Stat Review
How does Robert Stock compare to other relievers?
This section compares his stats with all relief pitcher seasons from the previous three seasons (minimum 30 innings)*. 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, Barrels/BBE %, Balls Hit 95+ MPH %, and Spin Rate are benchmarked against 2019 data (min 30 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

Past Fantasy Outlooks
2019
2010
Stock finally earned his first taste of major-league action as a 28-year-old and went on to throw 39.2 good innings, finishing the year with a 2.50 ERA. His underlying numbers back up his performance, as his 22.9% strikeout rate, 7.8% walk rate and 50.0% groundball rate all beat the league average, leading to a 2.71 FIP. If his 2.7 percent HR/FB rate regresses as expected, he'll look less like a high-leverage arm, but Stock should still be a capable middle reliever. His strong debut should be enough to secure a role this season in a Padres bullpen which is full of interesting but unproven arms.
Stock turned 20 after a successful debut in the Appalachian League. The 2009 second rounder was actually a pitcher in college, but he wants to catch and the Cardinals will indulge him for now. He has nice power potential and a mid-90s fastball (in case he ever goes back to his day job), but he's a long way from the majors.
