2024 Fantasy Outlook
Senga's first year in the majors couldn't have gone much better from an individual standpoint, as he made 29 starts and posted a 2.98 ERA, 1.22 WHIP and 202:77 K:BB across 166.1 innings. He joined the Mets on a three-year, $45 million contract after spending the first 11 years of his career in Japan, and he ended up being a bright spot on what was mostly a disappointing team in Queens. The 31-year-old struggled with walks -- his 11.1 percent walk rate was third worst among qualified starters -- but he helped offset the free passes with a 29.1 percent strikeout rate, 0.92 HR/9 and by stranding 80.3 percent of baserunners. A higher 3.87 xERA and 3.77 xFIP are hardly a surprise given his walk totals, so some regression wouldn't be surprising if he's unable to walk the tightrope quite so well in 2024. However, he regularly outperformed his peripherals while in Japan, so there's no reason to expect a precipitous drop after an impressive rookie campaign. Read Past Outlooks

Battling arm fatigue
PNew York Mets
Arm
February 21, 2024
Mets manager Carlos Mendoza said that Senga experienced arm fatigue during his side session Tuesday and is being evaluated by the training staff, Mike Puma of the New York Post reports.
ANALYSIS
Mendoza didn't sound too concerned that Senga was dealing with an injury that could threaten his availability for the start of the season, but the Mets likely won't know the full extent of the issue until he's evaluated further. Senga walked 11.1 percent of the batters he faced during his first season in the majors in 2023, but he otherwise made a smooth transition from Nippon Professional Baseball to MLB, pitching to a 2.98 ERA and 1.22 WHIP while striking out 202 batters over 166.1 innings. The Mets are counting on Senga to serve as the clear No. 1 starter in 2024 after the team shipped out Max Scherzer and Justin Verlander in midseason deals last summer.

Past Fantasy Outlooks
2023
2017
Senga has been one of Japan's best pitchers over the last decade, anchoring the staff for a Fukuoka SoftBank Hawks team that won six NPB titles. The Hawks don't allow their players to leave via the posting system, however, so Senga had to wait until his age-30 season to try his luck against the toughest level of competition. The righty has a large repertoire led by a fastball that has touched triple digits and a devastating forkball. Those weapons have helped him to a 2.59 ERA, 1.11 WHIP and 28.2 percent strikeout rate over the course of his career. He made the jump at the right time, having posted an even better 1.94 ERA and 1.06 WHIP in his final year in Japan. The Mets landed Senga for $75 million over five years, but he will assuredly use his opt-out clause after the 2025 season if he is healthy and has shown an ability to be effective in MLB. He has room to take a sizable step back from his NPB numbers and still serve as a capable mid-rotation arm at the MLB level, with upside for more, though durability could be a concern. He's eclipsed 150 innings in just one of the last six seasons.
The Japanese 23 year-old fastball/spliter pitcher emerged as a starter for Softbank Hawks in 2016.
