Funny, isn't it, what happens when the Red Sox' highest-paid players also are their best players? Carl Crawford and Adrian Gonzalez, in whom the Red Sox invested nearly $300 million prior to last season, combined to go 5-for-9 with three doubles and six RBI in a 9-2 rout of the Texas Rangers last night at Fenway Park. And there are signs it may not have been a one-game-only event.
