2024 Fantasy Outlook
Kikuchi enjoyed a career year in 2023 and finished with a 3.86 ERA, 1.27 WHIP, and 181:48 K:BB over 167.2 innings. He nearly cut his walk rate in half to 6.9 percent and had a solid 25.9 percent strikeout rate. A 3.77 xFIP also indicates his results were mostly earned, though a 42.4 percent hard-hit rate and 1.45 HR/9 were both bottom-10 among qualified starters despite being significant improvements from his 2022 marks. The left-hander, who will turn 33 years old in June, continues to average about 95 mph with his fastball and still generates plenty of whiffs, but those swing-and-misses have never really translated to equitable run prevention. Kikuchi's 2023 numbers certainly weren't a fluke, but that doesn't necessarily mean he'll be able to replicate them. A regression in 2024 shouldn't be the expectation but certainly wouldn't be surprising given the 5.02 ERA across his first four MLB seasons after coming over from Japan. Read Past Outlooks

Kikuchi (9-9) picked up the win Friday, giving up three runs on three hits and two walks over seven innings in a 5-3 victory over the Angels. He struck out six.
ANALYSIS
The lefty is now 5-0 over eight starts with the Astros with a 3.19 ERA, 0.94 WHIP and 59:12 K:BB through 48 innings, and he's proven to be one of the most astute acquisitions any team made at this year's trade deadline. Kikuchi's quality start Friday was his 10th of the season, and he'll look to stay locked in when he gets a rematch with the Angels back in Houston next week.

2016
Kikuchi is at a career crossroads as his non COVID-shortened seasons look terrible by most measures. His ERA and ERA estimators have been messy in each of those seasons, and then he further compounded problems in 2022 with a noticeable spike in his walk rate with a healthy dose of homers. Just six pitchers have ever thrown at least 100 innings with walk rates of at least 12% while allowing 2 homers per nine innings as Kikuchi did and those names include Oliver Perez, Andy Benes, and Derek Holland and each of their ERAs were over a full run higher than what Kikuchi somehow pulled off last season at 5.19. The strikeout rate was am impressive as he ran away from his cutter and threw more fastballs, but only his changeup was tough to hit for the league. It is perplexing to see someone with such poor overall numbers to have four pitches with Whiff rates above 25%, but that is what Kikuchi pulled off last season. Perhaps there is a brighter future for him in relief where he can pump up the velocity in shorter stints because he has had issues sustaining that over the course of a season. Funny data point: did you know Kikuchi's four-seam fastball generated more swings and misses in 2022 than four-seamers thrown by Justin Verlander and Alek Manoah? Now you do.
Kikuchi appeared set to deliver the breakout campaign that many projected prior to the 2021 season, maintaining a 3.46 ERA with an 81:26 K:BB across his first 80.2 innings and 13 starts. However, he crumbled from there, posting a 5.42 ERA across his last 16 outings. Perhaps coincidentally, his problems began with the crackdown on the use of foreign substances. When viewing Kikuchi's profile as a whole, home runs remain a significant problem (1.6 HR/9) and his walk rate also remains higher than would be desirable (9.3 BB%). However, by far the biggest problem for Kikuchi is the amount of hard contact he surrenders, highlighted by an 11% barrel rate, 47% hard hit rate, and 91.9 mph average exit velocity. Kikuchi agreed to a three-year, $36 million deal with the Blue Jays and will be pitching in the AL East for the foreseeable future.
On the surface, Kikuchi has had some rough sledding in his transition from pitching in Japan to pitching in the majors. Two consecutive season of bad ratios and a lack of wins while pitching for a perpetually rebuilding Seattle franchise. If you solely focus on the surface stats, you will miss the progress he is making as a pitcher. The southpaw added a new cutter in 2020 and made it his primary pitch, but like with anything new, it took some time getting used to. Kikuchi struggled with walks, but still struck out nearly a quarter of the hitters he faced and his expected stats do not look like they belong to a guy coming off a 5.17 ERA and 1.30 WHIP season. The cutter helped him greatly against righties as their weighted on-base average against him dropped 75 points year over year. Seattle is not a great team, but Kikuchi is a good pitcher whose surface stats create a strong buying opportunity in 2021.
Kikuchi fell far short of expectations in his first major-league season, posting a 5.46 ERA and 1.52 WHIP after recording a 2.50 ERA and 1.05 WHIP over three seasons in Japan. The 28-year-old struggled to miss bats, posting a 16.1 K% that would have ranked fourth worst among major-league starters had he logged enough innings to qualify, along with a middling 8.8% swinging-strike rate. The Mariners took measures to limit Kikuchi's workload as he adjusted to the rigors of the MLB schedule. The southpaw served up a whopping 36 home runs despite throwing only 161.2 frames, with right-handed batters teeing off to the tune of .304/.359/.545 against Kikuchi. He figures to have a rotation spot on a rebuilding Mariners club, but there is little reason to think a big improvement is coming in his second big-league season. Throw your dart elsewhere.
A three-time All-Star in Japan (2013, 2017, 2018), Kikuchi was 14-4 with a 3.08 ERA, an 8.4 K/9 and a 2.5 BB/9 in 2018. He has a mid-90s fastball that he uses to set up a plus slider. While not regarded in quite the same star tier of Shohei Ohtani or Yu Darvish, the 27-year-old lefty still projects as at least a solid mid-rotation starter in MLB. Kikuchi signed a three-year, $43 million deal with the Mariners, with a $13 million player option for a fourth year and a team option for a four-year, $66 million extension after the first three years. He was dominant in 2017, logging 217 strikeouts in 187.2 innings -- both career highs. Kikuchi was similarly dominant in 2018 until a shoulder injury caused him to miss a month, and while he was able to return, he wasn't quite the same after that. He will be adapting to a new schedule where he'll pitch more frequently, so we should not expect the 6-foot hurler to log more than 160 innings on a rebuilding Mariners team.
Kikuchi attracted attention as a high schooler for his hard fastball and stated desire to forego a pro career in Japan and jump straight to the majors. That didn't happen, and injuries have so far deterred him from reaching his potential. Still only 24, Kikuchi showed signs of improvement in 2015 and if he can put together a couple of healthy seasons, he could establish himself as a quality lefty.

Latest Fantasy Rumors
Emphasizing slider
PHouston Astros
September 10, 2024
Kikuchi has been utilizing his slider as his secondary pitch during the second half of the season while relying less on the curveball, per Eno Sarris of The Athletic.
ANALYSIS
The curveball's usage rate for the season still sits at 18.5 percent, which is on par with 2023, but he's thrown it only a handful of times in each start since being acquired by the Astros. Kikuchi has also thrown his slider around 40 percent or more of late as he's primarily shifted to a two-pitch mix, especially versus left-handed hitters. The results speak for themselves thus far, as Kikuchi has a 3.07 ERA, 0.98 WHIP and 53:10 K:BB across 41 frames in seven starts since the trade.
