The ex-MLB star surrendered to authorities in San Diego on Friday to begin his 3-year prison sentence in his cocaine case -- and after his sentence, he's expected to be deported to Mexico.
As we previously reported, Loaiza -- who made more than $40 MILLION during his 14-year MLB career -- was arrested last year after cops say he was trying to move 44 pounds of cocaine from a house located near a school..
Cops say the coke stash is worth more than $500,000!!!
The 47-year-old was quiet and stone-faced as he walked into the federal courthouse on Friday -- not saying a word to the waiting media.
