Trey Mancini, 1B, OF - Baltimore Orioles Fantasy Baseball Sleepers Sn 

Season AB H Avg. HR R RBI 1B 2B 3B TB SB HBP SO BB Pts Roto
2018 (proj) 561 154 0.275 22 74 81 101 28 3 232 2 5 146 39 329.00 1722.18

2016 14 5 0.357 3 3 5 4 1 0 15 0 1 4 0 12.00 166.45

Mancini enjoyed a very good rookie campaign last season, belting 24 home runs and driving in 78 while batting .293 in the heart of the Baltimore lineup. A much less heralded prospect than teammate Austin Hayes, Mancini's 2017 output looks to have solidified him for the near future as an everyday outfielder for the Orioles. As long as he can maintain last year's production then he's a solid late round option to round out the position.

Christian Yelich, OF - Milwaukee Brewers Fantasy Baseball Sleepers Sn 

Season AB H Avg. HR R RBI 1B 2B 3B TB SB HBP SO BB Pts Roto
2018 (proj) 538 170 0.316 27 96 91 104 37 2 265 13 5 123 70 370.00 1715.19
2018 574 187 0.326 36 118 110 34 7 343 22 7 135 68 305.00 0.00
2017 602 170 0.282 18 100 81 132 36 2 264 16 6 137 80 402.00 502.52
2016 578 170 0.294 21 78 98 127 37 6 282 9 4 138 72 375.00 482.11

After putting together one of the finest young outfields in baseball, the Marlins blew it up this offseason, shipping Giancarlo Stanton to New York, Marcell Ozuna to St. Louis, and finally Yelich to Milwaukee. He should open the season hitting either first or second for the Brewers, but it's the move to this offense and this ballpark that is exciting. Marlins Park is one of the worst for left handed power in baseball, while Miller Park rates as one of the best. Though he's far from a power hitter, Yelich started to develop some pop in 2016, hitting 21 home runs followed by 18 last season. Still just 26 years old, he's one of the best young all around hitters in baseball and there's no reason not to expect an uptick in home runs. Part of the optimism stems from the fact that he's averaged 37 doubles over the past two seasons playing half his games in Miami, combined with what we saw this stadium do for Eric Thames and Travis Shaw (both lefties) last season. Yelich also runs enough (72 steals in 90 attempts over his first four and a half big league seasons) to benefit from Milwaukee's aggressive approach on the base paths, one that has them significantly ahead of the rest of baseball in stolen base attempts over the past two seasons. Yelich could easily make the leap to top ten outfielder this season.

Nomar Mazara, OF - Texas Rangers Fantasy Baseball Sleepers Sn 

Season AB H Avg. HR R RBI 1B 2B 3B TB SB HBP SO BB Pts Roto
2018 (proj) 569 157 0.276 26 85 85 101 28 2 241 3 5 121 56 343.00 1599.67
2018 489 127 0.260 20 61 77 25 1 214 1 4 116 40 188.00 0.00
2017 554 140 0.253 20 64 101 108 30 2 234 2 4 127 55 312.00 272.36
2016 516 137 0.266 20 59 64 118 16 3 219 0 6 111 39 314.00 311.62

Despite not turning 23 until the end of April, Mazara has already posted back to back 20 home run seasons for the Rangers. While the counting stats were lacking in his rookie campaign, 2017's production certainly holds some promise. In addition to last year's 20 bombs, Mazara also drove in 101 runs (up from 64) and hit 30 doubles (up from 13) despite logging just 38 more at bats than in his rookie year. The doubles number is particularly interesting, as we know with young players that a jump in that department can often be a prelude to more power on the horizon. The plate discipline still leaves a little to be desired, but his career .259 average becomes more palatable if he can continue on his current trajectory.

Gregory Bird, 1B - New York Yankees Fantasy Baseball Sleepers Sn 

Season AB H Avg. HR R RBI 1B 2B 3B TB SB HBP SO BB Pts Roto
2018 (proj) 492 125 0.254 30 77 86 69 25 1 212 3 5 125 64 271.00 1575.20
2018 272 54 0.199 11 23 38 16 1 105 0 5 78 30 77.00 0.00
2017 147 28 0.190 9 20 28 21 7 0 62 0 2 42 19 69.00 98.26

Bird is one of the biggest unknowns heading into the 2018 season, as injuries have derailed a once promising career for the young first baseman. But we saw flashes of that promise late last year and into the postseason. In limited action in 2015 and 2017 Bird has already totaled 20 career homers and 59 RBIs, and that's in a little more than 300 major league at bats. This is one of the best lineups in baseball, and if he can stay healthy (always a big "if" with him) then he's truly the type of talent that can return third or fourth round value, but can easily be had in the back half of drafts.

Bradley Zimmer, CF - Cleveland Indians Fantasy Baseball Sleepers Sn 

Season AB H Avg. HR R RBI 1B 2B 3B TB SB HBP SO BB Pts Roto
2018 106 24 0.226 2 14 9 5 0 35 4 1 44 7 38.00 0.00
2018 (proj) 445 107 0.240 14 59 56 68 22 3 163 22 6 153 45 234.00 1559.00
2017 299 72 0.241 8 41 39 55 15 2 115 18 4 99 26 168.00 334.09

Zimmer has been drawing Grady Sizemore comparisons since even before he landed with the Indians. Sometimes those comparisons are wanting, but in Zimmer's case this one is pretty fair. With early season injuries hitting the Tribe, the Indians called up Zimmer and plugged him into the lineup as a lefty platoon bat. The then 24 year old responded by hitting .241 with 8 home runs and 18 stolen bases in just 332 plate appearances. Much like his minor league career, the strikeouts continue to be an issue (he fanned 99 times), after striking out 131 and 171 times in his 2015 and 2016 minor league seasons respectively. That said, he also did manage to swipe 44 and 38 bags in those two seasons, and that speed was on full display last year when he nabbed 18 in 19 attempts in Cleveland. Playing time will be an issue again, but he's a plus glove and finds himself on the right side of a platoon split to provide some value as an end of the bench outfielder.

Lewis Brinson, OF - Miami Marlins Fantasy Baseball Sleepers Sn 

Season AB H Avg. HR R RBI 1B 2B 3B TB SB HBP SO BB Pts Roto
2018 382 76 0.199 11 31 42 10 5 129 2 4 120 17 107.00 0.00
2018 (proj) 515 133 0.258 21 65 71 81 26 5 211 23 5 131 43 279.00 1513.37
2017 47 5 0.106 2 2 3 4 0 1 13 1 1 17 7 11.00 43.89

The Marlin's addition of Cameron Maybin isn't ideal for Brinson, who prior to the signing looked like he'd take over in center field to start the season. Just 23 years old on Opening Day, Brinson was the key piece of the trade that sent Christian Yelich to Milwaukee. Though he had a less than stellar cup of coffee with the Brewers last season, the talent is obvious. While strikeouts continue to be a concern, it's worth noting that Brinson did hit ..349 over 470 AAA plate appearances the past two seasons. Should he make the major league roster out of camp, he's the kind of rare power-speed combo that could put together a 20-20 effort or better, even as a rookie.

Trea Turner, SS - Washington Nationals Fantasy Baseball Sleepers Sn 

Season AB H Avg. HR R RBI 1B 2B 3B TB SB HBP SO BB Pts Roto
2018 665 180 0.271 19 103 73 27 6 276 43 5 133 69 283.00 0.00
2018 (proj) 562 167 0.297 16 93 65 112 32 7 245 48 4 113 41 372.00 1415.13
2017 412 116 0.282 11 75 45 87 23 6 184 46 4 80 30 278.00 693.35
2016 307 105 0.342 13 53 40 82 14 9 176 34 1 59 14 240.00 600.34

Depending on the value of stolen bases in your league, there's a case for Trea Turner as a mid-late first round pick in most drafts. While a fractured wrist cost Turner nearly two months of 2017, through just 198 big league games he has posted a .304 average, 133 runs, 25 home runs, 86 RBIs, and 81 steals. That's a per 162 game pace of .304, 109 runs, 20 homers, 70 RBIs and 65 stolen bases. That's right, we're talking Dee Gordon/Billy Hamilton-type stolen base chops with 15-20 homer power at a position that isn't that deep to start with. He's not quite as safe as some of the more established players at the position, but the upside is pretty tantalizing with the 24-year old.

Orlando Arcia, SS - Milwaukee Brewers Fantasy Baseball Sleepers Sn 

Season AB H Avg. HR R RBI 1B 2B 3B TB SB HBP SO BB Pts Roto
2018 (proj) 563 147 0.261 15 62 68 102 27 3 210 15 3 109 41 311.00 1327.12
2018 348 82 0.236 3 32 30 16 0 107 7 1 87 15 114.00 0.00
2017 506 140 0.277 15 56 53 121 17 2 206 14 1 100 36 317.00 343.08
2016 201 44 0.219 4 21 17 29 11 4 75 9 0 47 15 94.00 144.75

Heading into his age 23 season Arcia already has more than 200 big league games on his resume. But there have been some growing pains along the way for the Brewers former number one prospect. To date Arcia has been mired in the bottom third of the order, as his glove was big league ready it seems long before his bat. But there are reasons to be optimistic about his development as a player. After hitting just .219 across 55 games as a rookie, Arcia upped his average to .277 last season and added 15 homers and 14 steals as the everyday shortstop. He doesn't possess elite power by any means, but another step forward as a hitter this season could force the Brewers to move him into the leadoff or number two hole in a very good hitting offense. Such a move would also open running opportunities up for a player who has 22 big league swipes to his name, but averaged better than 31 steals per 162 games across five seasons in the minors.

Aaron Hicks, OF - New York Yankees Fantasy Baseball Sleepers Sn 

Season AB H Avg. HR R RBI 1B 2B 3B TB SB HBP SO BB Pts Roto
2018 (proj) 476 120 0.252 18 68 65 75 25 2 185 12 4 104 63 263.00 1317.12
2018 480 119 0.248 27 90 79 18 3 224 11 3 111 90 209.00 0.00
2017 301 80 0.266 15 54 52 62 18 0 143 10 3 67 51 196.00 253.88
2016 327 71 0.217 8 32 31 56 14 1 111 3 0 68 30 159.00 201.36

Hicks figures to be a regular in the Yankees outfield, as Judge or Stanton are likely to occupy the DH spot in most lineup configurations. His 15 home runs last year in just 88 games were a bit of an eye opener, and Hicks managed 10 swipes in 15 attempts as well. Despite a season where his playing time was limited by injury and the depth of the New York roster, Hicks still posted hands down his best offensive season to date. His upside will be a bit limited by hitting in the bottom third of the order, but he could also post some nice power numbers from there given how deep the Yankee lineup is coming into 2018.

Gregory Polanco, OF - Pittsburgh Pirates Fantasy Baseball Sleepers Sn 

Season AB H Avg. HR R RBI 1B 2B 3B TB SB HBP SO BB Pts Roto
2018 (proj) 508 136 0.268 18 65 71 86 30 2 206 12 3 98 50 287.00 1306.09
2018 467 117 0.251 23 76 81 33 6 231 12 3 117 62 193.00 0.00
2017 379 95 0.251 11 39 35 75 20 0 148 8 3 60 27 209.00 231.63
2016 527 137 0.260 22 79 86 97 35 5 248 17 0 119 53 313.00 457.21

Once one of the more promising outfield prospects in the game, Polanco struggled with injuries and inconsistency in 2017 en route to a disaster of a season. That said, there's still upside here. The 26 year old outfielder has stolen as many as 27 bases (2015) in a season and hit as many as 22 home runs (2016). Also encouraging are the 69 combined doubles he hit between 2015 and 2016. If he is truly healthy coming into the season then there's certainly 20-20 upside and the hope is that he can improve on his career .252 average, which is certainly a possibility. There's no safety, but for where he can be had on draft day he's at least intriguing.
