The Yankees selected right-hander Cale Coshow in the 13th round of the 2013 draft out of Oklahoma Christian University after he spent his freshman campaign a the University of Oklahoma. The imposing hurler agreed to sign and inked a deal that included a $100,000 signing bonus.
In his first taste of pro-ball, the 6’5″, 270-pound Coshow went 0-2 with a 3.76 ERA in 15 games for Staten Island in the New York Penn League. In 40 innings of work spanning 15 games, Coshow fanned 36 but showed command issues by walking 22.
Coshow again opened the 2014 campaign with Staten Island . He tossed three shutout innings in his only appearance there before receiving a promotion to Low-A Charleston. In six appearances for the RiverDogs, Coshow went 1-1 with a 5.19 ERA with 13 strikeouts and just one walk in 8 2/3 innings before suffering a shoulder injury. After coming back from the shoulder injury, the righty closed out the season Gulf Coast League by starting three games for the Yankees Gulf Coast League team; he went 0-1 with a 4.11 ERA with 19 strikeouts in 15 1/3 innings.
The 2015 season proved to be a breakout year in the system for Coshow. He earned a promotion to High-A Tampa for the first time in May after going seven-for-seven in save opportunities and holding opponents to a .179 batting average as the closer for Charleston. Once he arrived to the T-Yanks, the organization granted Coshow the opportunity to work as a starter as the development of his slider came along. He made nine starts for Tampa, putting together a 7-2, 2.24 mark in 16 appearances with a strikeout-walk ratio of 56-11. That earned him a shot at Double-A Trenton, where he compiled a 2-3, 3,51 effort in six starts to close out the season.
Coshow began the 2016 season in the Trenton rotation less than one year after beginning the transition from closer to starter. Despite posting a solid 3.49 ERA in nine starts for the Thunder, the Yankees organization opted to move Coshow back into the bullpen, where they believe he was best suited moving forward. The reliever spent the entire season in Trenton, going 3-8 with a 4.03 ERA in 36 games. Despite allowing 84 hits and issuing 50 walks in 89 1/3 innings, the Yankees liked how his stuff played out of the bullpen and believed that he could succeed in a back end role.
Thunder Manager Bobby Mitchell named Coshow the teams closer when the 2017 season began and despite blowing two of his first six save opportunities in April, he converted 15 of 19 save opportunities overall over the course of the season. Cale reached Triple-A for the first time in mid-august and went back up to SWB to end the season. In four games for the RailRiders, Coshow pitched to a 3.18 ERA in 5 2/3 innings. The Yankees opted to leave Coshow exposed to the Rule 5 draft early last month, but he was not selected despite reported interest from multiple clubs. Pinstriped Prospects asked Mitchell about Coshow’s 2017 campaign last month and he had the following to say: “I think that Cale turned the corner with us this year, maturity-wise. I think that he was his own worst enemy and you could see it sometimes on the mound. He would get riled and mad at himself and he didn’t have a short memory, which you need to have in a closers role day-to-day. I think that as the season went along, he matured and was able to control his emotions more during the game. I thought that he got one hundred percent better with his confidence. He got a lot better knowing that he wasn’t going to be perfect every time out there and I think he became a better teammate and I think the other players saw that. I was really happy to see him go up to the next level to see how he would handle it up there and he needed to be pushed a little bit to see if he could handle another level. He has certainly got the stuff; his stuff got so much better, his slider was much more effective and it was nearer to the zone and he started to get a lot of swings on that pitch.”
