The Nationals recalled pitcher Blake Treinen from Triple-A Syracuse on Thursday. To clear a roster spot, reliever Aaron Barrett was optioned to Syracuse.
The Nationals selected the contract of RHP Abel de los Santos from Double-A Harrisburg, the team announced on Monday. De Los Santos was 4-4 with six saves and a 2.65 ERA at Harrisburg. He replaces RHP Blake Treinen, optioned to Triple-A Syracuse. He was 2-2 with a 4.39 ERA with the Nats. To make room on the 40-man roster, outfielder Jayson Werth was moved to the 60-day disabled list.
Nationals reliever Blake Treinen appears to be putting his early season struggles behind him. After opening the season with a 6.00 ERA in his first 11 outings, Treinen has allowed just one run in his last five outings, lowering his ERA to 3.68. Treinen also has 11 strikeouts in his last 10 innings, including a six-strikeout performance during a four-inning outing May 14 at San Diego. "It's just being able to put the pitch where I want to, simplifying, not trying to make the best pitch, but make the pitch that's called and just execute location on it," Treinen said, per MASNsports.com. "The last couple of outings for me have been good evidence that it's working."
Nationals right-handed reliever Blake Treinen was just what the doctor ordered for manager Matt Williams on Friday. When starter Doug Fister was lifted after pitching just two innings against the Padres, Treinen came on and gave the Nationals threw 57 pitches over four innings, allowing three hits (including a solo home run) and struck out six along the way. Treinen hadn't pitched in three days, but he was happy just to play his role. "Every pitcher on the staff would take pride in doing their job and my job [Thursday] was to go out and get as many innings as we could," he said, per The Washington Post. "Am I glad that we're a couple arms fresher now? Absolutely. But it still sucks losing." The bullpen had been taxed pretty heavily over the last few days, so Trienen's effort allowed Williams to rest his tired arms. "We still have two lefties that will be fresh [Friday] and all of the right-handers with the exception of Blake so I think we're okay," Williams said.
Blake Treinen earned his first win of the season, over Atlanta on Tuesday. Treinen entered the game to start the seventh. He pitched two innings, allowing a run on two hits and three walks. The Nationals made him a winner by rallying for three in the ninth. Treinen improved to 1-2 with a 4.22 ERA.
