The Atlanta Braves made a roster move Sunday, placing right-hander Reynaldo López on the 15-day injured list due to left knee inflammation. The move was reportedly anticipated by the organization heading into the day's action.

To fill the roster spot, the Braves recalled right-hander JR Ritchie from Triple-A Gwinnett. Ritchie was tapped to start Sunday's game against the Washington Nationals, stepping into a rotation spot vacated by López's injury.

Left knee inflammation can be a tricky ailment for a pitcher, as the lower half plays a critical role in generating velocity and maintaining delivery mechanics. Placing López on the 15-day IL ensures Atlanta has a clear timeline to manage his recovery without rushing him back.

Ritchie, meanwhile, gets a high-profile opportunity to make his case at the big-league level. Pitching against Washington, he'll look to show the Braves' brass that he can hold his own while López works his way back to health.
