The Chicago Cubs will acquire reliever Tyson Miller from the Seattle Mariners, according to a report.

Seattle will receive Minor League infielder Jake Slaughter.

Miller returns to the Cubs, who used a fourth-round pick on him back in 2016. He has a 3.09 ERA and 12 strikeouts in 11 2/3 innings pitched this season.

The Chicago Cubs drew six bases-loaded walks in the fifth inning against the Pirates on Saturday, the most by a major league team in a single inning in 65 years.

The last team to draw that many free passes with runners at every base in one inning was the Chicago White Sox, who had eight in the seventh inning on April 22, 1959.

Paul Skenes' stuff was as electric as advertised.

A fastball that reached at least 100 mph 17 times. A slider that left major leaguers shaking their heads. An invention called a "splinker" that is a hybrid of a splitter and a sinker and dips and dives unlike any pitch anywhere in baseball.

Yet even at age 21, the Pittsburgh Pirates rookie knows all the "oohs" and "ahs" and knee buckles a ball that at times seems to explode out of his right hand can produce won't matter if he can't control it.

So while there were some positive takeaways from his major league debut Saturday -- seven strikeouts over four-plus innings and much, much later a 10-9 victory over the Chicago Cubs -- the top overall pick in last year's draft understands there is more work to be done.

The Cubs are inching closer to getting two of their better hitters back from injury, manager Craig Counsell announced Saturday morning.

Outfielders Cody Bellinger (ribs) and Seiya Suzuki (oblique) could be back with the team as soon as next week.

"Belli is a little ahead of Suzuki," Counsell said before the Cubs hosted the Milwaukee Brewers. "We're going through baseball activities, making sure they feel good coming out of that and then progressing."

Suzuki, 29, has been out since mid-April after tweaking his oblique running to first base, while Bellinger, 28, has missed the past two weeks after colliding into a brick wall while tracking down a fly ball.

Cubs ace Justin Steele is just about ready to return to Chicago's rotation after being sidelined since the season opener because of a strained left hamstring.

Steele is on track to start Monday against San Diego, assuming he gets through one more bullpen session with no issues, manager Craig Counsell said Friday. The left-hander was hurt trying to field a bunt at Texas in his Opening Day start.

"We've missed him for a month, and it'll be good to get him going," Counsell said.
