Pirates outfielder Gorkys Hernandez was called upon to pinch run in the top of the 14th inning in Detroit Tuesday and, well, the substitution didn't exactly go as planned.

Josh Harrison ripped a double in the gap -- despite the best efforts of Tigers center fielder Rajai Davis -- and Hernandez distinguished himself in a bad way. Take a look.

OK, so let's sort this out. First of all, if you know enough to retouch second base on your way back to first, you definitely should know to retouch second again on your way to third.

Next up, it's a double in the gap! Hernandez should have scored the go-ahead run. Instead, he was confused and then totally botched his job as a pinch runner. Such confusion could be at least relatively excused thanks to the ball being a bit hidden as it rolled around, of course, but it still feels pretty ugly here.

Finally, it was pretty awesome to see what remained of the Detroit crowd being so vocal about the appeal. Good work, Tigers fans.

All is well that ends well, I guess, because Neil Walker would double home Harrison and the Pirates would win. That gets Hernandez off the hook to some extent, but this is going to go down as one of the more memorable baserunning blunders in recent memory -- from a pinch-runner, no less.
