SEATTLE — The Mets will hope both their Day One draft picks were worth the waits.

Their first they had to wait 10 extra selections to make, and their second they waited for a full year to sign.

The Mets — whose first pick was pushed out of the first round because of last year’s high payroll — selected Colin Houck, a high school infielder who fell to No. 32 overall at the First-Year Player Draft at Lumen Field on Sunday.

They followed it up in the second round by grabbing righty Brandon Sproat, a University of Florida pitcher whom they failed to sign as a third-round pick last year.

First came Houck, a 6-foot-2 shortstop from Parkview High School in Georgia.

The Mets plucked from Braves territory in selecting the 18-year-old, who will have to be cajoled out of a commitment to Mississippi State.

“I did grow up a Braves fan,” Houck said on a Zoom news conference. “But with the Mets picking me, that’s obviously not the case anymore.”

Houck was rated the 12th-best prospect overall by MLB Pipeline after he hit .487 with eight home runs and 16 stolen bases in his senior season.

The fact that he was still available came as pleasant news to the Mets.

“I would say we were surprised that he got down there to us,” said Drew Toussaint, the director of amateur scouting, “but super excited that he did.”

Houck was Gatorade’s Georgia Player of the Year in baseball but impressed in football, too, as three-star quarterback recruit.

Houck is an athlete who is well-regarded, particularly for a powerful swing, and is coming out of a high school that has seen some athletes.

Braves first baseman Matt Olson is a Parkview alum.

In the second round, the Mets picked Sproat for a second time.

Last year, they picked the righty 90th overall but did not come to an agreement for a contract.

Sproat returned to Florida, pitched to a 4.66 ERA with 134 strikeouts in 106 ¹/₃ innings, and this time went No. 56 to the Mets.

“Funny how the world works,” said Sproat, who declined to go into detail concerning why he did not sign last year, though he did have to consent to the Mets selecting him again this year. “Went back, bet on myself, and it was for the better.”

Sproat was selected higher, but likely will not receive the payday he was hoping for as a senior who cannot return to Florida.

“High 90s fastball touching 100, ability to spin the baseball,” Toussaint said. “We’re excited for him.”

The Mets were one of two teams, along with the Dodgers, that did not have a true first-round selection this year. Both clubs’ first picks moved back 10 spots because they went over the luxury-tax threshold by more than $40 million last season.

Houck will join a system that is deep with shortstops, who are particularly valuable because they typically can make transitions to other positions.

Francisco Lindor is entrenched as the big-league shortstop, while No. 2 prospect Ronny Mauricio has begun playing second base and left field at Triple-A Syracuse.

Jett Williams, the Mets’ No. 3 prospect and a first-round pick last year, has predominantly played shortstop at Class-A St. Lucie.

In choosing Houck, the Mets showed a further propensity for high-school position players.

They had selected high-school hitters — Jarred Kelenic (2018), Brett Baty (2019), Pete Crow-Armstrong (2020) and Williams (2022) — with four of their past six first-round picks.

The exceptions were catcher Kevin Parada, from Georgia Tech, last year, and Vanderbilt pitcher Kumar Rocker, whom they did not sign in 2021.

The Mets did not select for a first time until 32nd, but they have seven picks within the first 135 selections. They accumulated three compensation picks from losing Sproat last year and Jacob deGrom and Chris Bassitt (who were given qualifying offers last year and signed elsewhere in free agency) last offseason.
