The Padres placed Matsui (groin) on the 15-day injured list Wednesday.
Analysis
Since straining his left groin in late February, Matsui has begun throwing off a mound and is slated to face hitters soon, but he'll still likely to remain on the shelf until at least around mid-April. Because he missed the entire Cactus League slate, he'll need to complete a rehab assignment in the minors before making his season debut with the Padres.

Past Fantasy Outlooks
2025
2024
Matsui was expected to compete for the Padres' closer role in 2024, but with Robert Suarez locking down that job, the left-hander was relegated to middle relief. After striking out 12 batters per nine innings during his 10-year career in Japan, Matsui's K-rate dipped after moving to the States. His 26.8 percent strikeout rate was still above league average, but Matsui's 10.5 percent walk rate likely prevented possible ascension to higher-leverage work. However, the 29-year-old racked up 236 career saves overseas and his vast experience closing games may still open the door for a greater role within the Padres bullpen.
Matsui signed a five-year, $28 million contract with the Padres in December, a deal which suggests he has the chance to close for his new club but isn't a lock to do so. San Diego is no stranger to the overseas reliever market, having signed Robert Suarez out of NPB prior to the 2022 season while also adding Woo Suk Go from the KBO this winter. Those two may wind up being Matsui's primary competition for the ninth inning this season, and if he can come anywhere close to repeating his numbers from Japan, he'll emerge as the favorite. The lefty may stand just 5-foot-8, and his four-seamer sits a modest 92-94 mph, but its rising action pairs perfectly with his devastating splitter, leading to a 2.40 ERA and 236 saves across his 10-year career in Japan. Over the last three years, he's produced ERAs of 0.63, 1.952 and 1.57, producing a 36.4 K% over that stretch. He hasn't always shown great control, with a 10.9 BB% for his career, but that number dropped to 5.9% last season. With a strong spring, Matsui could quickly move to the back of the Padres' bullpen.

Latest Fantasy Rumors
Could return in April
PSan Diego Padres
March 21, 2026
Matsui, who's dealing with a groin injury, will open the season on the IL but could return at some point in April, according to AJ Cassavell of MLB.com.
Analysis
Manager Craig Stammen ruled the southpaw out for Opening Day, but there's a chance Matsui could return to the bullpen at some point before the end of April. The southpaw suffered a left groin strain that kept him from pitching for Japan in the World Baseball Classic.
