Estevez has given up six runs and eight hits through 4.1 innings this spring.
The 23-year-old hasn't pitched above Double-A yet, and it has really showed. There are some promising things about his performance thus far, however, such as his seven strikeouts over that span. That being said, Estevez will definitely need to head back to the minors to develop more against advanced hitters before he gets a real look from the major league club.
