Heyward has proven himself to be one of the game's best all-around players, but unfortunately, fantasy owners aren't really rewarded for excellent outfield defense. He has yet to grow into the kind of power bat he flashed in 2012 when he hit 27 home runs for the Braves. Heyward has yet to hit 15 home runs in a season since then. Heyward has, however, developed into a fine contact hitter, as he had a career-low 14.8-percent K rate and a career-high .293 batting average in 2015. He is also exhibiting increasingly efficient baserunning, as he stole 23 bases in 26 attempts (88 percent) last year and has 43 steals in 50 attempts (86 percent) over the past two seasons. Heyward never hit more than 18 home runs in his brief minor league career, so this could just be who he is, but at just 26 years old, Heyward could still tap into more power. He figures to slot in to a top-third lineup spot after signing with the Cubs in December.

If you subscribe to WAR, Heyward was a top-25 overall player in 2014, but his real-life value far outweighed his fantasy utility. The major-league leader in defensive runs saved with 32, Heyward improved his average by nearly 20 points and saw a dramatic spike in stolen base production, but he finished three homers shy of his 2013 total despite playing in 45 more games (209 more PA), resulting in a 60-point drop in ISO (from .173 to .113). He struggled against left-handed pitching to the tune of a .477 OPS, down from .802 in 2013, and he hit just .268 against four-seamers, well below the league average. There are some concerns that his issues against fastballs could be a lingering effect of him being drilled in the jaw with a fastball late in 2013, but he improved his contact rate to a career-high 82.2%, and his HR/FB rate (6.5%) figures to return closer to the mean (13.0%) in 2015. A November blockbuster sent Heyward to St. Louis, where he'll look to finally break out under the guidance of hitting coach John Mabry.

Three weeks into the 2013 season, Heyward, who had hit just .121 to that point, was forced to undergo an emergency appendectomy, and he continued to struggle immediately upon his return in mid-May. Slowly but surely, Heyward began heating up (.312 average in June), and he was off to a nice start to the second half before a broken jaw, the result of being drilled by a fastball, put him back on the shelf in August. All in all, Heyward hit .254/.349/.427 with 14 home runs and just two steals in 104 games. His ISO fell by nearly 40 points (from .210 to .173), and he took off on the basepaths a mere six times. There were some positive takeaways, however, as Heyward improved upon his strikeout rate dramatically (from 23.3 percent in 2012 to 16.6 percent), while also walking more frequently. He bettered his average against lefties by 40 points, and hit .322/.403/.551 after moving atop the batting order. Heyward is a likely candidate to lead off for Atlanta in 2014, and he's an obvious candidate to bounce back at the dish, after hitting just .199/.321/.323 on the road last year.

Heyward's power numbers took a big step forward in 2012 as he hit 27 home runs, more doubles and triples than ever before in his career, and easily set a new personal best in RBI and runs scored. He also stole 21 bases, more than he ever stole in his career, even in the minors. After suffering heavy sophomore struggles in 2011, his on-base percentage still has not come close to approaching the dazzling .393 OBP he posted in his rookie season, but it took a step back in the right direction at .335 in 2012 as his batting average also bounced back to .269. Sooner or later, Heyward should break out into a true MVP candidate. A lot of great players have done so in their age-23 season, which Heyward is entering. Even if it doesn't happen just yet, he will still be one of the most valuable fantasy outfielders available.

Heyward may have been the most disappointing player in fantasy baseball last seasons as he hit just .227 and was benched most of August in favor of Jose Constanza and later platooned with Matt Diaz against lefties (he struggled with just a .577 OPS against left-handed pitching). There are reasons to think he'll rebound as he's just 22 this season, he was bothered by a shoulder injury much of the season, he still drew walks at a decent rate and had a low .261 BABIP. A series of tests in the offseason also showed no structural damage in his shoulder. He needs to reduce his strikeouts and improve against lefties and last season leaves doubt he'll become an elite player. Still, the price for a young player with his talent and minor league track record may never be lower.

Heyward entered 2010 as the top hitting prospect in baseball and didn't disappoint. He finished second in NL Rookie of the Year voting after hitting .277/.393/.456 with 18 home runs while playing outstanding defense in right field. Heyward won the starting right field job in spring training and started off hot by hitting eight home runs with a 1.033 OPS in his first 31 games. However, he strained a ligament in his thumb on May 14 and continued to play with the injury before landing on the DL in July (and missed taking the field after being named to the All-Star Game), hitting .222 with a .689 OPS over that stretch. Once healthy, he hit .302 with a .875 OPS in the second half. Heyward has as much upside as any player in the game with excellent power, great strike-zone judgment, speed and an outstanding glove and arm in right field. He turned just 21 last season, so his initial performance in the majors shows he could quickly improve, especially given that he struggled with a hand injury much of the season. But there are some reasons for concern. Heyward struck out 128 times (75 percent contact rate) and hit just . 249 with a .755 OPS against lefties. Still, he drew walks at a strong rate (15 percent of plate appearances) and should see more power as he grows. It may not be too long before he's one of the best players in the game.

Heyward may be the best prospect in baseball after dominating at Double-A last season as a 19-year-old and he could be a fixture in Atlanta as early as 2010. Heyward hit .296/.369/.519 with 10 home runs at High-A and then hit .352/.446/.611 at Double-A before a three-game taste of Triple-A. His stats were even more impressive given that he turned 20 in August. He has all of the qualities you like to see in a prospect including excellent power, great strike-zone judgment, speed and all the tools to be a plus fielder. He'll likely start the season at Triple-A, but it may only be until late May or early June before he's in the everyday lineup for the Braves.

Heyward, the Braves' 2007 first-round pick could be a fast riser through the system after a strong 2008 season. He has all the qualities you like to see in a prospect including excellent power, great strike zone judgment, some speed and all the tools to be a plus fielder. He'll start the season at High-A Myrtle Beach and could be a factor in the majors as early as 2010.

Heyward, Atlanta's first-round pick in the 2007 draft, hit .288/.386/.404 in his first professional season in rookie ball. He has enormous power, good strike zone judgment and the tools to play right field. He's got a chance to rise very quickly in the system.
