Who will join Moncada in The Show?

CHICAGO -- With Yoán Moncada now up and a big league regular, the wait continues for the next prospect domino to drop and join him at Guaranteed Rate Field.
The most likely candidate is White Sox No. 6 prospectReynaldo López, who is in the midst of a tear at Triple-A Charlotte. The right-hander, acquired this past offseason in the Adam Eaton deal, had his stretch of five consecutive quality starts come to an end but still dominated in his last outing, striking out 10 and allowing two over five innings on Wednesday.
With the White Sox ranking last in the Majors in quality starts this season, it could be a short wait for Lopez -- who is 6-5 with a 3.65 ERA in 20 starts at Triple-A this season -- to make his club debut.
Who else has stood out from the White Sox system, considered one of the best in baseball?

Eloy Jimenez, Class A Advanced Winston-Salem
Jimenez, the No. 7 prospect in baseball and the White Sox No. 2 prospect, has been incredible since being acquired earlier this month as part of the José Quintana deal with the Cubs. The outfielder has posted a .364/.426/.691 slash line with four homers and 14 RBIs -- good enough for a whopping 1.117 OPS -- in his first 16 games with the organization.
Lucas Giolito, Triple-A Charlotte
Giolito, like Lopez, was a part of the Eaton deal who could find himself in the big leagues before this season is over. The former first-round pick has gone seven innings in back-to-back outings, but has been hit-or-miss over his last 10 starts. The White Sox No. 7 prospect and No. 60 prospect in baseball has a 4.95 ERA in 21 starts this season.
Michael Kopech, Double-A Birmingham
Kopech, the club's No. 3 prospect and the No. 12 prospect in baseball, has appeared to figure things out over his last few starts. He's posted three straight quality outings, including his last start in which he allowed a run on two hits while striking out 12. Kopech likely won't see the big leagues this season, but has impressed with a 3.39 ERA in 19 starts at Double-A.
Worth noting
Right-hander Alec Hansen continues to deal, no matter what level he's at. The White Sox No. 9 prospect struck out 12 on Sunday, his most at the Class A Advanced level and his second-most this season after he struck out 15 for Class A Kannapolis. He's allowed two or fewer runs in four straight starts, including six one-run innings on Sunday.
