Second-round pick Sam Carlson, a right-hander from nearby Burnsville, Minn., stood on the field Tuesday and watched the Mariners take batting practice prior to their game against the Minnesota Twins at Target Field.
"He did the tour," scouting director Scott Hunter confirmed. "He’s meeting with some of the staff there, and we’re pretty confident this week that, once his high school season is over, he'll be in a Mariners uniform."
Signing Carlson, 18, would represent something of a coup for the Mariners. He ranked as the No. 15 prospect in the MLB.com pre-draft rankings and No. 21 in the Baseball America Top 500. That’s roughly a mid-first round pick.
The Mariners took him at No. 55 overall.
Carlson remained available, at least in part, because of signability concerns. He has a scholarship offer to Florida and didn’t figure to come cheap.
The 55th pick has a slot value of $1,206,900, which means the Mariners must find another $1 million or more in their bonus pool just to boost their offer into the slot range of a late first-round pick.
Doing so would require them to get several picks in the first 10 rounds to agree to sign below slot value.
Some background: Major League Baseball assigns a slot value to every pick through the first 10 rounds. A club’s bonus pool is the combined value of its picks.
There is no restriction in the spending on any specific pick — clubs can exceed the pool on some picks and sign others for below slot value — but penalties are assessed if a club exceeds its bonus pool.
"You play the system," one club official said. "Everyone does."
The Mariners began playing the system Tuesday, once the draft resumed, by selecting Gonzaga sidearming reliever Wyatt Mills, a senior right-hander, in the third round.
First note this: Mills, 22, posted impressive numbers for the Zags: a 1.79 ERA in 22 appearances while striking out 58 and walking just four in 40 1/3 innings. Hunter likened him to Joe Smith and Steve Cishek.
"Every time I’d watch the kid’s video," Hunter said, "it just reminded me of that. It’s a unique arm slot…He's the type of guy who you get into the system, there’s not much more he can do but go out and keep performing.
"He could be a quick mover if he keeps doing the things he’s doing right now."
Even so, Mills seems a reach with the 93rd overall pick, which carries a slot value of $579,800. He wasn’t in the MLB.com Top 200 or even in the Baseball America’s Top 500.
It didn’t stop there.
Of the Mariners’ eight selections on Tuesday, Mills was one of four not ranked among Baseball America’s top 500 prospects. Two others were ranked more than 100 slots below where the Mariners selected them.
Not that those rankings are infallible, but even Hunter acknowledged, "We were in a situation with Sam Carlson where we had to look for opportunities to balance our bonus pool and get the most out of it."
Only one of Tuesday’s eight picks, catcher David Banuelos, a fifth-round pick from Long Beach State, ranked significantly higher in the Baseball America rankings than his selection.
Sixth-round pick Oliver Jaskie, a lefty from Michigan, was within one slot of his Baseball America ranking.
The draft consists of 40 rounds over three days. The first two rounds and the two competitive-balance rounds took place Monday; rounds three through 10 were Tuesday; and 11 through 40 are Wednesday.
The Mariners selected Kentucky first baseman Evan White on Monday with the 17th overall pick before choosing Collier in the second round.
Drafted players must sign by July 15. Those who don’t sign and attend a four-year college are ineligible to be drafted again until after their junior year. Those who don't attend a four-year college can be drafted again in 2018.
One catch: If a player doesn’t sign, his slot value is subtracted from a club’s overall bonus pool. So, no, a club can’t spent its entire pool on two or three players and allow the others to go unsigned.
