Former MLB star Delmon Young -- the MVP of the 2012 ALCS -- was arrested Monday ... after his ex-girlfriend alleged he punched in her the chest and shoved her to the ground.
Officers at the Davie Police Dept. in Florida, according to docs obtained by TMZ Sports, say the incident all went down at around 11:44 p.m. on Monday night.
Cops in the docs say a woman claiming to be Young's ex-GF said the former baseball player showed up to her home and began banging on her door and ordering her to come outside.
