The Dodgers made it official Saturday: Landon Knack is off the 60-day injured list and back on the active roster, while right-hander Charlie Barnes got designated for assignment to clear the 40-man spot. It's a small move on paper, but for a Dodgers pitching staff that's been running on fumes for months, it's a real inflection point.
MLB Trade Rumors confirmed the corresponding moves on the Dodgers' 40-man roster.

Knack's road back has been a slog. He tore through spring training only to pick up a right intercostal strain that shut him down before the season even started, landing him on the 60-day IL in late April. Since then it's been complex work in Arizona followed by a rehab stint with Triple-A Oklahoma City, where he built up to multiple innings and shown swing-and-miss stuff without issue. Getting activated right around the All-Star break lines up with what Dodgers beat reporters had been signaling for weeks — the team wanted him stretched out enough to give real length, whether that's bulk relief innings or a rotation fill-in.
For a Dodgers staff that's leaned on openers, bullpen games, and a rotating cast of fill-ins for stretches of this season, getting a former starter with big-league track record back is a genuine boost. Knack has had flashes of being a legitimate mid-rotation arm in LA, and after this long a layoff, the front office is clearly betting his stuff plays even in a relief or swing role right out of the gate.
Barnes, on the other hand, becomes the corresponding casualty. The lefty had bounced on and off the roster all year as bullpen depth, the kind of up-and-down journey that comes with the territory for back-of-40-man arms on a team chasing a title. Now he's got a week to be traded, claimed off waivers, or outrighted, and the Dodgers move on with a fresher look on the mound.
None of this is a blockbuster, but it's the kind of maintenance move that matters more than it looks like heading into the trade deadline stretch. Every healthy arm the Dodgers get back internally is one less need they have to fill on the trade market, and Knack rejoining the staff gives Los Angeles a little more flexibility to be aggressive shopping for upgrades elsewhere instead of just patching holes in the pitching staff.
