Fun with small sample sizes... Murphy's 2015 line with .357 BABIP: .277/.327/.406, .734 OPS, 103 OPS+, 99 wRC+ adjusted to his career minor league BABIP (.296): .232/.287/.361, .648 OPS, ~78 OPS+, ~74 wRC+ with his career minor league BABIP, plus his most recent AAA K%: .245/.298/.374, .672 OPS, ~87 OPS, ~83 wRC+ (His AAA ISO was a little higher too, but I did not adjust his MLB ISO for simplicity since it was already respectable, he's moving to Target Field, and he's a right-handed non-pull hitter. Similarly his most recent AAA BB% was already close too.) League average for catchers in 2015 was 89 OPS+, 85 wRC+ So based on this back-of-the-envelope estimation, to get him to positional league average, we're probably going to have to cut his strikeouts. Are the Twins the team to do that? We don't have a great track record in that department... Hicks did it in 2015 but was already noted for his pitch selectivity... will be interesting to see. EDIT: corrected adjustment for most recent AAA K%
