"I think it's a very exciting opportunity for both," Cardinals general manager John Mozeliak said on Monday. "I think this is a great experience for these guys. You hope when competing that no one gets hurt, and that, in the end, it grows the game globally. For me, I don't have any concerns going into it. And as long as the player is excited about the opportunity, it's great."
The only player on the Cardinals' 40-man roster to previously be confirmed as a participant is catcher Yadier Molina, who will be representing Puerto Rico in the Classic for a fourth time. There still may be more. This year's tournament will be held from March 6-22, meaning that participating players will be absent from Spring Training for some length of time.
That's not so much a concern for Martinez, who has established himself as a key member of the Cardinals' rotation. It may be a bit more significant for Reyes, who isn't assured of a starting job out of camp. He is, however, expected to enter Spring Training as a favorite to snag one of the remaining rotation spots.
Reyes, 22, appeared in 12 games and logged 46 innings after being called up by the Cardinals in August. He posted a 1.57 ERA and helped lead the Cardinals to wins in three late-season starts after being thrust into the rotation. He is ranked by MLB Pipeline as the organization's top prospect and the seventh-best prospect in baseball.
Martinez threw a career-high 195 1/3 innings as he emerged an ace of the Cardinals' staff in 2016. The 25-year-old led all Cardinals starters with 16 wins, a 3.04 ERA and 174 strikeouts.
