The Indians were drawn to Papi's blend of power and patience in the batter's box.
"He does have that advanced feel to hit," Brad Grant, the Indians' director of amateur scouting, said after drafting Papi. "He is extremely patient at the plate. He doesn't expand the strike zone. He has a natural ability to hit the ball and he has the ability to move around the field.
"He can play left, he can play right, he can play first. He brings you a lot of versatility in terms of defense to his game. And, there's power that can develop."
Also on Thursday, the Indians signed both right-hander Micah Miniard (eighth round) and catcher Juan Gomes (37th round). Miniard signed for a bonus of $350,000, which was more than the suggested slot value of $155,800. Gomes -- the younger brother of Cleveland catcher Yan Gomes -- signed a Minor League contract for 2015.
MLB.com's Jim Callis confirmed that Papi received a signing bonus worth $1.25 million, which is below the suggest slot value ($1,495,400) for the 38th pick this year. With Papi signed, Cleveland has reached deals with 29 of its 42 selections, including the team's first 15 picks (covering the first 13 rounds).
This past season with Virginia -- the national runner-up to Vanderbilt -- Papi hit .307 with 11 home runs, 11 doubles, 55 runs and 56 RBIs in 69 games. He posted a .451 on-base percentage and also finished with more walks (61) than strikeouts (46) for the Cavaliers.
International signings: The Indians have signed a pair of international prospects to professional contracts. MLB.com's Jesse Sanchez confirmed that Cleveland inked Dominican right-hander Leonardo Rodriguez to a $300,000 deal. According to a tweet from the Dominican Prospect League, the Indians also signed shortstop Oscar Gonzalez to a $300,000 pact.
