Taillon and Allie will each be introduced with a press conference at PNC Park before the end of the week. Those press conferences are expected to take place on two different days.
It is customary for the Pirates to bring in their top Draft pick to talk with the media shortly after signing. Taillon, who reportedly received a $6.5 million signing bonus, will be flying in from Texas.
Allie, who can make the drive from his Cleveland-area residence, is more notable than most second-round picks given his pedigree and signing bonus. With an agreement worth $2.25 million, Allie received money recommended for a top-10 pick.
"To get two guys alike in your system -- two of the top high school pitching prospects in the country -- is phenomenal," manager John Russell said the day after both signings were announced. "We said coming in that to get to the point where we need to be as an organization, the Draft was going to be very important.
"I'm very proud of the work they've done upstairs to get these guys in our system. I can't wait to see them. It's going to be exciting times for us."
