Treinen struck out one in a perfect seventh inning Tuesday to notch his fourth hold of the season in a win over the Pirates.
Good outings from Treinen have been rare this season but he's showing faint signs of improvement, posting an 8:1 K:BB over his last five appearances (5.2 innings) despite being scored upon in three of those games. It's still too soon to risk having him active on a fantasy roster, but the 28-year-old might yet prove to be a useful contributor down the stretch for the Nats.
