The Nationals have placed veteran reliever Lucas Sims on release waivers following a poor performance in a recent game against the Cardinals, where he struggled with control, hitting a batter and walking four others in a three-run inning. Sims, who signed a one-year, $3M deal with Washington, concludes his stint with 19 runs allowed in just 12 1/3 innings across 18 appearances, facing significant control issues. He will remain on waivers for two days, after which he is expected to become a free agent, likely limited to minor league offers due to his struggles.
