Tucker was the second-youngest player and third-best hitter (155 wRC+) in the Pacific Coast League. He had three short stints in the big leagues (MLB debut on July 7) but never got going at the dish. In the 28 Triple-A games (including PCL playoffs) that followed his MLB debut, he hit .388/.463/.750 with 12 home runs and eight steals, so it is safe to say he has nothing to prove at that level. Tucker has plus power and should have no trouble hitting 20-plus homers once he is playing every day. His stolen-base totals oversell his pure speed, but he has good instincts on the bases and should be a double-digit contributor there as well. His batted-ball profile at Triple-A was ideal (35.8 GB%), and while he may not be a .300 hitter, he will do a lot of damage as a .270 or .280 hitter. To manipulate his service time to maximize their years of control, the Astros would need to hold Tucker down until mid-May, which would be disingenuous, but also can't be ruled out.

Reasonable minds could disagree about whether power, speed or batting average will be Tucker's most valuable fantasy contribution, and that's the selling point. He's good at everything. In 2016 he stole 32 bases on 44 tries. He only stole 21 bags last year, but launched 25 homers across stops at High-A and Double-A, putting an end to the "will he hit for power" debate. A .286 BABIP suppressed his Texas League batting average, but his hit tool has the potential to be special -- his swing receives Ted Williams comps. Tucker has been unduly pull happy (49.1 percent pull rate at Double-A) for a prospect with the raw talent to compete for batting titles. His newfound over-the-fence power may have momentarily compromised his approach, but with more upper-level instruction, he should eventually display an all-fields approach. He is the Astros' best hitting prospect since Alex Bregman and capable of playing all three outfield spots, so while the big-league roster is crowded, the velvet rope will be lifted when he's ready to join the mix this summer.

Drafted fifth overall in 2015, Tucker spent much of last season with Low-A Quad Cities but reached the High-A level for the final 16 games of his age-19 campaign. The brother of Preston Tucker (also in the Astros organization), Kyle didn't miss a beat following the promotion. In fact, he surged at the dish, going 20-for-59 (.339 average) with 11 extra-base hits and a 10:6 BB:K with Lancaster. Not only does Tucker demonstrate an advanced approach and discerning eye for his age, he has plus speed and there's plenty of room for power growth as he fills out his 6-foot-4 frame. He is already a top-20 prospect for fantasy purposes and he has the skill set to rise quickly through the system, so Tucker should be treated as a hot commodity in any long-term keeper league with minor league roster spots.

Tucker, the fifth overall pick of the 2015 draft, joined the same organization as his older brother Preston when the Astros selected him last June. One of the top hitting prospects in the 2015 class, the 6-foot-4, 190-pound outfielder struggled in rookie ball, hitting only .246/.294/.353 in 63 games between the Gulf Coast League and Greeneville Astros. He did help Greeneville win the Appalachian League title, however, alongside 37th overall pick Daz Cameron.
