Baseball is a sport of rhythms and routines, for fans and players alike. Those who don’t know it claim it’s soporific, and sometimes it is, but for the rest of us who care, we know to cherish its repetitive quotidian pleasures. Our own internal clocks are set by the baseball gods. Those gods haven’t been too friendly to the Yankees this year, and while this has been no excuse for the less-than-thrilling start, it has been somewhat of a frustration, especially for the fan. Consider a few facts: No team has played fewer games than the Yanks, who have already had five off days. This is the result of so much play on the road: A West Coast swing to start the season, then to the Midwest for another 3, then to Canada for a short series. (No other team has played as many on the road.) With the various home openers and special promotion days that come with the beginning of the season, they’ve played a host of day games. What time is the Yankee game? We’ve had starts this year at 12:30, 1:00, 4:00, 7:00, 8:00, and 10:00. It’s hard to keep track. So we welcome their return home today. The next week is the kind that we can set our watches to. Weekday games at 7:00. The weekend starts at 1:00. As it should be.
