base percentage and .509 slugging percentage, while Sal Stewart has supplied a team-high 20 homers and 71 RBI.
