Prior to tonight's game against the Chicago White Sox, the Boston Red Sox selected right-handed pitcher Justin Haley to the active major league roster from Triple-A Pawtucket. To make room on the 25-man roster, the club optioned left-handed pitcher Jalen Beeks to Pawtucket following last night's game against the Detroit Tigers.
 
The Red Sox' 40-man roster is now at 39.
 
President of Baseball Operations Dave Dombrowski made the announcement.
 
Haley, who will wear number 65, has made 11 starts for Pawtucket this season, going 3-6 with a 3.18 ERA (20 ER/56.2 IP) and 52 strikeouts. The 26-year-old right-hander has a 2.45 ERA (10 ER/36.2 IP) since May 1, having allowed two runs or fewer in each of his seven outings in that time. Selected by the Red Sox in the sixth round of the 2012 June Draft, he spent his first five professional seasons (2012-16) in the Boston organization. Haley made the Twins' 2017 Opening Day roster and appeared in 10 major league games -- the first of his career -- before being returned to the Red Sox on July 24 in accordance with rules of the Rule 5 Draft. He spent the remainder of the season in Pawtucket and attended 2018 spring training with Boston as a non-roster invitee.
 
Beeks, 24, made his major league debut last night against Detroit, earning the loss after giving up six runs in 4.0 innings. The left-hander has also made 10 starts for Pawtucket this season, going 3-3 with a 2.56 ERA (16 ER/56.1 IP). He leads the International League in strikeouts (80) and ranks among leaders in WHIP (2nd, 0.98) and opponent batting average (3rd, .197), while his average of 12.78 strikeouts per 9.0 innings ranks first among league starters. Selected by Boston in the 12th round of the 2014 June Draft, Beeks was named 2017 Red Sox Minor League Pitcher of the Year and entered the 2018 season ranked by Baseball America as the organization's No. 11 prospect.
