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.

Back in big leagues
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.
