PHOENIX — By the time Dodgers right-hander Roki Sasaki reached the blue backdrop set up in the Surprise Stadium interview room, he’d diagnosed the issue.

“I think it’s because of the two-seamer,” Sasaki said through an interpreter. “It kind of caused my forearm to pronate a little more. Also my arm slot was a little down.”

Those arm-side misses had, after three straight walks, prompted manager Dave Roberts to temporarily pull Sasaki from his most recent spring training appearance. But even though that start, marred by a wild third inning, brought Sasaki’s Cactus League ERA to 13.50, he’ll enter his Freeway Series start Monday with a spot in the regular-season rotation already secured.

Roberts has repeatedly made that point clear.

However, when asked directly if Sasaki was one of the Dodgers’ 13 best pitchers right now, Roberts gave an indirect answer: “He is going to start the season in the rotation.”

Answering why the organization has been so bullish on the decision requires zooming out.

“As we look out two, three, four, five, six years, it is imperative for us to integrate talented young players under our roster,” president of baseball operations Andrew Friedman said during an interview with The Times last week. “And that requires patience. And we have to have that even with the insanely high expectations we have.

“We have to be able to balance those two things, or there are a lot of cautionary tales of large-revenue teams who have had a run of success, and then they fall off the cliff.”

Sasaki, 24, is one of those young players the Dodgers are counting on to bridge the gap.

When Sasaki was posted by Nippon Professional Baseball’s Chiba Lotte Marines before last season, upward of 20 teams expressed their interest in the young phenom who was coming to the United States through amateur international free agency.

In his debut season, he produced a 4.72 ERA through eight starts — before an injury the Dodgers described as a right shoulder impingement sidelined him for much of the rest of the season. When Sasaki returned, it was as a reliever, a role he thrived in through the postseason.

Sasaki enters Year 2 with just 47 major-league innings under his belt, including the regular season and playoffs.

“On top of all those other things that you’re adapting to and learning, you’re also learning a new ball,” Friedman said. “Roki could really command his fastball in Japan, and right now it hasn’t been as good. So how much of that is the ball, how much of it is mindset, how much of it is delivery just getting out of whack? All of those are fair questions, but I think it speaks to, we have to have a level of grace with this and work with him to continue his development.

“Because we’ve seen it at an extremely high level, and now it’s on all of us to help him get back to that.”

NPB baseballs are slightly smaller, tackier and have higher seams than MLB baseballs. Players making the transition to MLB also have to adjust to a different strike zone, style of play and the off-the-field challenges of living in a foreign country.

The season before Sasaki signed with the Dodgers, his future teammate Yoshinobu Yamamoto and the Cubs’ Shota Imanaga set the bar high with relatively smooth transitions. But they were also coming over at later stages in their careers.

“We’re very mindful that this guy is essentially two years, three years behind Yamamoto,” Roberts said, “as far as on the progression side, the development side.”

Sasaki has shown he can be effective out of the bullpen, but pigeonholing him in a relief role at this stage of his career would be a disservice to him and the organization.

The Dodgers have identified the addition of the two-seamer as a development that could help Sasaki stick as a major-league starter.

“It’s our job as coaches to get a player to understand the value of having a ball bear in and get in on right-hand hitters to keep them off the outside part of the plate,” Roberts said. “There’s a little bit of trying to pronate too much — trying to make the ball move, versus trusting his grip and his throw. But that’s a coach’s responsibility to [figure out,] how do we get him there, along with him feeling comfortable.”

The Dodgers have decided that, at least for now, the best setting for that growth is the major leagues. Across the industry, there’s an understanding that the gap between Triple-A and the big leagues is bigger than ever. That makes evaluating players in Triple-A all the more difficult.

“He’s not close to a finished product,” Roberts said. “But he’s 24. … You could look at a team that would potentially sign a veteran, turnkey starter, but we’ve got to get him to cut his teeth and deal with some things. That’s part of the growth.”
