Marc Pippens Jr, 28, was sentenced to time served to one year in jail, and was immediately paroled.
Pippins also faces a probation violation case in Allegheny County, and will be returned there to face that case.
He was also ordered to pay court costs.
The misdemeanor charge to which he pleaded was later added, and the remaining charge was dismissed as part of the plea.
The charges were filed by the Butler police after a report that Pippens attacked his ex-girlfriend’s father with a baseball bat, causing the 59 year-old Richard Kroll to be hospitalized with a head injury.
