Draft Signings: Salazar, Lowry, Turner, Mitchell

With our original draft tracking post becoming just a shade unwieldy, let's start a new list of today's notable second and third-day draft signings. (As before, all recommended bonus slot information is courtesty of Baseball America.)

• Third-round choice Carlos Salazar has agreed to an above-slot deal with the Braves, says Jim Callis of Baseball America (on Twitter). While the precise amount of the bonus is not yet known, Salazar was taken with the 102nd choice, which came with a $505,700 bonus recommendation. A high-school right-hander who has hit 97 with his fastball, Salazar was a consensus top-100 draft prospect. (Baseball America had Salazar at number 93; ESPN's Keith Law put him at 81; and MLB.com's Jonathan Mayo placed him at the 70th slot.) Salazar is being advised by Reynolds Sports Management and Dave Meier.
• The White Sox have signed fifth-round pick Thaddius Lowry for a $400k bonus, Callis tweets. The right-handed Texas high-schooler has flashed upper-mid-90's heat. The Sox went $90.8k above slot to ink the converted catcher.
• Catcher Stuart Turner has signed with the Twins, reports Phil Miller of the Star Tribune. The third-rounder's bonus is not yet known. His draft position (78) comes with a recommended $703k bonus. Turner is regarded as an exceptional defender who delivers lots of contact but does not consistently barrel up the baseball.
• Fourth-round righty Andrew Mitchell of TCU has signed with the White Sox, tweets Callis. According to Callis, Mitchell has one of the draft's most impressive curveballs and has touched 98 on the gun, making him a "steal in the 4th." Mitchell's $413k bonus is exactly slot.
• The Astros have signed fourth-round pick Conrad Gregor, who is advised by CAA, report Brian McTaggart and Jason Mastrodonato of MLB.com. While it is not yet known what bonus the former Vanderbilt first baseman/outfielder is set to receive, the recommended slot for his 107th overall position is $481,900. He is the highest draft choice of the Astros to have signed thus far.
