Wilson receives a $5.5 million signing bonus, which is roughly $1.1 million less than slot-value for the sixth overall pick. The son of former All-Star shortstop Jack Wilson batted .412 and struck out only five times in 49 games this spring for Grand Canyon in his final collegiate campaign.

This qualifies as a bit of a surprise, but the rebuilding Athletics will roll the dice on the son of longtime Pirates shortstop Jack Wilson. Jacob has taken after his father in becoming a fine defensive shortstop, and he just posted a stellar .412/.461/.635 triple-slash line, while striking out only five times all season for Grand Canyon. The 21-year-old middle infielder never figures to hit for much power, and also doesn’t offer a lot of speed, so he’s not especially interesting as a fantasy prospect. However, the top-notch contact ability, combined with his defense, could make him a quality regular at the big-league level.

The move frees up a spot on the 40-man roster. Wilson is 3-for-20 at the plate this season for the A's and Astros.

This move clears out a 26-man roster spot for Alex Bregman, who is back from the IL on Wednesday. Wilson has slashed just .150/.190/.300 in 21 plate appearances this year between Oakland and Houston.
