Additionally, Halladay also had the sedative zolpidem - commonly sold under the brand name Ambien - in his body at the time of the crash, TMZ reports, citing a report released by the Pinellas-Pasco Medical Examiner's Office.
Halladay spent the final four seasons of his eventual 16-year Hall-of-Fame career with the Phillies.
The remains of an ICON A5 ultralight airplane are moved from a boat ramp in the Gulf Harbors neighborhood of New Port Richey, Fla., on November 8, 2017. Video from around the time of the incident shows the plane flying a couple hundred feet in the air before dropping toward the water.
His blood-alcohol level at the time of the crash was 0.01, according to the Tampa Bay Times. The tests also came back positive for amphetamines.
TMZ reported that a source close to the autopsy said,"The results are consistent with someone who uses Rx [prescription] medication". One thing of note ... the FDA lists on its website that more than 50 ng/ml of zolpidem "appears capable of impairing driving to a degree that increases the risk of a motor vehicle accident". Halladay was reportedly found to have 72 ng/ml of zolpidem in his system.
Just how much of those items was in Halladay's system was not revealed, although it was stated that he had a blood-alcohol content of.01.
Halladay was among the top baseball players of his generation, twice winning the Cy Young Award given to the MLBs best pitchers each year. He won the 2010 National League Cy Young Award and pitched a flawless game while winning 21 games in his first season with the Phillies.
