Kodai Senga: Everything you need to know

Senga (back) completed a bullpen session Sunday, Laura Albanese of Newsday reports. Senga appears to have responded well since receiving an epidural to treat his lumbar spine inflammation, which forced him to the injured list April 28. He was able to start throwing again Wednesday, nine days after receiving the injection. Senga has now taken another step forward by getting back on a mound, but he'll still need to face hitters in live batting practice and then likely complete a minor-league rehab assignment before returning from the 15-day injured list. Senga had posted a 9.00 ERA and 1.95 WHIP in five starts prior to landing on the shelf and may not be assured a rotation spot once he's activated.

Mets manager Carlos Mendoza told reporters that Senga (back) played catch Wednesday, and the latter is progressing in his recovery, Laura Albanese of Newsday reports. "[Senga's] feeling a lot better, so now we've got to build him back up," Mendoza relayed Wednesday. Senga is working through lumbar spine inflammation that caused him to land on the 15-day injured list in late April. He'll struggled to a 9.00 ERA and 1.95 WHIP across 20 innings prior to landing on the IL, and he may need a lengthy rehab assignment before being cleared to return to the big leagues.

The Mets placed Senga on the 15-day injured list Tuesday, retroactive to April 27, due to lumbar spine inflammation. The right-hander has begun the season 0-4 with a 9.00 ERA through his first five starts, and he lasted just 2.2 frames during his last outing Sunday versus Colorado. According to Laura Albanese of Newsday, Senga received an epidural and will be shut down from throwing for at least 7-to-10 days. Once healthy and built back up, the Mets are likely to send Senga on what could be a lengthy rehab assignment to try and get him back on track. Christian Scott is poised to claim the open rotation spot after recalled from Triple-A Syracuse.
