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
One more rehab start on tap
Imanaga (hamstring) will throw a bullpen session early this week before making the third start of his rehab assignment at Triple-A Iowa on Friday, Taylor McGregor of Marquee Sports Network reports.
ANALYSIS
Assuming he can make it out of Friday's outing without issue, Imanaga should be cleared to return from the 15-day injured list to make his next start with the Cubs either on June 25 or 26 in St. Louis. The left-hander made both of his first two rehab starts in the rookie-level Arizona Complex League, most recently pitching Saturday and striking out four over four shutout innings. According to Andy Martinez of Marquee Sports Network, Imanaga threw 44 pitches in that start and tossed 11 more in the bullpen immediately after exiting the game, so he'll presumably be looking to push his pitch count up into the 60-to-75 range Friday.

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.

Latest Fantasy Rumors
Could pitch in majors soon
Imanaga, who is working his way back from a hamstring injury, could pitch for the Cubs before the end of June, according to Vinnie Duber of The Chicago Sun-Times.
ANALYSIS
Imanaga pitched four scoreless innings in a rehab game Saturday in Arizona, and the star hurler is expected to make one more start with Triple-A Iowa before a decision is made regarding his return to the big leagues. If the rehab outing goes well, though, Imanaga could return to Chicago, and he'd be in line to pitch in the majors before the end of June as a result.
