We don’t often see a prospect like De Vries get traded before his 20th birthday, if at all, so it was kind of shocking to see him moved for a reliever, even one as dominant as Mason Miller. Sacramento pushed the switch hitter to Double-A at age 18, where he slashed .281/.359/.551 with five home runs and two stolen bases in 21 games. He even showed plus plate skills: 9.7% walks against 19.4% strikeouts. It’ll be interesting to see how they time this out because he’s got a legitimate case to open the season in Triple-A at 19, an age he’ll stay until October 11th this year. Seems probably we’ll see him in the majors before he turns 20, and that’s a pretty consistent predictor of sustained stardom. Incredible work on the trade market by Sacramento in my opinion.
