ST. PETERSBURG, Fla. – The Cubs had so much confidence in Kyle Schwarber last year that they made him their World Series designated hitter – less than seven months after major surgery on his left knee and with only two Arizona Fall League games as the warm-up – and expected him to deliver against Cy Young Award winner Corey Kluber and a dynamic Cleveland Indians bullpen.

Now? Manager Joe Maddon isn’t quite ready to make that leap of faith with Schwarber, even as the October legend closes in on 30 home runs this season and puts up a .900-plus OPS since his reboot at Triple-A Iowa this summer.

“The thing you’ve got to be willing right now with Schwarbs is understanding that he’s going to do that,” Maddon said Wednesday, pointing toward the right-center field seats where Schwarber launched Chris Archer’s 96-mph fastball the night before at Tropicana Field. “And then he might strike out with a runner on third base. You have to accept both sides.

“You’re playing for that (home run) based on his ability against that pitcher, also knowing that you’re going to see the punch-out in there, too. It’s just part of who he is right now.”

That would appear to be a part-time player, as Maddon went with Jon Jay’s contact skills in the designated-hitter spot against Tampa Bay Rays lefty Blake Snell and continues to think about what will give the Cubs the best chance to win the final stages of the National League Central race.

Looking back on his time with Rays, Maddon explained some of the creative tension within a small-market operation constantly looking for ways to find an edge. Maddon called it buckets of information, how certain data points and sample sizes should be used in free agency and trades, while others informed the daily lineup/bullpen decisions and why you had to look inside the numbers.

How do you assess Schwarber in 2017? During the time of the year when he narrows his focus and becomes extremely calculating, Maddon started talking about Schwarber in terms of player development and the future, which didn’t exactly sound like a vote of confidence.

“Big bucket, everybody’s going to love this guy,” Maddon said. “And then I think the smaller buckets are going to get even more attractive. I do believe the more he plays in the years to come, you’re going to see the strikeouts come back down, a better adjustment when the count gets deeper.

“He’s already trying to choke up. I don’t know if you’ve noticed that from up top – he’s really trying to do different things in counts right now – and I’m starting to see some progress with that, too.

“But, God, the guy missed all of last season, and I still think that we all forget that sometimes. I thought he was a little bit better – when I first met him – at the ball with two strikes. I think that went away for a bit. Now I think he’s really trying to nurture that coming back.

“So I would say next year you’re going to see the same kind of power, but probably more contact when it’s needed. That’s the bucket he’s going to fall into.”

Coming off that dramatic World Series comeback, Schwarber fell into an offensive spiral that got him demoted to the minors three months ago. He’s still managed to blast 28 homers while striking out 31 percent of the time, struggling against left-handed pitching (.663 OPS) and batting .208 overall.

Schwarber also has the type of hard-charging personality that feeds off those doubts, loves the big-game pressure and creates energy for the rest of the team. There will be another chapter to his 2017.

“It is what it is,” Schwarber said. “That first whole part of the season was a wash for me. I was able to go down and just kind of get my head recollected and get some parts of my swing down.

“I can’t worry about the number up on the scoreboard. It’s just stupid to do that. So that’s all I’m worried about every time I go up to the plate – I want to put in a good team at-bat.”
