The Mets placed Moises Alou on the 15-day disabled list because of a strained left quadriceps after New York's 8-1 win over the Cubs on Wednesday night. The team called up Jason Vargas to start Thursday against the Cubs. The 24-year-old lefty is 2-3 with a 5.30 ERA at Triple-A New Orleans, but is 0-4 with an ERA over 9.00 in his last four outings. The Alou move is retroactive to May 13. He is hitting .318 with two homers and 13 RBIs, but is going on the DL for the 15th time in his career.
