Dylan Crews entered MLB as the No. 2 overall pick in an MLB draft that also included Wyatt Langford, Jacob Wilson, Bryce Eldridge, Kevin McGonigle and several other position players who are currently thriving, or at least treading water.Crews had been an outrageously productive collegiate hitter at LSU, slashing .426/.567/.713 in his final season. He was the Golden Spikes winner, the best hitter on an all-time team. He reached base in every game. His right-handed swing seemed flawless. Crews was immediately a consensus top-10 prospect upon signing with the Nationals.Three years later, Crews has bounced back and forth between the minors and majors, tweaking and retooling and re-retooling his swing. He should have been a lock to make Washington’s opening day roster this year, but he had a scandalously poor spring (3-for-29, 0 XBH, 11 K). Crews instead began the season at Rochester, where he was … well, he was fine, but not spectacular. He produced a .777 OPS with five home runs among his 16 extra-base hits.Crews was elevated to the big-league roster in mid-May, and it’s been a relatively bumpy ride ever since. Recently, however, he’s been as effective as we’ve ever seen him. Crews has four multi-hit games over his past eight, with three doubles and a homer included. He’s still batting just .226 on the season and .214 for his three-year career, so no one is ready to declare him an undeniable must-start player.Still, Crews is still only 24 years old — not yet a finished product. The recent surge could be more than some temporary blip. Over Crews’ first 150 games in the majors, he’s cleared the fence 18 times and swiped 32 bags, so he definitely has the long-term potential to achieve fantasy relevance. Whenever he displays any hint of progress, he’s worth a speculative pickup.
