From Phil Miller's Sunday Insider 6/18: "Xander Bogaerts was a bust. The Aruban infielder, signed by the Red Sox as a 16-year-old in 2009, arrived in the big leagues briefly in 2013, moved into a full-time position in 2014 … and by the end of his rookie season had impatient Boston fans ready to discard him and move on. He flailed at pitches out of the strike zone, couldn’t get on base enough (a .297 on-base percentage) to use his speed, and had problems throwing the ball to first base. Jackie Bradley’s rookie season was a .198 disaster, with 121 strikeouts. Two months after Mookie Betts’ debut, he was batting .228 and hearing that he was “just another Bradley.” No, building with prospects isn’t easy."
