Diamondbacks vs. Athletics updates. A $5.24 million bonus for top pick

The Diamondbacks have signed 20 of their 21 picks, including all 11 players they took in the first 10 rounds of the baseball draft held earlier this month.

>Top selection Ryder Helfrick, a catcher out of Arkansas, received a signing bonus of $5.24 million, the full slot value for his pick at No. 15 overall.

>Georgia Tech infielder Carson Kerce, the club’s second-round pick, got $1.9 million, a tick above slot ($1.85 million) for No. 53 overall.

>Right-hander Mason Steele, the club’s 10th-round selection out of Alabama-Birmingham, also signed for full slot.

>Beyond that, the Diamondbacks saved money on the rest of their selections in the top 10 rounds.

>That allowed them to redirect some of the savings toward 11th-round pick Cody Boshell, a left-handed-hitting first baseman out of a Florida high school with significant power projection. Boshell signed for $750,000.

>The only unsigned player is 17th-round pick Rylan Alaniz, a prep shortstop from Texas, whom the Diamondbacks are still hoping to sign away from a Texas State commitment.
