2023 Fantasy Outlook
Jameson broke out as a high-upside starting pitching prospect in 2021, doing his best to shelve reliever concerns that stemmed from his stature (6-foot, 165 pounds) and control. However in 2022, he had to navigate extreme hitter's parks in Amarillo, Reno and the Pacific Coast League in general. He quickly forced a promotion from Double-A, but the PCL got the better of him over the span of 22 starts. It's not like he righted the ship prior to his MLB promotion -- he gave up 17 earned runs in his final 15.2 innings (three starts) for Reno. However, he was closer to the pitcher he was at Double-A against big-league hitters, going at least five innings in all four starts while tallying a 1.48 ERA, 1.11 WHIP and 24:7 K:BB in 24.1 innings. Jameson primarily threw his four-seamer, two-seamer and slider in the big leagues, also mixing in a changeup and curveball. The two mid-90s fastballs (can touch 97 mph) and mid-80s slider were his strikeout weapons, and while he did well in a small sample against lefty hitters in the majors, opposite-handed hitters logged a .933 OPS against him in the minors (.701 OPS against RHB). He might not have the truly dominant fastball/slider combo to get by without an offspeed pitch that neutralizes lefties, but the Diamondbacks will give him every chance to develop as a big-league starter in 2023.

Jameson was recalled from Triple-A Reno on Saturday.
ANALYSIS
Jameson made three starts and three relief appearances early in the season, winning two games and saving another, but he was optioned in late April despite recording a 3.71 ERA. His 16.0 percent walk rate was worryingly high, and while he cut that mark down to 8.9 percent across five Triple-A starts, he also posted a 5.79 ERA. His promotion Saturday comes in the same set of transactions as Brandon Pfaadt's demotion but also Zach Davies' return from the injured list, so Jameson may have to settle for a relief role for now.

Stat Review
How does Drey Jameson compare to other starting pitchers?
This section compares his stats with all starting pitcher seasons from the previous three seasons (minimum 120 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 120 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.
  • K/BB
    Strikeout to walk ratio.
  • K/9
    Average strikeouts per nine innings.
  • BB/9
    Average walks per nine innings.
  • HR/9

  • BABIP
    Batting average on balls in play. Measures how many balls in play against a pitcher go for hits.
  • GB/FB
    Groundball to flyball ratio. The higher the number, the more likely a pitcher is to induce groundballs.
  • Left On Base

  • Exit Velocity
    The speed of the baseball as it comes off the bat, immediately after a batter makes contact.

  • Spin Rate
    Spin Rate is the rate of spin on a baseball after it is released. It is measured in revolutions per minute (rpm).
