The Mariners made their presence felt on Sunday, the first day of the international signing period, by coming to terms with two of the top prospects on the market.
Sources indicated the club agreed to a $1.75 million deal with Dominican Republic outfielder Julio Rodriguez, ranked No. 9 on MLBPipeline.com's Top 30 International Prospects list, and a pact with Venezuela shortstop Juan Querecuto, ranked No. 26, for $1.225 million.

The club did not confirm the deals.
Rodriguez is expected to hit for average, and he already shows good raw power. Overall, the teenager has the ability to drive the ball to all fields and he consistently makes hard contact. He has the potential to be a middle-of-the-order type of run producer in the future. On defense, Rodriguez profiles as an everyday right fielder because of his solid defensive skills and plus-arm potential.
As for Querecuto, he's a confident prospect with good plate discipline and good instincts on both sides of the ball. The teen has showed good bat speed and the ability to hit the ball to all fields. On defense, he displays a strong arm -- more than enough to keep him at the shortstop position -- and good defensive actions in the field.
The son of Minor League catcher Juan Querecuto and younger brother of Juniel Querecuto, who reached the Majors with the Rays in 2016, the young infielder grew up around the game.
According to the new rules established by the new Collective Bargaining Agreement, every team gets at least $4.75 million to spend on international prospects. Any team receiving a Competitive Balance Round A pick in the Draft gets $5.25 million in international bonus pool money. Additionally, teams receiving a Competitive Balance Round B pick get $5.75 million to spend.
A club can trade as much of its international pool money as it would like, but there is a limit -- 75 percent of a team's initial pool -- to how much one team can acquire.
The Mariners' pool total for this year's signing period is $4.75 million.
