25-Year-Old PitcherSP
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.

Records third win
PArizona Diamondbacks
October 1, 2022
Jameson (3-0) earned the win Saturday, allowing two runs on six hits and two walks over six innings against the Giants. He struck out seven.
ANALYSIS
Jameson's biggest mistake came on a solo home run from third baseman J.D. Davis with two outs in the sixth inning to cut Arizona's lead to 3-2. This was just the fourth major-league start of the 25-year-old's career, and he has allowed two runs or fewer in all four with three of them being quality starts.
