Copeland, 30, briefly cracked the majors back in 2015. He has taken five starts this year in the upper minors, working to a 3.81 ERA with 6.7 K/9 against 5.4 BB/9 in 28 1/3 innings.
11:48am: New York will likely also add another arm, Mike Puma of the New York Post reports on Twitter. It’s not yet clear who that will be, but Puma says the mystery hurler may currently be on the Double-A roster.
Peterson, 27, has pitched in the minors since 2012, when he was taken with a 20th round pick out of the University of Kentucky. He reached the Triple-A level briefly last year after a strong showing at Double-A, then returned to Las Vegas to begin the current campaign.
Over his 22 appearances this year, Peterson has thrown 27 2/3 innings of 3.58 ERA ball. He has held opposing batters to 18 hits and eight walks while racking up forty strikeouts.
While the New York organization surely preferred not to make any 40-man moves, the club’s pitching depth has been pressed to its limits by recent injuries. Noah Syndergaard was supposed to start today but ended up on the DL, leaving Jason Vargas to take the ball on short rest. And Steven Matz left his outing yesterday early, putting further strain on the relief unit. (Rather improbably, both he and Syndergaard were felled in succession by finger injuries.)
