I don't doubt you one bit, but I'm familiar with clutch scores. I was just looking at wRC+ with the bases empty, men on base and men in scoring position. He's been consistently better with MOB and MISP since 2016.
2019: Empty - 82, MOB - 176, MISP - 187
2018: Empty - 112, MOB - 165, MISP - 143
2017: Empty - 141, MOB - 171, MISP - 154
2016: Empty - 99, MOB - 124, MISP - 127
2015: Empty - 199, MOB - 195, MISP - 163
2014 was pretty ugly with MOB, MISP....maybe he practiced a lot to be better at this 'skill'
