| Player | Hits | Strikeouts |

When building your lineups, the pitching duel in Cincinnati offers compelling angles. Spencer Strider brings a dominant 11.07 K/9 rate to the mound. Conversely, Nick Lodolo enters tonight with a 7.71 K/9 and faces a deeply talented Braves lineup.
At the plate, Elly De La Cruz remains a spark plug for the Reds, batting .274 with 63 hits over 230 at-bats. On the other side, Ronald Acuña Jr. is carrying a .246 average, but Lodolo’s 1.38 WHIP indicates plenty of expected traffic on the basepaths.
