I saw somewhere that Sproat had a tale of two halves in AAA last year and it looks like that was true.
First half of his AAA season - .261/.365/.402 opponent slash, 15.6% K-rate, 11.6% BB-rate, 22.5% whiff rate, 88.2 Avg EV, 35.8% hard hit, 5.2% barrel rate
Second half of his AAA season - .165/.254/.248 opponent slash, 30.2% K-rate, 9.1% BB-rate, 29.5% whiff rate, 86.8 Avg EV, 29.9% hard hit, 3.6% barrel rate
