Kodai Senga, Brooks Raley Facing Injury Concerns

8:02PM: Senga is day-to-day with tendinitis at the base of his index finger, the Mets announced.

5:41PM: Kodai Senga was supposed to make a Spring Training start for the Mets today, but Senga was scratched due to discomfort at the base of his right index finger.  Senga unfortunately isn’t the only Mets pitcher dealing with injury, as “a low-grade hamstring strain” has forced reliever Brooks Raley to be removed from the Team USA roster at the World Baseball Classic.  (Aaron Loup will take Raley’s place in the tournament.)

Mets manager Buck Showalter told reporters (including Newsday’s Tim Healey and MLB.com’s Anthony DiComo) that both Senga and Raley should still be able to be part of New York’s roster on Opening Day.  In regards to Senga, Showalter said the scratch was precautionary, and that “probably during the season, [Senga] would have pitched.”

As a reliever, Raley doesn’t need to rebuild as much arm strength in order to get back to full readiness.  Assuming his hamstring problem doesn’t linger, the left-hander might not require much ramp-up time to prepare for game action in the Mets’ remaining Grapefruit League schedule, or for the start of the regular sesason.

The Mets acquired Raley in a trade with the Rays back in December.  With Joely Rodriguez and Chasen Shreve departing in free agency, Raley was projected to be the top left-hander in the Mets bullpen, and perhaps even the only left-hander depending on how the club settles on its roster.  While the Amazins were comfortable with carrying only one southpaw (Rodriguez) in the pen for large portions of the 2022 season, having an all-righty relief corps probably isn’t preferable.  Since Joey Lucchesi is being stretched out as a starter, Raley’s injury might create an opportunity for minor league signing T.J. McFarland to break camp if Raley does indeed end up need more time to recover.

Senga will undergo imaging and tests on his hand, as the Mets will certainly take every precaution even if it seems as though Senga might have nothing more than a day-to-day setback.  Until the imaging results are known, however, the situation adds some level of concern over Senga’s highly-anticipated debut season in Major League Baseball.

Senga signed a five-year, $75MM contract with New York in December, as the 30-year-old’s strong track record in Nippon Professional Baseball generated plenty of interest in his services amongst MLB teams.  The New York Post’s Jon Heyman reported last month that the Mets did have some health-related questions about Senga prior to the agreement, though the exact nature of those concerns (and whether or not there’s any relation to Senga’s current finger problem) isn’t known.

Jose Quintana has already been sidelined with a stress fracture in his rib, so between Quintana’s injury and now this uncertainty over Senga, the Mets could potentially have two holes to fill in their rotation behind Max Scherzer, Justin Verlander, and Carlos Carrasco.  David Peterson had a scare of his own after he was hit in the foot by a comebacker earlier this spring, but Peterson suffered only a contusion and threw a live batting practice session on Thursday, so the southpaw should still be in line to take Quintana’s place.  If Senga also has to miss time, Tylor Megill is likely the next choice up on the rotation depth chart.

One possible obstacle to Senga’s readiness could be his lack of spring action to date, as he has pitched in only one game thus far.  The Mets were slowly bringing Senga into game action in order to better acclimate the right-hander to his new league, as Senga continues to adjust to the larger baseballs and steeper mounds used in MLB, as opposed to what Senga was used to in Japan.

Meanwhile, Quintana’s recovery timeline is yet to be determined, with Showalter telling Healey and other reporters that “they got a couple other people to look at some things and try to decide the best mode of operation which to go, as soon as we know exactly what we’re dealing with.”
