The New York Mets have been struggling a bit recently, and some of those problems are coming on the mound. New York doesn’t have the same depth in its starting rotation that some of the other World Series contenders around the league do, and the injury to Kodai Senga has amplified that. Senga has been out ever since suffering a hamstring strain on June 12 while getting over to cover first base. As expected for any pitcher getting back on the mound after being out with injury, Senga was been a little bit up-and-down in his rehab outing on Saturday.
