DeJong, who was taken with the 52nd overall selection in the First-Year Player Draft, reportedly signed for $820,000 according to a report by Baseball America.
The 6-foot-4, 185-pound right-hander posted a 1.80 ERA and 240 strikeouts over 199 innings in three seasons for Woodrow Wilson High School in Long Beach, Calif. His older cousin, Jordan, is a former reliever for the Blue Jays.
The only Blue Jays draftee taken in the first 10 rounds who has yet to sign a contract is first-rounder Marcus Stroman. The product of Duke seems relatively optimistic of reaching a deal in the near future as he tweeted on Friday that he has "some news for y'all soon!"
Toronto has just over $2.1 million remaining in its total Draft cap -- including fines. Anything over that total would result in the loss of a future pick, which is a penalty the club is not inclined to pay.
The recommended slot value for Stroman (No. 22 overall) is $1.8 million. He is expected to receive slightly more than that.
