We'll see when we reach August, when the 35-year-olds and 40-year-olds find out if their minds are making promises that their bodies can't keep. "It's a different game today with the drug testing and without amphetamines and steroids," says one very wise baseball executive. "Wait and see come the dog days. Those organizations that can bring up young players -- guys they know because they've been tested time after time in the minor leagues -- are going to have a huge advantage on the older teams."If that is the reality, where once teams sought veterans who have been through the wars, now teams like the Angels, Athletics, Red Sox, Indians, Braves, Diamondbacks and Dodgers may have their stretch drive solutions in house. Tampa, as well."We saw it last year when the Red Sox made their run through the World Series by bringing in [Jacoby] Ellsbury and Clay Buchholz and guys like that," another executive said. "I think it's going to be a younger man's game.""For instance," says the first executive, "look at the pitching market. Those 30-something sinker/slider relievers can't get up into the 90s any more without help, especially in the hot weather and in September. Everyone is looking for relievers. What is there out there? Chad Cordero, throwing 82-83? When the Red Sox were able to bring in Justin Masterson and Craig Hansen and see their power arms, that gives them something they can turn to in August. The Yankees have all those good young arms. Oakland's youth may keep them running with the Angels as they bring in a Nick Adenhart. Scouting and development is more important than ever. The teams like the Yankees and Red Sox and Angels who saw the game changing because of testing changing the culture are going to have an advantage."It may be that a team like the Giants, who eschewed the draft and compiled an older team to try to win one last time for Barry Bonds, could wilt. It could hurt the Tigers, who are an older team with little pitching left in the organization, while the Indians have Jeremy Sowers, Adam Miller and Aaron Laffey waiting in line. It could benefit the Marlins, who have outstanding pitching in Double-A. You may see the Padres move quickly to pull the plug on some of their older players and bring up Chase Headley, Matt Antonelli, Nick Hundley and Chad Huffman earlier than they intended. "We're entering a different era," says one AL GM. "We're now a couple of years into the testing, and I think come September we'll be saying 'this is becoming a young man's game.' Actually, we should have seen it last year when the Red Sox ran off with Pedroia, Ellsbury, [Jonathan] Papelbon, [Jon] Lester and those guys."*****Jim Leyland loved the stat in "The Bill James Gold Mine" that Magglio Ordonez led the majors in RBIs on singles."Some guys roll up RBI numbers in 15-20 games," says Leyland, "Mags will cut down and drive in the run when it counts. If you have a 130-RBI guy who'll punch the ball into right-center with the game on the line, you have someone special." Barry Bonds, for instance. Thanks to Rob Tracy of Elias, this is the list (through Thursday) of the players who have driven in the most runs on singles in 2007-2008:

51 Magglio Ordonez
49 Michael Young
47 Derek Jeter
45 Matt Holliday
45 Delmon Young
