After leaving Thursday's game with soreness, the White Sox are taking a cautious approach with pitching prospect Reynaldo Lopez.
The White Sox announced on Saturday they have placed Lopez on the 10-day disabled list with a strained back and purchased the contract of pitcher Danny Farquhar from Triple-A Charlotte.
White Sox pitching coach Don Cooper noticed Lopez losing both his velocity and command in the fourth inning of his start against the Texas Rangers on Thursday night which prompted a mound visit from manager Rick Renteria and head athletic trainer Herm Schneider. After initially walking back toward the dugout, White Sox first baseman Jose Abreu signaled for Renteria and Schneider to return. Lopez was pulled from the game just moments later.
Lopez is 0-1 with a 6.97 ERA in two starts with the White Sox after getting promoted to the majors on Aug. 11.
Farquhar, 30, signed with the White Sox in July after he was released by the Tampa Bay Rays.
In eight games with Triple-A Charlotte, Farquhar had a 3.00 ERA with a 0.880 WHIP and 12 strikeouts.
The veteran reliever has played in parts of six MLB seasons with the Toronto Blue Jays (2011), Seattle Mariners (2013-15) and Rays (2016-17). Farquhar has a career record of 7-14 with 18 saves and a 3.85 ERA in 230 games.
The White Sox 40-man roster is now at 36 after Saturday's move.
White Sox fans located in Chicago and Charlotte will get a glimpse into the future next week.
The White Sox announced they will promote pitching prospect Lucas Giolito to the majors and he will start in Monday's doubleheader against the Minnesota Twins. Michael Kopech, the White Sox No. 3 overall prospect, has been promoted to Triple-A Charlotte and will start on Monday night against Norfolk, the team also announced on Friday.
Giolito, who the White Sox acquired along with Reynaldo Lopez and Dane Dunning in an offseason trade from the Washington Nationals for Adam Eaton, is MLB Pipeline's No. 59 overall prospect.
After a shaky start to begin the 2017 season, Giolito has turned the corner as of late.
In his last five starts with the Knights, Giolito has a 1.71 ERA in 31.2 innings pitched. During that span, Giolito has a 28/11 K/BB ratio and opposing hitters are slashing just .221/.288/.319. The 23-year-old Giolito has a 6-10 record with a 4.48 ERA in 24 starts in 2017.
Giolito, a former first round pick of the Nationals in 2012, had a brief stint in the majors last season and had a 6.75 ERA in six games with Washington.
Kopech, who was a key piece the White Sox acquired in a blockbuster offseason deal with the Boston Red Sox for Chris Sale, has been nothing short of dominant in the minors.
Kopech has a 0.66 ERA with 54 strikeouts and seven walks in his last 41 innings with the Birmingham Barons. In 22 minor league starts this season, Kopech has a 2.87 ERA and a 1.148 WHIP with 155 strikeouts in 119.1 innings.
Kopech is currently MLB Pipeline's No. 1 pitching prospect in the minors.
Reynaldo Lopez's arrival to the South Side has created a spark of excitement in the latter part of the 2017 season, but that excitement may have turned into minor panic from White Sox fans after he was taken out of Thursday's start in Texas with an injury.
The whole scene was a bit odd with manager Rick Renteria and head athletic trainer Herm Schneider going out to the mound to check out Lopez in the fifth inning. Initially Renteria left after a somewhat short conversation with Lopez, but then Jose Abreu signaled for them to come back.
At that point, Lopez was removed from the game. Watch the video above to see the whole sequence.
The White Sox updated Lopez's status shortly after he was pulled from the game.
Lopez finished with 4 1/3 innings pitched and allowed six runs, five earned with six strikeouts, four walks and five hits allowed. Two of the runs were inherited runners that scored when Chris Beck relieved Lopez. Oddly enough, Beck was soon pulled with an injury as well.
Lopez had struck out three in a row after recording the first out of the fifth, but then allowed a walk and a single before being taken out.
