Coby Mayo hit a three-run homer Thursday off the Cardinals’ Caleb Ferguson.

The homer was Mayo’s 14th off a left-hander, which ties him with Matt Olson for first in the majors. He’s also first with an 1.109 OPS against southpaws (min. 100 PA), with Andrew Vaughn second at 1.041. And the homer today was projected at 446 feet, making him one of just eight players this year to exceed 440 feet four or more times (Junior Caminero and Kyle Schwarber are tops at six times apiece). Unfortunately, Mayo is still at a pretty horrible .199/.227/.272 in 225 plate appearances against righties this year, leaving his future as a regular rather murky. The power spike would be more promising if it wasn’t coming with a 32.5 percent strikeout rate. He finished at 28.6 percent as a rookie last year.
