Barrett, 27, is a former third-round pick who has thrown 93 1/3 innings for the Snakes over the past three years. He owns a 4.05 cumulative ERA with 8.5 K/9 against 4.3 BB/9.
Though he got off to a promising start back in 2016, when he worked off of a mid-nineties heater to generate a 12.3% swinging-strike rate, Barrett has since taken a step back. His whiff rate has trended down and his walk rate has gone up, leaving him with little in the way of MLB opportunities in 2018. He was effective last year at Triple-A, though, pitching to a 2.87 ERA with 11.3 K/9 and 4.9 BB/9 in 53 1/3 innings over 42 appearances.
