Harris has added 2 SPs each winter, so IMO he does so again; 1 established guy, 1 fixer-upper. But, he must get a power reliever (or 2).
Top 13 batters w/no changes: Rogers/Dingler, Tork, Keith, Sweeney/Baez, Jung/Ibanez, Greene/Meadows/Carpenter, Vierling, Malloy.
Shopping list/areas to improve
1B - replace Tork, or have someone who can slide to 1B if he flops again
SS - need to find someone better than Kreidler if you want to replace Baez
3B - Jung's approach is solid, but 0 HRs and iffy D so far
DH - Malloy is crushing LHP but probably not enough to offset defensive limitations
C Walker, W Adames, A Bregman, M Chapman, T O'Neill, A Santander are FAs who would provide real impact.
Christian Encarnacion-Strand (1B/3B/DH) and Oswald Peraza (SS) are some trade targets IMO.
