CHICAGO -- During Yoan Moncada's first week with the White Sox, the No. 1 prospect in baseball per MLBPipeline.com, has picked up his first walk, first triple and first RBI.
A first home run can be added as of Wednesday night, with the second baseman going deep against Jacob Arrieta in the seventh inning of an 8-3 loss to the Cubs at Guaranteed Rate Field. Moncada connected on a 0-2 curve from the Cubs' right-hander, who had yielded one run on one hit until that point.
Moncada's drive to center carried 417 feet per Statcast™, with an exit velocity of 104.8 mph. He became the first White Sox player to hit his first career homer off of a Cy Young Award-winning pitcher since Josh Phegley against David Price on July 5, 2013.
"It means a lot because it was the first one of many that are coming," Moncada said through interpreter Billy Russo. "And I'm happy."
"That was his first career home run?" Arrieta said. "It was an 0-2 curveball. It was a good breaking ball but not in an 0-2 count when a guy is in swing mode, and he put a good swing on it. He had a pretty balanced swing."
Moncada has three hits in 23 at-bats since joining the White Sox. But those numbers don't tell the whole story.
There's a confidence and poise Moncada carries with him on everything he's doing. And even with eight strikeouts against four walks, Moncada has been able to work deep counts and track the ball at the plate.
"I'm going to say this. I think that there were -- and I'll probably get in trouble for this -- but there were a couple calls that he took, a couple pitches that he took for third strikes that were probably not strikes," White Sox manager Rick Renteria said. "And he took them.
"They weren't situations in which he would like to expand the zone a little bit, so he didn't. He comes back into the dugout, and if it's a situation where I say to him, 'Hey, you've got to expand it a little bit.' But that's not the case."

White Sox teammates gave Moncada the silent treatment when he returned to the dugout following the home run. They then quickly celebrated the blast.
Michael Kopech, baseball's top pitching prospect per MLBPipeline.com and No. 3 overall for the White Sox, tweeted out congratulations for Moncada and Rafael Devers, Boston's top prospect who hit his first MLB homer Wednesday in Seattle. Kopech, who struck out 12 over six innings in a victory for Double-A Birmingham on Wednesday, played with both last year in the Red Sox farm system.

Moncada received the baseball and said it will go in a special crystal case for his kids to know it was very meaningful for him.
"You can tell that guy has a lot of potential," Arrieta said. "He's pretty balanced in the box."
"It has been a nice week for me," Moncada said. "The results are going to come step by step. I'm just trying to enjoy the moment and try to take advantage of the experience and the opportunity to play here. I'm just happy I'm having this opportunity here."
