This probably overstates Mauer's current ability to get on base. He had an obscene 18.9% walk rate in April. It has been 12% since May 1st, exactly in line with his career average. Given how his batting average has stabilized around .270 over the past 3 years, his final 2016 and true talent OBP is probably closer to .350, which would be 27th in the American League right now. Solid, but not necessarily that special. Also, the 2016 AL OBP leaderboard seems to be flukily sparse at the top. Mauer's .370 OBP only ranks 24th in MLB right now. Looking at past seasons, it would have only ranked 13th in the AL at the all-star break in 2015, 12th in 2014, 13th in 2013, etc. Still good, but not quite as good/elite as his "7th in the 2016 AL" rank suggests.
