Josh Naylor

Naylor broke summer camp with the Padres, but he played sparingly and almost exclusively against right-handers. He was sent to the alternate site for 10 days in August before returning. Naylor was slashing .278/.316/.417 when he was dealt to Cleveland on Aug. 31. He played more with Cleveland, but still only against righties, slashing just .230/.277/.279. While it's encouraging Naylor's season-long contact rate was 86.4%, it was mostly weak and on the ground, not conducive for a 70 raw power grade. Naylor's average exit velocity on flyballs was well below average, again not good for homers. Naylor is another case in which it's better to trust the reports and results prior to 2020 over a two-month sample in trying conditions. Cleveland's outfield is in flux, though Naylor should be given a shot at the busier side of a platoon.

Naylor made his debut May 24 and was up and down a few times before settling in for good after the deadline. Some scouts have put a 70 on Naylor's raw power, but he's still working to get to that in games. His ISO with the major-league team was .154, so about league average. He walked at a useful clip but his strikeout rate nearly doubled with the jump from Triple-A to the majors, and in total, Naylor graded out as 11% worse than league average by wRC+. As expected, the lumbering Naylor was a negative on defense, and he was below replacement level by fWAR in his 279 plate appearances. The body is a problem -- he was listed at 5-foot-11, 250 pounds at age 21 -- and that figures to only get worse with age. San Diego would like to trade Wil Myers, but that seems unlikely. There will only be room for two starters between Trent Grisham, Myers and Naylor, with Tommy Pham in the same outfield.

The biggest development for Naylor in 2018 was that most of his starts came in left field. He had previously only played first base. His stats through 170 career games at Double-A (.286/.368/.423, 19 HR, 14.0 K%, 10.7 BB%) are solid for a player who won't turn 22 until June. However, the fact he won't be a good defender anywhere, particularly in the outfield, means he will have to do a ton of damage at the plate to get playing time in the National League. The 70-grade raw power that led to him getting selected in the first round in 2015 has not consistently shown up in games, but he has been a better pure hitter than originally anticipated. Eric Hosmer signed an eight-year deal last offseason and the Padres already have a couple bat-first, below-average defenders competing for time in the outfield corners (Franmil Reyes and Hunter Renfroe), so Naylor feels like a spare piece who may not make his big-league debut as a member of this organization.

For each of Naylor's intriguing fantasy-relevant qualities, he does something else that subtracts from his potential value. He has huge raw power, but doesn't make much of an effort to get to it consistently in games. One of pro sports' modern marvels is how well Naylor runs, given his pear-shaped physique. But he won't remain this nimble as he gets into his mid-20s. Prior to 2017, he hardly walked -- a red flag for a bad-body first baseman. However, his career-best 9.1 percent walk rate at Double-A helped lessen those concerns. At the same time, he pulled the ball a career-low 31.4 percent, which was the second lowest rate in the Texas League. For a player who is already not capitalizing on his top physical tool, this new passivity is quite troubling. Naylor could be a high-average 15-to-20 homer hitter, or a low-average 30-plus homer threat, but it's hard to see both skills converging. He has been promoted aggressively since being drafted 12th overall in 2015, and could be pushed to Triple-A before he turns 21 in late June.

Naylor was one of the more desired pieces in the infamous Andrew Cashner-Jarred Cosart deal, which nearly fell through due to alleged misinformation provided by the Padres. The Padres were able to keep Naylor, though, and he more than held his own during his first season of full-season ball. In 122 games between Low-A Greensboro and High-A Lake Elsinore, the left-handed hitting Naylor batted .264/.302/.407 with 12 home runs, 75 RBI and 11 steals. Naylor needs to work on his patience at the dish, as he only drew 25 walks in 481 at-bats. However, he also does not strike a ton, as evidenced by his 84 strikeouts over the above-referenced 122-game span in 2016. The Padres are banking on Naylor's home run totals eventually catching up to his massive raw power. He may only be starting to scratch the surface of his enormous power potential.

After being selected with the 12th pick in the 2015 draft, Naylor injected a modicum of hope into perhaps the worst farm system in baseball. The Canadian slugger slashed .327/.352/.418 with one home run in 25 games in his first taste of professional baseball. Perhaps the most impressive aspect of this small sample is the 10.5-percent K rate that he posted after just turning 18 years old in June. He was drafted because of the plus power he offers from the left side, and to show those contact skills at such an early age has to really excite fantasy owners. While a case could easily be made that Naylor is the best fantasy asset in the Marlins’ system, it is also worth noting that he is at least four or five years away from the show, so drafting him in dynasty leagues will require extreme patience.
