If parsing semantics, then I base my opinion looking at several statistics -- not just OPS+ (which combines OBP and Slug).
Abreu had the most home run pop, with 22 HRs in 51 less games than Rafaela, who hit 16. And yet, Ceddanne only struckout 16 more times in 170 more at bats...
He also had twice as many doubles, 4 triples to 0, and 20 stolen bases to 4 for Abreu.
Runners-in-scoring position: Abreu .262 BA, .895 OPS; Rafaela .242, .670
High leverage: Abreu .226, .774; Rafaela .281, .808
Batting average: Rafaela hit .249, Abreu .247.
Outta slight, man
