Treinen gave up a hit and struck out one in the ninth inning Thursday but allowed an inherited runner to score, taking his first blown save of the season in a 4-3, 10-inning loss to the Marlins.
Nats manager Dusty Baker didn't want to use Treinen at all Thursday after he'd already pitched in the first two games of the season, but two rain delays and some rough performances from Shawn Kelley and Sammy Solis in the eighth and ninth left the Nats with little choice but to send their new closer back to the mound. Treinen's 5:0 K:BB through 2.2 innings so far still sends a strong signal that the team made the right choice, and despite Thursday's stumble the 29-year-old's job isn't in any jeopardy.
