To me, Hanser Alberto was a relatively successful pickup. 3.4 rWAR in what amounts to 1.4 seasons, compared to Núñez’s 2.2 rWAR in 1.8 seasons. Yeah Nunez has the better bat but Alberto’s overall package is better IMO since he has some defensive value.
For that matter, Alberto’s 3.4 rWAR the last two seasons is more than Santander’s 2.9, though I’d certainly say the trend favors Santander being the better player over the next several years. I’m looking forward to seeing if Santander can sustain the progress he’s shown the last two years.
