Hayes is the son of Charlie Hayes, a third baseman who spent 14 years in the Majors and played for the Pirates in 1996.
• 19th overall: Kevin Newman
• 62nd overall: Kevin Kramer
With Hayes, it was clear to the Pirates that his heritage has impacted his ability on the field.
"I think we look at the individual. In Ke'Bryan's case, he does exhibit a very good feel for the game," scouting director Joe DelliCarri said. "The way he operates within the game, how he sees the game. So I would say in his case, Ke'Bryan did show consistently that feel, instincts for the game.
"Just because they would have bloodlines, I'm not necessarily sure it's there all the time. But clearly in this case with Ke'Bryan, it's showing on both sides of the ball. His feel and understanding and play within the game, his control of the game, his ability to slow things down on both sides of the ball were strong."

The 32nd pick's value was slotted at $1,855,000. Hayes was ranked by MLBPipeline.com as the Draft's No. 44 overall prospect.
The selection of Hayes after University of Arizona shortstop Kevin Newman, the 19th overall pick, continues an obvious trend for the Pirates, who have now selected position players with their first two picks in each of the last three years.
The 6-foot-1, 207-pound Hayes is regarded as an advanced high school hitter, as he closely resembles his father, who was a fourth-round pick by the Giants in 1983.
Hayes hit .436 (41-for-94) with 16 doubles, one triple, three home runs, 27 RBIs and 12 stolen bases during his senior season.
"As a corner bat, we like his upside and we like his overall package as well," Pirates general manager Neal Huntington said.
Hayes has committed to the University of Tennessee, but he's considered one of the more signable high school prospects in this year's Draft class.
And Hayes seems prepared to follow in his father's footsteps, as he expressed his gratitude towards Pirates for making his "dreams come true" in a message from his Twitter account Monday night.
