Tyler O'Neill
24-Year-Old OutfielderOF
2019 Fantasy Outlook
O'Neill split his time in 2018 between Triple-A Memphis and St. Louis, and certainly flashed his big-league potential with nine home runs in only 142 at-bats while showing off an impressive outfield glove. The 23-year-old has little else to prove after posting a 1.078 OPS at Triple-A, but it remains to be seen if that success will translate to the majors. The big issue is his plate discipline. He posted a 40.1 K% and 4.9 BB% with the Cardinals. It was obviously a small sample size, but his strikeout rate ranked third worst in MLB among hitters with 100-plus PA, behind only Drew Robinson and Brett Phillips. Players like Aaron Judge have famously overcome similarly rough debuts, and O'Neill won't turn 24 until June 22. He will certainly get a chance to showcase himself come spring training, and has as much raw power as anyone on the roster. However, the Cardinals' outfield depth means he may be ticketed for Triple-A again to start the season. Read Past Outlooks

O'Neill (wrist) was activated off the 10-day injured list Friday.
ANALYSIS
O'Neill landed on the shelf with a left wrist strain at the start of August and will rejoin the Cardinals after being sidelined for nearly a full month. The 24-year-old has a .279/.316/.434 slash line in 46 games and figures to mostly work as the fourth outfielder for the stretch run.

Stat Review
How does Tyler O'Neill compare to other hitters?
This section compares his stats with all batting seasons from the previous three seasons (minimum 400 plate appearances)*. The bar represents the player's percentile rank. For example, if the bar is halfway across, then the player falls into the 50th percentile for that stat and it would be considered average.

* Exit Velocity and Barrels/PA % are benchmarked against 2019 data (min 400 PA) and Hard Hit Rate is benchmarked against last season's data (min 400 PA). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

Past Fantasy Outlooks
2018
2017
2016
The Cardinals netted O'Neill from Seattle for a soft-tossing southpaw (Marco Gonzales) who brings a 5.47 MLB ERA into his age-26 season. That's a good way of contextualizing how valuable the 22-year-old slugger is. He has posted isolated power figures above .200 at every stop above rookie ball, but his .293 average (.364 BABIP) at Double-A in 2016 now looks like an extreme outlier. The power is very legitimate, but so are his swing and miss issues. He has kept his strikeout rate below 30 percent over the past two seasons, but he is the type of a player who gets to the majors and immediately strikes out roughly 35 percent of the time because there are fewer mistakes to crush and big-league pitchers will exploit the holes in his swing. Throw in the fact that the Cardinals have a heap of young big-league-ready outfielders, and it's hard to see where he fits in. If he appears in line to get regular at-bats, he will be worth rostering in deeper formats, but not before then.
O'Neill does not look the part of a top-50 prospect. He looks like he could be the body-building nephew of Ty Wigginton or Casey McGehee. Right or wrong, scouts factor in physical appearance, which is one reason why it took so long for the 5-foot-11, 210-pound corner outfielder to emerge as someone prospect hounds took seriously. Another factor that limited O'Neill's value heading into 2016 was the amount of swing-and-miss in his game. However, for the first time since he was 18 and playing in the Arizona League, he posted a strikeout rate south of 30 percent (26.1 percent). He also walked at a career-best 10.8 percent clip and sported a 152 wRC+ while playing in the neutral hitting environments of the Southern League, putting to rest any concerns that his 2015 numbers were buoyed by the thin air of the Cal League. The power is plus, the hit tool is average, and the bandwagon is starting to fill up.
After hitting 13 homers in 57 games at Low-A in 2014, O’Neill exploded for 32 big flies in 106 games with High-A Bakersfield last season. There are some flaws in his game -- namely a dubious hit tool, an abundance of swing-and-miss and uncertainty about where he is best suited to play in the field. O’Neill’s 30.5-percent K rate last season was not completely irresponsible given his game power, but if his home run production dips then that K rate would quickly become more unsavory. His .260/.316/.558 slash line can also be downgraded a bit due to the extreme hitting environments of Bakersfield and the California League in general. He stole 16 bases on 21 attempts, but at 5-foot-11, 205, double-digit steals seem unlikely. O’Neill’s overall value will ultimately hinge on his hit tool. If he can hit .240 or .250, then he could be an everyday player in left field or DH.
