Found a couple transit tidbits checking on Sunday, I don’t use the 4 or MNR so I don’t know how relevant these are
The 4 is local through Manhattan this weekend

Yankee Game Day Service
For Harlem Line Yankees fans, frequent service to Yankee Stadium is available via a transfer at Harlem-125th Street Station for the 4-minute shuttle ride to and from Yankees-E.153rd Street Station. While station and track improvements are under way, reduced capacity means there is no direct service from the Harlem Line to Yankees-E. 153rd Street Station. As an alternative, fans can also drive to stations on the Hudson and New Haven Lines (where weekend parking is free at Metro-North-controlled parking lots) for direct service to Yankees-E. 153rd Street Station.
