Owen White, RHP, Rangers — White threw just 35.1 innings in the regular season, which stood as the only official professional action he'd seen since being drafted in 2018. Tommy John surgery and the pandemic wiped out his 2019 and 2020 seasons, and a broken hand in his first start this season kept him out until August. Even so, in that short time he's proven himself to be one of the most intriguing pitchers in Texas' system. He's also done a fantastic job navigating the highly hitter-heavy atmosphere in this year's Arizona Fall League. In four starts, righthander has allowed 10 hits while walking nine and whiffing 19. Notably, he'd walked five in 15 previous innings before Wednesday's outing—which was played at Salt River Fields where the automatic ball-strike system is in use—when he walked four hitters in 4.1 innings. His first four frames were excellent before he ran out of steam in the fifth and handed a bases-loaded situation to the bullpen. He now leads the league in ERA, wins, average against, WHIP and innings pitched.


Seuly Matias, OF, Royals —
In the words of the late Dave Niehaus: My, oh my, did Seuly Matias mash a baseball today. He has long been one of Kansas City's foremost raw power generators, but the thump has come with a lot of swing and miss too. Evaluators have seen some improvements in Matias' hit tool this fall, and after the organization turned the fortunes of M.J. Melendez and Nick Pratto his past season, there's hope that Matias could be the next in line. If Wednesday's game were at night, Matias' shot might have qualified as a moon blast. (Do not come at me with your "the moon still exists at night" takes.) He took a 68 mph hanging curveball and hit it at 109 mph at a launch angle of 35 degrees. That, readers, is the perfect example of a made-for-John Sterling home run: It was high. It was far. It was gone.

Spencer Horwitz, 1B, Blue Jays —
Though the AFL is packed with high-profile prospects, the league's batting leader has flown well under the radar. That would be Horwitz, whose two hits on Wednesday boosted his average to .408. His on-base percentage of .508 sits just eight points behind league leader Elijah Dunham. Horwitz didn't show profile power for first base during the regular season, but he controlled the strike zone with aplomb, drawing more walks (70) than strikeouts (68) between High-A Vancouver and Double-A New Hampshire. That trend has continued in the AFL, where Horwitz has nine walks and just six strikeouts in 12 games.
