The Colorado Rockies promoted right-handed reliever Carlos Estevez before Tuesday’s game against the St. Louis Cardinals, according to Troy Renck. To make room on the roster, they optioned right-handed reliever Jairo Diaz to Triple-A Albuquerque.
Nicknamed “Wild Thing”, the 24-year-old Estevez sports a 4-0 record in his 2017 campaign with the Rockies. He has an 8.10 ERA and 1.860 WHIP over 16 2/3 innings with six walks and eighteen strikeouts. With 25 hits allowed over that time frame, he’s allowed a BABIP of .429 while only yielding six extra-base hits, which suggests that the unsightly ERA and WHIP is as much bad luck as anything. He began the season on the Rockies major league roster but has been optioned back to the minors four times since then, the most recent option to Albuquerque happening on June 22nd.
Diaz, 26, spent the offseason recovering from Tommy John surgery, but has not had much success this year. He has a 9.00 ERA over five innings with 12 hits and five walks allowed against just two strikeouts. This is the second time this year Diaz has been optioned to Albuquerque.
