Few people know their way around the Island links like local wunderkind Tony Grillo. As President Obama settles into a vacation in West Tisbury that is almost certain to include a few rounds, Mr. Grillo leaves for Seattle to compete in the U.S. Amateur Championship. Before leaving, though, he spoke with the Gazette at his home course, Farm Neck, about what the duffer-in-chief can expect on Vineyard fairways.

Fit to win: Coach Philip Dwayne led the Celtics to a 2-1 victory on Wednesday over Monto Orthopedics in the Martha’s Vineyard Football Association competition. The game, a mid-season championship contest, was hard-fought. Eduardo DaSilva scored on a penalty kick early to put Monto ahead 1-0 at half-time. But the Celtics came back with two goals, both completed by Sam Griswold, in the second half to finish the match. The Island offers friendly and competitive leagues for soccer, softball for men and women, basketball and more, plus open tennis tournaments and a host of fun runs, including one this Saturday and another next.

FOUR FISH: The Future of the Last Wild Food. By Paul Greenberg. Penguin Press, New York, N.Y. July 2010. 304 pages. $25.95, hardcover.

The title is too narrow. Don’t think for a moment this is a book only about salmon, cod, bass and tuna.

For anyone who wonders where the swordfish went, how we emerged from the collapse of the whale fishery, or simply which fish is safe to order at the restaurant, Four Fish offers much.

If Matt Heineman is nearing his limit, he does nothing to show it this Sunday afternoon. The 27-year-old ran the Chilmark Road Race Saturday, but the 5K along Middle Road was just a warmup for this. Sunday is a marathon — specifically, the Alex Cohen Memorial Basketball Marathon.

If Matt Heineman is nearing his limit, he does nothing to show it this Sunday afternoon. The 27-year-old ran the Chilmark Road Race Saturday, but the 5K along Middle Road was just a warmup for this. Sunday is a marathon — specifically, the Alex Cohen Memorial Basketball Marathon. Mr. Heinemen first stepped onto the court behind the Chilmark Community Center at noon, and it’s now nearing 5:45 p.m. There have been breaks for the individual players over the past six hours, but the games themselves just keep going throughout the afternoon and into the evening.
