Clayton Kershaw had easily baseball's most adorable offseason workout plan

Last winter, the world got a rare glimpse into the offseason preparation that makes Clayton Kershaw arguably the best pitcher in baseball: his young daughter and daunting personal trainer Cali.

We're certainly not saying that Cali was totally responsible for her dad's success. We're just saying that, under Cali's watchful eye, all the lefty did was post a league-leading 1.69 ERA and 172 strikeouts in 148 innings. Coincidence or not, Kershaw isn't taking any chances -- so, this winter, he's been hunkered down with Cali again, and the two seem to have moved on to some advanced yoga.

No word yet on whether Brandon McCarthy has any concerns.
