Luis Castillo has changed his pitch mix early in 2019, resulting in a surging strikeout rate in CIN. Also: a fresh look at the outfield situation in STL and PIT, reinforcements in the CHC bullpen, and the heavy dose of fastball MIL batters continue to see.

Kyle Schwarber is returning to an old swing in CHC. Also: the closer situation in MIL, another catching prospect blocked in STL, the final rotation spot in PIT, and Senzel's permanent home in CIN.

Some young, promising pitchers got pushed out of the rotation in CIN, but they shouldn't be forgotten. Also: playing time at the hot corner in PIT, back-of-rotation starters in STL, the impact of Moustakas's return in MIL, and David Bote's playing time in CHC.
