Red Sox star Chris Sale lost his mind following a rocky rehab start Wednesday night ... destroying items and completely trashing a runway in his team's dugout.
The meltdown was all captured on video following the ace's short outing with Boston's Triple-A affiliate, the Worcester Red Sox.
In the short clip, you can see the 33-year-old pitcher -- who was throwing for the WooSox in another effort to make it back to the Big Leagues from a rib injury -- ripping items off the wall and kicking them violently.
