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.
27-year-old Justin Jirschele made quite an impression in his first season as manager of the White Sox Class-A affiliate in Kannapolis. He helped lead the Intimidators to the South Atlantic League championship, and was named White Sox Minor League Coach of the Year. Jirschele came on the podcast to speak with Chuck Garfien about how he went from playing minor league baseball with the White Sox to coaching in their system. He talks about how growing up with a dad who was coaching minor league baseball helped mold him as a manager who is wise beyond his years. Jirschele also gives a report on some of the top White Sox prospects he managed last season such as Jake Burger, Alec Hansen, Dane Dunning and Miker Adolfo.
The White Sox farm system is baseball's best, according to one of the people making those rankings.
In the wake of Major League Baseball's punishment of the Atlanta Braves for breaking rules regarding the signing of international players — which included the removal of 12 illegally signed prospects from the Braves' organization — MLB.com's Jim Callis tweeted out his updated top 10, and the White Sox are back in first place.
Now obviously there are circumstances that weakened the Braves' system, allowing the White Sox to look stronger by comparison. But this is still an impressive thing considering that three of the White Sox highest-rated prospects from the past year are now full-time big leaguers.
Yoan Moncada used to be baseball's No. 1 prospect, and pitchers Lucas Giolito and Reynaldo Lopez weren't too far behind. That trio helped bolster the highly ranked White Sox system. Without them, despite plenty of other highly touted prospects, common sense would say that the White Sox would slide down the rankings.
But the White Sox still being capable of having baseball's top-ranked system is a testament to the organizational depth Rick Hahn has built in such a short period of time.
While prospect rankings are sure to be refreshed throughout the offseason, here's how MLB Pipeline's rankings look right now in regards to the White Sox:
4. Eloy Jimenez
9. Michael Kopech
22. Luis Robert
39. Blake Rutherford
57. Dylan Cease
90. Alec Hansen
