The Red Sox recalled left-handed pitcher Robby Scott from Triple-A Pawtucket and optioned right-hander Justin Haley to Pawtucket on Tuesday.
Scott, 28, has made 24 relief appearances for the PawSox this season, posting a 1.48 ERA (4 ER/24.1 IP) with 36 strikeouts, a 1.03 WHIP, and a .187 opponent batting average. Left-handed hitters have a .362 OPS against Scott, going 5-for-37 (.135) with one extra-base hit (double), two walks, and 17 strikeouts. Twenty of his 24 appearances have been scoreless, including 13 of his last 14. Since May 5, Scott has posted a 0.61 ERA (1 ER/14.2 IP) while holding opponents to a .137 batting average (7-for-51) and zero home runs. Signed by the Red Sox as a undrafted free agent in 2011, he is 3-1 with a 3.24 ERA (15 ER/41.2 IP) in 64 career Major League relief appearances (2016-17), having made his first career Opening Day roster with Boston in 2017.
Haley, 26, was selected to the Major League roster from Pawtucket on June 8. He made his Red Sox debut -- and his lone big league appearance of the season -- on June 13 at Camden Yards, throwing two scoreless innings in a 5-1 win over the Orioles. The right-hander is 3-6 with a 3.18 ERA (20 ER/56.2 IP) and 52 strikeouts in 11 starts for Pawtucket this season, including a 2.45 ERA (10 ER/36.2 IP) over his last seven outings. Selected by the Red Sox in the sixth round of the 2012 Draft, he spent his first five professional seasons (2012-16) in the Boston organization. Haley made the Twins' 2017 Opening Day roster and had a 6.00 ERA (12 ER/18.0 IP) in 10 relief appearances, the first Major League outings of his career.
