In addition to acquiring outfielder Eloy Jimenez and right-hander Dylan Cease as part of a four-prospect package from the Cubs, Hahn swapped international signing bonus pool money to Texas in exchange for 20-year-old infielder Yeyson Yrizarri, the Rangers' No. 17 prospect.
The three prospects debuted at No. 2, No. 8 and No. 30 in the White Sox farm system, giving the club arguably the best and deepest system in baseball. So who has stood out?
Jimenez, Class A Advanced Winston-Salem
Jimenez didn't take long to make an impact with his new organization, and he didn't travel far, either -- just to the other dugout. The Dash was playing Myrtle Beach, the Cubs' Class A Advanced affiliate, when the trade was consummated, making his first appearance an awkward one.
"I felt weird at the beginning," Jimenez said Friday through interpreter Billy Russo. "It was kind of a surreal situation, but you know, once the game started and I was on the field, it was just baseball. It was a connection, of course, but at the moment of the game starting, it was just baseball [and] I started feeling more comfortable. The situation was less weird for me."
Jimenez had a strong first weekend for Winston-Salem, going 4-for-10 with five RBIs and four walks over his first three games. The outfielder is the No. 8 prospect in baseball, per MLB Pipeline.
Reynaldo Lopez, Triple-A Charlotte
Lopez, the White Sox No. 6 prospect, may not be en route to the big leagues just yet, but his time could be coming. He was brilliant on Sunday, fanning a season-high 12 batters while tossing seven innings of one-run, two-hit ball against Gwinnett. He's on a run of four consecutive quality starts for the Knights, and he could be making his case for a second-half callup.
Jake Burger, Class A Kannapolis
The White Sox 2017 first-round selection has done nothing but hit at the professional level. After quickly earning a promotion from the Arizona League White Sox, Burger has continued to rake alongside May and June Minor League Player of the Month Micker Adolfo. Burger has gone 9-for-28 with a pair of doubles, a homer and an RBI over his first nine games with the Intimidators.
• There is no set date for when Yoan Moncada, the No. 1 prospect in baseball, will make his White Sox debut. Hahn said Friday there is no rush to get Moncada up before he's ready, adding a variety of factors will go into his decision.
"We'll see over the coming weeks," Hahn said. "But really the timeline is going to be driven by the conversations we have with our player-development people and if they feel this guy has done everything we've asked of him here and it's time to move him to the next level."
Moncada went 2-for-5 with a homer and two runs scored on Saturday, and he's 12-for-37 with a pair of homers over his past 10 games with Charlotte.
