Livo is signed with the Brewers. If not, I would hire Livo just to throw to Harper every day. All the soft breaking stuff, the off-balance unexpected spots, the tailing away stuff that baffles Harper.
Sign him and Jamie Moyer so he has a soft lefty to learn from. Give Harper TONS of simulated games to learn from.
If the team does hold on and makes the playoffs, not the one game win or go home play in, I think Bryce might be a bench bat or defensive replacement with Bernadina taking the majority of starts in CF.
