The Phillies are planning to call up right-hander Seth Johnson to start Sunday’s game against the Marlins, reports Kiley McDaniel of ESPN. It’ll be the big league debut for the 25-year-old righty, whom Philadelphia acquired from the Orioles in exchange for left-hander Gregory Soto prior to the trade deadline. Johnson is already on the 40-man roster, so the Phils will only need to clear space on the active roster to accommodate his promotion.
Selected with the No. 40 overall pick by the Rays in 2019, Johnson has now been dealt twice before making his major league debut. Tampa Bay sent him to the Orioles as part of the three-team deal that brought Jose Siri to the Rays and sent Trey Mancini from the O’s to the Astros.
It’s been a long and injury-paved road to the majors for Johnson. He made nine starts in the summer following his draft season, didn’t pitch in 2020 due to the canceled minor league season, and was limited to 93 innings by an elbow issue in 2021. That elbow injury flared up in 2022 after just seven appearances, requiring Tommy John surgery that shut Johnson down until late in the 2023 campaign.
The 2024 campaign has been the first full, healthy season Johnson has had since being drafted five years ago. He’s looked sharp, pitching to a combined 2.33 earned run average between the Double-A and Triple-A levels. That includes an excellent 1.52 ERA in 23 2/3 innings since being traded from Baltimore to Philadelphia. Johnson had strict workload restrictions early in the season with the O’s, rarely pitching more than four innings in a start. The Phils have slowly taken off the training wheels, so to speak, allowing him to pitch five innings, five innings and six innings across his past three Triple-A appearances. Johnson’s pitch count has climbed as high as 98 in that time, and he’s allowed only one run in that run of three starts.
Baseball America currently ranks Johnson seventh among Phillies farmhands, while FanGraphs lists him eighth and MLB.com tabs him 15th. He’s viewed as a potential mid-rotation starter — one with a heater sitting around 95 mph and a potentially plus slider, with less-impressive but still-developing offerings in his curveball and changeup.
The Phillies’ rotation has at times been as deep as any unit in the game this season. The fifth spot has been an exception since right-hander Spencer Turnbull incurred a lat strain that sent him to the 60-day IL, however. Veteran Taijuan Walker has spent time on the injured list and struggled through the worst season of his career when healthy enough to take the mound. Philly recently dropped him to the bullpen, and they’ll turn to a young arm in his place after optioning another in-house option, right-hander Tyler Phillips, on the heels of his own recent struggles.
The top four spots in the Phils’ rotation are set both this year and next, with each of Zack Wheeler, Aaron Nola, Cristopher Sanchez and Ranger Suarez locked into spots. Turnbull is a free agent at season’s end. Walker is signed for another two years, but with Johnson, Phillips and prospects Andrew Painter and Mick Abel among the starting candidates working their way toward the majors, Walker’s long-term outlook has become rather muddled.
