Julio Pablo Martinez, a 21-year-old center fielder who has been one of the top young players in Cuba, has left the country to pursue a contract with a major league team. At around 5-foot-10, 180 pounds, Martinez is a lefty with a promising combination of power and speed. Last season in Serie Nacional, Cuba's top league, Martinez hit .333/.469/.498 in 264 plate appearances with 52 walks, 30 strikeouts, six home runs and 24 stolen bases in 29 attempts. Based on his present ability, he's probably ready to go to a high Class A or Double-A team. The addition of Martinez to the international signing mix throws an X-factor into the market. To become eligible to sign, Martinez must still establish residency in another country and then wait for Major League Baseball to clear him to sign. Due to his age, he will be subject to the international bonus pools. Based on the recent timetable for other Cuban signings, Martinez shouldn't have a problem getting cleared to sign during the current 2017-18 signing period, which opened on July 2 and closes next year on June 15. However, unlike when Luis Robert left Cuba and signed with the White Sox for $26 million earlier this year, Martinez is in a tricky spot. Not only do teams now have hard caps on their international bonus pools, but many of them have already spent either most if not nearly all of their current 2017-18 bonus pools. For those that have more pool space remaining for this signing period, such as the Yankees and Rangers, their plan A is to spend that money on Japanese two-way star Shohei Ohtani if he becomes available this offseason through the posting system. Teams are allowed to trade for up to an additional 75 percent of their original pool allocation, so teams with a $4.75 million pool can trade for up to a little more than $8.3 million, while teams with the highest pools at $5.75 million could trade for up to a tick above $10 million.
