Austin Riley

Baseball is a game of adjustments. After getting the call to the majors in mid-May, Riley went off for nine homers in his first 18 career games, and he still had an OPS north of .900 at the end of June. Then the league caught up to him. Riley hit .169/.221/.324 with a 41.6 K% from the beginning of July until his placement on the IL with a knee ligament issue in early August. He made it back in September but never made the necessary adjustments, slashing an even-worse .132/.190/.263 over the final month of the regular season. Riley was then left off the NLDS roster. Given Riley's pedigree, we should expect skills growth and for him to eventually adapt to the different ways pitchers are approaching him. However, until we see it on the field, there should be some trepidation toward investing heavily in a player with Riley's level of swing and miss. It's not even a lock that he breaks camp with the big club.

Remarkably little has changed regarding Riley's outlook since he made his full-season debut in 2016. The 6-foot-3, 220-pound third baseman still projects as a No. 5 hitter who should provide 30-plus homer power while hitting .250 or .260. He was promoted to Triple-A in early May and missed a month in the middle of the season with a knee injury. After the calendar turned to August, Riley really heated up, hitting .289/.333/.570 with eight home runs in 129 PA. However, strikeouts (31.8 K%) were still an issue during that run and he was not exhibiting much patience (4.8 BB%), so this was not a case of a player being unfairly held down for service time reasons. Riley still has significant approach issues to work on against Triple-A pitching and won't turn 22 until April 2. With the Braves signing Josh Donaldson to a one-year deal and Johan Camargo coming off a 3.3-win (fWAR) season, there won't be any rush to get Riley to Atlanta.

It is pretty obvious at this point in the Braves' rebuild that Riley is the third baseman of the future. He held his own (109 wRC+) as one of the second youngest position players in the Florida State League, prompting an aggressive July promotion to Double-A. That's when he really made his mark. Were it not for teammate and baseball prodigy Ronald Acuna, Riley would have easily been the youngest player to get 200 plate appearances in the Southern League, yet he still proceeded to be 62 percent better than league average while posting his best BB/K (0.40) since rookie ball. He has prototypical size (6-foot-3, 220 pounds) for the hot corner and enough power to challenge for 30-homer campaigns in his peak years, especially in that park. He does not project to hit .300 in the big leagues, but he could be a .270 hitter who walks a decent amount and hits in an advantageous spot in the lineup. If he handles Triple-A the way he handled Double-A, we could see him in Atlanta this summer.

Riley celebrated his 19th birthday on April 2 and five days later got his first taste of life in the middle of a Low-A lineup. He struggled for the first couple months, as most teenagers do when they first face pitchers who can occasionally locate mid-90s cheese and spin breaking balls. However, he made the necessary adjustments and hit .289/.348/.581 with 17 home runs and a 61:22 K:BB over his final 279 plate appearances with Rome. Also notable is the fact that Riley cut his strikeout rate from 32.6 percent in the first half to 21.8 percent in the second half. In a system flush with high-upside arms yet light on impact bat-first position players, Riley boasts the most raw power on the farm. That 65-grade power makes him a top-five third base prospect in the game and will allow him to challenge for the home run crown with High-A Florida while being one of the youngest hitters in the Florida State League.

Standing 6-foot-2 and 230 pounds, Riley generates impressive bat speed and power from the right side of the plate, more than enough to put him on the radar in long-term dynasty and keeper leagues. A supplemental first-round pick in 2015, Riley didn't exactly hit the ground running as a professional, batting .163 with no home runs in his first 14 games with the Gulf Coast League Braves. Riley would go on to hit 12 home runs in his final 46 games between the GCL and Danville of the Appalachian League. He also showed good patience for an 18-year-old, and has the arm to stick at third base. Look for Riley to receive his first full-season assignment in 2016.
