CHICAGO -- White Sox bench coach Joe McEwing had a message for Rick Renteria during the five or six times he talked to the hard-nosed manager Tuesday, especially when Renteria asked what was going on around the team.
"I told him 'Don't worry about it. We've got this. Don't worry about it. Worry about yourself and getting healthy,'" McEwing said. "That's where our mindset is."
Renteria was released from the hospital in Minneapolis late Tuesday afternoon after undergoing a battery of tests for an episode of lightheadedness prior to last night's game, an 8-5 victory managed by McEwing in Renteria's absence. He will spend the night in Minnesota before returning to Chicago Wednesday, when he will undergo further testing at Rush University Medical Center under the supervision of Dr. Scott Palmer.
McEwing went to Target Field with Renteria on Monday, and he was totally fine. They went over the game plan, and McEwing went out to check the weather. When he came back inside, McEwing heard the news on Renteria.
"First things first. Our thoughts are with Ricky," McEwing said. "He's an amazing person, an amazing leader. He sounds great. He's a very tough individual.
"Once again, I'm more worried about him as an individual. He loves the organization and he loves this city and positive things are going to come out of today. I'm sure he wishes he could be here, but it's just worry about him and get healthy."
HYPE DESERVED FOR KOPECH 
Hector Santiago hasn't seen Michael Kopech in person since Spring Training. But the electric repertoire possessed by Tuesday night's starter and the No. 13 prospect in the game overall per MLB Pipeline stayed with the veteran left-hander.
"I know watching him in Spring Training he was stressed out about his changeup," Santiago said. "I'm like, 'With a fastball like that, just keep your slider and your curveball and you'll be all right.'
"Watching him throw next to me I was like I don't want to throw my bullpen. I'm trying to make the team and they were next to me and they were watching us all. His fastball compared to mine? Big difference.
"His stuff is electric. Has life on it. You see catchers' reaction back there. It's good stuff," Santiago said. "There's no doubt he can have a long career up here, a lot of success. It's a matter of how he takes it."
Santiago stressed for Kopech not to change the things he used to get him to the Majors.
"Same game, different stadium. A lot more people," Santiago said. "Just try to have fun and do the same things you did to get here. Just because you got here doesn't mean you have to change anything."
"He's going to put on a show tonight," White Sox shortstop Tim Anderson said. "He's going to do good."
THIRD TO FIRST
• An MRI Tuesday on outfielder Leury Garcia revealed a Grade 2 strain of his left hamstring that will sideline him three to six weeks. Outfielder Ryan LaMarre was recalled from Triple-A Charlotte to replace Garcia. Right-hander pitcher Tyler Danish was optioned to Charlotte with Kopech's contract being purchased from the Knights.
• The White Sox have listed James Shields (Thursday), Reynaldo Lopez (Friday), Lucas Giolito (Saturday) and Kopech (Sunday) as their starting pitchers in Detroit this weekend. With the team staying at a five-man-rotation, Dylan Covey appears to be the starter moving to the bullpen although nothing was officially confirmed Tuesday.
• Carlos Rodon, the current ace of the White Sox staff, made his debut in relief on April 21, 2015, at home against the Indians. He pointed to that role as one of the reasons why there's a little more hype around Kopech's debut.
"I was in the bullpen. I wasn't a starter. We were decent, plus we had freaking dudes," Rodon said. "We had (Chris) Sale, (Jose) Quintana, Abreu and (Jeff) Samardzija. I was the young kid."
