2025 Fantasy Outlook
When Imanaga and Yoshinobu Yamamoto signed in MLB last offseason, some considered Imanaga's stuff to be on par with, if not better than, fellow countryman Yamamoto's. However, Imanaga lagged in command while sporting a high home-run rate by Nippon Professional Baseball standards. To address both, the Cubs designed an apparatus to train Imanaga to throw his four-seamer up in the zone. His 1.4 HR/9 was high but palatable. His high riser also helped yield a low .264 BABIP while generating a high 17.6 percent swinging-strike rate. The biggest surprise was a scant 4.0 percent walk rate. A bloated 80.2 percent left on base mark fueled a 2.91 ERA, over half a run below expected. Even so, a mid-threes ERA with a strikeout rate around 25 percent plays in any format. Just don't pay for a repeat of last season's deflated ERA; a correction is likely on the way. Read Past Outlooks
Will need two more rehab starts
Cubs manager Craig Counsell said Tuesday in an interview on 670 The Score that Imanaga (hamstring) will need "a couple more" rehab starts before returning from the 15-day injured list.
ANALYSIS
Imanaga kicked off his rehab assignment in the rookie-level Arizona Complex League on Monday, tossing two scoreless innings. He will make at least two more rehab starts as he continues to get stretched out before returning to the majors later this month if all goes well. Imanaga has been sidelined since early May with a strained left hamstring.

2024 Fantasy Outlook
Imanaga is a 30-year-old lefthanded starting pitcher who was with the Yokohama DeNA BayStars of Nippon Professional Baseball since 2016. He was posted by his former club and is slated to make his MLB debut this season. Imanaga recorded a 2.80 ERA and 1.05 WHIP in 2023, fanning 174 in 148 innings. He throws a four-seam that's been reported between 92- and 94-mph, a slider, curveball, and split-finger changeup. The key to his success is fastball command and the effectiveness of his split-finger offering. Imanaga pitched for Team Japan in the 2023 World Baseball Classic and was deemed to possess the best Stuff+ by the Athletics Eno Sarris. Imanaga's main concern is he carried a high home run rate, especially relative to some of the other pitchers coming to MLB from Japan. He'll be working in bigger parks, but also facing better hitters. Chances are, Imanaga's ability to keep the ball in the yard will drive his major league success. He's expected to fill a mid-rotation role but shouldn't be expected to make more than 25 or 26 starts as he transitions to his new environment.
