FACTS/FLUKES: L. Castillo, D. Peralta, R. Iglesias, A. Rosario, Wolters

Castillo rebounds … Luis Castillo (RHP, CIN) failed to deliver on lofty expectations in 2018, as he finished the year with a 4.30 ERA in 170 IP, but he did show positive signs in the second half (2.63 ERA in 82 IP). He has carried that momentum into 2019, amassing a 2.56 ERA in 91 IP. Can he keep it up?
