St. Louis Cardinals rookie infielder JJ Wetherholt was placed on the 10-day injured list on Sunday, August 30, 2026, due to right wrist tendinitis.
Wrist Tendinitis Sidelines Standout Rookie JJ Wetherholt
The St. Louis Cardinals placed infielder JJ Wetherholt on the 10-day injured list with right wrist tendinitis, according to a team announcement reported by Mlbtraderumors. To fill the active roster spot, the Cardinals recalled infielder Cesar Prieto from Triple-A Memphis in a corresponding move noted by Bvmsports.
Wetherholt has experienced pain in his wrist for the last month, attributing the discomfort to a career-high workload according to Jeff Jones of the Belleville News-Democrat via Mlbtraderumors. He attempted a rest-and-recovery approach without success, as the pain intensified in recent days. Wetherholt is scheduled to see a specialist in Arizona and hopes for a minimal stint on the injured list as detailed by Mlbtraderumors.
Offensive Struggles and Heavy Defensive Workload
The physical toll showed up noticeably at the plate over the second half of the season. Yahoo Sports reported that Wetherholt hit just .201 after the All-Star break, seeing his overall OPS drop to .618. Before the break, the 23-year-old rookie batted .259 with 13 home runs and 10 doubles across 90 games.
Beyond anchoring second base with elite metrics, Wetherholt filled in at shortstop for injured teammate Masyn Winn, logging nearly 97 innings without a defensive error according to broadcast coverage on Yahoo Sports. That demanding stretch at shortstop involved longer throws and difficult defensive dives, raising questions about whether the extra pounding aggravated his wrist as noted by Yahoo Sports.
Defensive Dominance and Contract Security in St. Louis
Despite the offensive slide, Wetherholt’s rookie campaign stands out defensively. He ranks third in baseball with 22 Outs Above Average according to Yahoo Sports, trailing only Bobby Witt Jr. and Pete Crow-Armstrong, while pacing all National League second basemen by a wide margin. Across 115 games at the keystone, he committed only two errors in 491 total chances noted by Yahoo Sports.
The organization views him as a foundational piece. The Cardinals previously signed Wetherholt to an eight-year contract extension worth $112.5 million, a deal that can reach a maximum value of $132 million through incentives reported by Yahoo Sports. The contract contains no opt-outs for either side, securing the young infielder in St. Louis for the next decade according to Yahoo Sports.
Impact on the Rookie of the Year Race
The injury all but closes the book on Wetherholt’s pursuit of the National League Rookie of the Year award analyzed by Yahoo Sports. While Wetherholt maintains a strong 4.4 fWAR and superior defensive numbers reported by Mlbtraderumors, Cincinnati Reds standout Sal Stewart has surged ahead with dominant counting stats, including a league-leading 104 RBIs and 30 home runs noted by Yahoo Sports.
A recent reader poll conducted by Mlbtraderumors showed 40% favoring Stewart and 39% backing Wetherholt. With Wetherholt sidelined, Stewart holds a decisive advantage to lock up the honor according to Yahoo Sports.
Cardinals Roster Strain and Infield Outlook
Wetherholt becomes the third starting infielder lost by the Cardinals to injury in a single week, joining shortstop Masyn Winn (left thumb fracture) and third baseman Blaze Jordan (left ankle sprain) reported by Mlbtraderumors. The team also recently placed right-handers Andre Pallante and Hunter Dobbins on the injured list according to Mlbtraderumors.
Sitting at 68-69 and 4.5 games back of the final NL Wild Card spot with a 1.6% playoff probability evaluated by FanGraphs via Mlbtraderumors, St. Louis must lean on José Fermín, Cesar Prieto, and Ramón Urías to cover the middle infield while awaiting reinforcements noted by Mlbtraderumors.
