The Mets and Cardinals are set for a four-game series at Citi Field, beginning Thursday at 7:10 p.m. on SNY. Key points to watch include the potential resurgence of Kodai Senga, who has shown dominant form early this season, and Mark Vientos, who is experiencing a possible turnaround despite a slow start. The Cardinals, currently better than expected with a 9-9 record, feature strong offensive production and will challenge the Mets, particularly with starter Sonny Gray, who has been effective on the mound.
