The Braves made a late change to their starting plan Saturday, scratching Reynaldo López with left knee inflammation and moving Martín Pérez into the game against the Nationals. The switch came 35 minutes before first pitch and altered Atlanta's rotation for a key game in the four-game series.
For readers tracking the matchup now, Pérez was not an emergency name pulled from nowhere. He had already been scheduled to start Sunday before Atlanta pushed him up a day, giving the Braves a starter on short notice while keeping the rest of the series plan intact as best they could. The Braves had won the first two games of the four-game series, so Saturday still carried the chance to close the set with a clean sweep of the early work.
López, 3-1 with a 3.79 ERA, had been a steady part of the staff since returning to the rotation on June 26. He had gone from the rotation to the bullpen earlier in the season, made 13 appearances there, then came back to start and had made six starts since that move. His latest outing was a strong one: 5 2/3 scoreless innings in Baltimore on July 26, the kind of performance that normally buys a pitcher a regular turn, not a sudden scratch.
That is what makes the timing so sharp. A pitcher can look fully settled one night and be out of the plan the next, and left knee inflammation is the reason Atlanta gave for the change. The club did not say whether the issue would keep López out beyond Saturday, leaving the next turn in the rotation the question that matters most for the Braves. A pitcher who was well enough to dominate in Baltimore only days earlier is now the one whose status could shape how Atlanta handles the rest of the series.
Pérez, 6-6 with a 3.49 ERA, has worked both as a starter and out of the bullpen, making 16 starts and four relief appearances. Atlanta has already used him in a similar role before, and he again becomes the stopgap when the rotation shifts underneath the schedule. What happens next depends less on Saturday's game than on whether López is healthy enough to take his place back in line, because that decision will tell the Braves whether this was a one-day adjustment or the start of a longer absence.
