On tap: The New York Mets, still within four games of the Washington Nationals in the National League East race and tied for the second wild-card spot (entering play on June 24), play a pair of crucial series this week. They visit the Nationals for three games June 27-29 before returning home to host the Chicago Cubs, owners of baseball's best record, for four games June 30-July 3. The team's health will surely influence these series, as Noah Syndergaard (elbow), Yoenis Cespedes (wrist) and Steven Matz (elbow) have had injuries call their Week 13 status into question.
