2 former Reds players who are struggling elsewhere and 1 who's found tremendous success

Former Reds player Luis Castillo is having tremendous success so far in 2023.

The Cincinnati Reds traded Luis Castillo to the Seattle Mariners last summer in exchange for Noelvi Marte, Edwin Arroyo, Levi Stoudt, and Andrew Moore. While the Reds have yet to see much from these young prospects, the Mariners have to be over the moon with their acquisition of Castillo's services.

Castillo has been one of the best pitchers in Major League Baseball this season. La Piedra is 2-0 with a 1.52 ERA in five starters with 34 strikeouts in just under 30 innings of work. A good portion of the Mariners playoff hopes are resting on the right arm of Castillo.

Castillo has just six walks on the season for a measly BB-rate of just 5.4-percent. Couple that with his outstanding 30.4-percent strikeout-rate for a terrific 25-percent K/BB-rate according to FanGraphs. His 25-percent K/BB-rate is the highest of his career.

Do the Reds miss Castillo? No doubt. But at 30 years old entering his final year of arbitration, it was unlikely Cincinnati was going to re-sign their ace. Instead, Castillo inked a multi-year deal with the Mariners and the Redlegs have pinned their future on former first-round pick Hunter Greene.
