Treinen's adjustment to ninth-inning duties could be made easier by having Matt Wieters, who has plenty of experience catching for closers that rely on their sinker, behind the plate, Barry Svrluga of The Washington Post reports.
Wieters formed late-inning batteries with both Zach Britton and Jim Johnson in Baltimore, and Treinen's 95 mph sinker is comparable to Britton's overpowering offering. In fact, one of the first questions Nats GM Mike Rizzo asked the backstop before signing him was, "How do sinker-ballers attack the ninth?" If Wieters can help Treinen gain the same level of confidence in his primary pitch that Britton now enjoys, any potential closer controversy in Washington could be put to rest very quickly.
