Note: Rest-of-season rankings are based on recent performance, past track record, and underlying data, similar to what is often used for fantasy sports lists. They do not necessarily reflect season-to-date results.

Summary: Not much movement inside the top 10. Roki Sasaki and Hiroya Miyagi retain the top 2 spots after an epic head-to-head duel last week, which saw Sasaki strike out 10 batters across 7 shutout frames and Miyagi punch out 13 over 8 innings of 1-run ball. Interestingly, Sasaki’s average fastball has dropped from 99-101 to 95-97, whereas Miyagi’s velocity is up from 89-91 to 92-94, but they’ve both found their groove.

Shoki Murakami, Tatsuya Imai, and Shosei Togo round out the top 5. Murakami has allowed just 3 runs over his last 31 innings. Imai has been utterly dominant, running the fastball up to the high 90s at times with a 1.29 ERA and 1.65 FIP on the year. Unless he suddenly loses his feel for the strike zone again, he’s firmly in the Sawamura Award conversation. Togo’s fastball is somewhat of an “invisa-ball” as it generates whiffs despite sitting just 90-92.

Hiroto Takahashi, Kaima Taira, and Hiromi Itoh are just outside the top 5. Takahashi was working out some kinks on the farm for most of April, so the top team sample size is minimal, but it’s clear he still has premier stuff. He struck out 11 and fell just one out shy of a complete game on Sunday night. Taira’s strikeout rate has taken a hit so far this year, but he’s getting more and more comfortable with his new gyro slider, he’s keeping runs off the board, and he’s still getting plenty of chase. Itoh has transitioned away from being a predominantly fastball-slider guy to throwing more cutters and splitters this year, and it’s working wonders.

Livan Moinelo is at #9, as his experiment as a starter has been going seamlessly thus far despite his gaudy stuff ticking down slightly. Kojiro Yoshimura joined the top 20 for the first time last week, and now he sneaks into the top 10 as he’s been the biggest breakout of the season so far, sporting a 2.18 ERA and 1.90 xFIP across 5 starts in his sophomore campaign. His fastball velo is up, his forkball has a 23.7 SwStr%, and his other secondaries are getting much better results, indicating his success is sustainable.

Spots 11 to 15 belong to Shunpeita Yamashita, Hiroto Saiki, Koki Kitayama, Tomoyuki Sugano, and Katsuki Azuma. Yamashita’s command has been all over the place this year, and he’s been sent to the farm to work on his issues, but there’s no question that the reigning Pacific League Rookie of the Year still has some of the best stuff in NPB. He’s one adjustment away from being a top 5 pitcher again. Kitayama is another guy breaking out in a huge way this year, maintaining a 1.29 ERA and 29.9 K% after 4 starts, though his 11.2 BB% is a bit concerning. Sugano looked all but “washed” coming into 2024 but is showcasing the best velocity of his career at the ripe age of 34.

Finishing off the list are Kona Takahashi, Atsuki Taneichi, Masato Morishita, Anderson Espinoza, and Shinnosuke Ogasawara. Notably, Takahashi and Ogasawara are candidates to be posted to MLB this offseason. Espinoza, a former top prospect for the Boston Red Sox, joins the top 20 with a remarkable 0.55 ERA through his first 5 NPB starts. He’s definitely due for regression, but he throws hard and gets enough grounders and strikeouts, so his success to this point isn’t entirely flukey.

Rank		Name	Notes
1 (-)		Roki Sasaki Lotte Age 22	Average velo is down from 99 to 96. A fair trade-off for more volume, assuming it’s intentional.
2 (+1)		Hiroya Miyagi Orix Age 22	24 IP, 1 ER, 23 K over last 3 starts. Pitches are up 2-3 mph across the board.
3 (+3)		Shoki Murakami Hanshin Age 25	Smooth sailing for the reigning CL MVP after a tough season opener.
4 (+6)		Tatsuya Imai Seibu Age 25	Keeping the walks in check for the first time in his career while boasting an average fastball of 95.3 mph.
5 (+2)		Hiromi Itoh Nippon-Ham Age 26	Better sequencing has led to a career-best Chase%, CSW%, K-BB%.
6 (+2)		Shosei Togo Yomiuri Age 23	Grinds through games and gets whiffs on his fastball despite subpar velocity. 40.3 Chase% leads NPB so far.
7 (-3)		Kaima Taira Seibu Age 24	Added a gyro slider and has been messing around with pitch mix. Diminishing returns so far but no big concerns.
8 (-3)		Hiroto Takahashi Chunichi Age 21	Still hasn’t pitched in NPB this season while working out some kinks on the farm.
9 (-7)		Shunpeita Yamashita Orix Age 21	Good news: 95-98 on the fastball. 2900+ rpm on the curveball. Bad news: the command is all over the place and he gave up 8 ER in 4 IP.
10 (+3)		Livan Moinelo SoftBank Age 28	1.73 ERA, 2.62 xFIP across 26 IP in his first go-around as a starting pitcher.
11 (-)		Hiroto Saiki Hanshin Age 25	Command is getting better. Almost 5:1 K/BB ratio over last 3 starts.
12 (-3)		Atsuki Taneichi Lotte Age 25	4 starts so far: 13 IP, 1 ER in two of them. 9 IP, 10 ER in the other two.
13 (-1)		Katsuki Azuma DeNA Age 28	Not quite looking invincible like last year, but still 4 for 4 on quality starts.
14 (NEW)		Koki Kitayama Nippon-Ham Age 25	Arguably the most dominant pitcher in NPB so far this year. 1.71 ERA, 2.12 xFIP. 34.2 K% over 21 IP.
15 (NEW)		Kojiro Yoshimura Yakult Age 26	Sitting 92-94 mph. 2.84 ERA, 1.65 xFIP, 28.2 K% after 3 starts. The sophomore breakout is legit.
16 (-2)		Chihiro Sumida Seibu Age 24	Has been solid but the strikeout stuff isn’t jumping off the page yet.
17 (NEW)		Kohei Azuma Orix Age 24	You expect him to slow down eventually but you can’t dispute a 1.64 ERA since 2022.
18 (-)		Kona Takahashi Seibu Age 27	Struggled in his season debut but looked closer to himself last start.
19 (-3)		Masato Morishita Hiroshima Age 26	Allowed 13 baserunners in 6.1 IP last outing. Advanced numbers are mostly in line with career norms.
20 (-1)		Shinnosuke Ogasawara Chunichi Age 26	Whiff% is concerningly low at just 9.8%. On the bright side, he hasn’t walked anyone yet this year.

Biggest Rise: Tatsuya Imai (+6)
Biggest Fall: Shunpeita Yamashita (-7)
Fell off List: Masashi Itoh, Yudai Ohno, Takayuki Katoh
Risers Outside Top 20 to Watch: Kodai Umetsu, Tomoyuki Sugano, Keiji Takahashi

Rank		Name	Notes
1 (-)		Roki Sasaki Lotte Age 22	Fastball is down from 99 to 96 on average but the stuff is unmatched when he’s on.
2 (-)		Shunpeita Yamashita Orix Age 21	7 BB in season debut raises some concerns but stuff is still overpowering.
3 (+2)		Hiroya Miyagi Orix Age 22	Fastball is up 2-3 mph and breaking balls remain top-class.
4 (-1)		Hiroto Takahashi Chunichi Age 21	Had mechanical troubles in spring but has thrown 16 scoreless innings tuning-up on farm.
5 (-1)		Kaima Taira Seibu Age 24	Career-worst 5 BB in season debut but held opposition scoreless anyway.
6 (-)		Shoki Murakami Hanshin Age 25	Had some bad batted ball luck and lasted just 3 IP in season debut.
7 (+1)		Hiromi Itoh Nippon-Ham Age 26	13 IP, 2 ER, 16 K to open the year. Chase% and CSW% are up.
8 (-1)		Shosei Togo Yomiuri Age 23	Fastball velo and GB% are down again but still getting the job done.
9 (+1)		Atsuki Taneichi Lotte Age 25	Struggled in most recent start but still missing bats. New knuckle curve yet to feature much.
10 (+10)		Tatsuya Imai Seibu Age 25	Fastball sitting 96. Slider getting whiffs. Much improved command, unafraid to attack the zone.
11 (-3)		Hiroto Saiki Hanshin Age 25	Still too fastball reliant, which is also down a tick. Still hasn’t maximized his crazy potential.
12 (-1)		Katsuki Azuma DeNA Age 28	Allowed 10 hits on opening day. Excellent BB% should continue to mitigate damage.
13 (NEW)		Livan Moinelo SoftBank Age 28	8 innings in first career start followed by 6 no-hit innings in second outing. Starter experiment is going seamlessly.
14 (+2)		Chihiro Sumida Seibu Age 24	Secondary usage is way up, which makes his fastball play much better. Changeup is elite.
15 (-3)		Masashi Itoh Hanshin Age 27	Same old Itoh. Lots of soft contact, not a lot of strikeouts.
16 (-2)		Masato Morishita Hiroshima Age 26	Was scratched from his first start with right elbow tightness.
17 (+1)		Yudai Ohno Chunichi Age 35	5 IP, 1 ER, 4 K in first start back after missing most of 2023.
18 (-5)		Kona Takahashi Seibu Age 27	Recorded 0 K in 6 IP in farm tune-up start. Velo drop of 3 mph is quite concerning.
19 (-2)		Shinnosuke Ogasawara Chunichi Age 26	Showed slight velo increase but wasn’t getting whiffs in his first start of the year.
20 (-5)		Takayuki Katoh Nippon-Ham Age 31	Still has a minuscule BB% but GB% has slipped to 30%. Red flag because he doesn’t have the stuff to offset it.

Biggest Rise: Tatsuya Imai (+10)
Biggest Fall: Kona Takahashi, Takayuki Katoh (-5)
Fell off List: Taisuke Yamaoka (Injured)
Risers Outside Top 20 to Watch: Koki Kitayama, Kojiro Yoshimura, Kohei Azuma
