The Cardinals were aggressive in trying to sign Cuban outfield prospect Luis Robert, but general manager John Mozeliak sensed the 19-year-old would end up elsewhere, writes Jenifer Langosch of MLB.com. Robert proved Mozeliak correct when he agreed to sign with the White Sox on Saturday. Ultimately, St. Louis wasn’t up to paying north of $50 million, including a 100 percent overage tax, for Robert. “When you’re looking at the overall investment, it’s real and historically there are not too many players that sign for that many dollars,” said Mozeliak. “It’s really hard to justify those types of dollars for any player with a lack of a proven track record. No matter how you try to equate the Cuban league or his international experience, it’s very hard to calibrate what that means to here.”
