WASHINGTON -- Nationals right-hander Blake Treinen threw 45 pitches in a three-inning simulated game on Tuesday to prepare him for his next start on Saturday.
Treinen was scheduled to make his third start of the season on May 27 against the Marlins, but the game was postponed due to inclement weather. Treinen made his next appearance out of the bullpen in a 9-2 win over the Rangers on May 30. He didn't allow a run and gave up two hits with one strikeout in the eighth and ninth innings.
Treinen gave up three runs (none earned) on seven hits with two strikeouts over five innings in his first Major League start on May 6 against the Dodgers. The Nationals lost that game, 8-3. Treinen's next start was on May 22 against the Pirates, and he surrendered two earned runs on four hits with five walks over 5 2/3 innings in a 3-1 loss.
Treinen is a 0-2 with a 1.40 ERA in 19 1/3 innings this season. His next start will be in San Diego on Saturday night.
"He'll be ready for that," manager Matt Williams said.
