The Toronto Blue Jays are on the verge of making a splash in the international market.
It's the kind of forward-thinking move that can set the Blue Jays up for success many years down the road.
According to Korean baseball insider Daniel Kim, the Blue Jays are "expected to sign" the top high school baseball prospect in Korea.
His name: Seo-jun Moon.
Moon is a senior at Jang-choong High School.
He's listed at 6-foot-5 and is a right-handed pitcher. Moon's fastball is reported to be thrown in the mid-90s.
Kim reports that the signing bonus for Moon is "expected to be more than ($1 million)."
Here's a look at Moon on the mound:

The Blue Jays have had a couple of notable Korean players in their history.
The most prominent was lefty starter Hyun-jin Ryu. he pitched for the Blue Jays from 2020 to 2023 after signing for Toronto as a big-name free agent in 2020.
Before that, the Blue Jays had relief pitcher Seung-hwan Oh on their roster, although he had previously made more of an impact with the St. Louis Cardinals.
It's rare that Korean high schoolers sign at this stage rather than first playing in the KBO, so this is a special opportunity for the Blue Jays to get in on the ground floor of Moon's development. They'll have a chance to grow a pitching star in Toronto.
