Konnor Pilkington Rejects Outright to Triple-A Rochester, Elects Free Agency

Konnor Pilkington cleared waivers, rejected an outright assignment to Triple-A Rochester and elected free agency, freeing him to sign with any club. The move removes Pilkington from Washington’s 40-man roster and gives the left-hander the chance to test the market after a season split between Rochester and the Nationals.

Pilkington, 28, worked out of the Washington bullpen in 2025 and logged a 4.45 ERA in the big leagues. "The 28‑year‑old Pilkington pitched 28 1/3 frames for the Nats in 2025, working to a 4.45 ERA with a strong 27.6% strikeout rate. The southpaw’s 13.8% walk rate was an eyesore, however, and marked the continuation of longstanding command issues that have plagued him since his early days in pro ball." Statistical accounts vary slightly on the inning total, with another outlet listing 28.1 innings and a 34:17 K:BB line, but the message is consistent: Pilkington strikes out hitters at an above-average clip while control remains the clear weakness.

The flip side of Pilkington’s MLB work was a promising stretch at Triple-A Rochester. "Pilkington still has one minor league option year remaining, and while his overall track record in Triple‑A isn’t good, he notched a 2.59 ERA in 42 1/3 innings with Washington’s top affiliate in Rochester this past season." That Rochester performance helped earn Pilkington the July call-up after Washington selected his contract on July 22, 2025. Yet his overall Triple-A résumé across parts of four seasons carries a 6.10 ERA and a 14.1% walk rate, underlining the volatility teams must weigh.

Pilkington’s broader career shows both upside and friction. He is a former third-round pick of the Chicago White Sox and has 88 1/3 big league innings with a 3.97 career ERA, roughly a 22% strikeout rate and a 12.9% career walk rate. Roster history is extensive: multiple option moves, designations and outright assignments dating back to his minor-league days and through stints with Arizona, Cleveland and Washington.

From a market and roster construction standpoint, Pilkington profiles as a reclamation target. "Rival clubs could be intrigued by his uptick in velocity and the strikeout numbers following a move to the bullpen and take a flier on a minor league deal now that he’s a free agent, but he’ll need to rein in his walks considerably if he’s to carve out a long‑term role in the majors." That calculus makes Pilkington appealing as low-cost relief depth, especially to clubs that prioritize swing-and-miss fastballs and are willing to bet on mechanical fixes.

Fan reaction already surfaced in the comment section: "Go get him, Texas. He’s got more upside than a couple guys you’ve picked up so far, and still has an option." For Triple-A observers and front offices, the next step is straightforward: teams seeking high-leverage upside with manageable risk will monitor Pilkington closely, and his ability to cut the walk rate will determine whether free agency becomes a stepping stone or a longer detour.
