When does the All-Star break finish for the Mets? Ben Sheets, change the sheets, the sheet is about to hit the fan. However you want to view it, the Mets' season has clearly reached another critical juncture with yesterday's 6-1 loss at Turner Field that completed a Braves three-game sweep. "This is not the end of the world," Johan Santana said after the Mets lost for the fifth time in six games and fell 6 1/2 games behind the Nationals in the NL East. "We've got to continue playing and hoping at some point we rebound back and win a couple of series and get back to where we used to be."
