AS TIME GOES BY by BILL ARNOLD

The San Diego Padres lead the majors with the highest percentage of RBIs produced by players under the age of 30. Through Thursday, 138 of the Pads 147 ribbies, or 94.6 percent, came from the under 30 set. As one would expect, the Padres have one of the younger rosters in the bigs at an average age of 27.0 years. In contrast, the Toronto Blue Jays, one of the older teams at 29.1 on average, had the highest percentage of runs driven in from players who are 30 or older (67.9%, 112 of 165). The Yankees, with an average age of 28.3 years, are transitioning from an older to a younger lineup with 60.2 percent of their RBIs produced by players under 30. The 30 over and under 30 RBIs for each major-league team, through Thursday, were:
