LOS ANGELES -- The Giants announced Wednesday that they've signed 23 players from their 2019 Draft class, including 15 of their first 20 selections.

Arizona State outfielder Hunter Bishop and Louisville first baseman Logan Wyatt, the club's top two picks, are among the players who remain unsigned, though Wyatt is still playing in the College World Series, along with Louisville shortstop Tyler Fitzgerald (fourth round) and Texas Tech right-hander Caleb Kilian (eighth round).

Bishop, who turns 21 next week, was taken with the 10th overall pick, which has a slot value of $4.74 million. The Giants have a pool of $8,714,500 to spend in the first 10 rounds this year, and they've already gone over slot to sign their first three high school selections.

According to MLB Pipeline's Jim Callis, the Giants signed third-rounder Grant McCray for $697,500 (87th overall, $689,300 slot value), fifth-rounder Garrett Frechette for $800,000 (146th overall, $371,600 slot value) and sixth-rounder Dilan Rosario for $650,000 (176th overall, $281,800 slot value).

Ninth-rounder Simon Whiteman, a senior sign out of Yale, agreed to a below-slot deal, signing for $22,500 (266th overall, $155,300 slot value), according to MLB Pipeline's Jonathan Mayo.

Duggar scratched

Center fielder Steven Duggar was scratched from the Giants' starting lineup against the Dodgers on Wednesday with lower back tightness. Mike Yastrzemski replaced Duggar and started in right field, with Kevin Pillar shifting over to center.
