NEW YORK -- In yet another misstep for Moises Alou, the 42-year-old outfielder was removed in the seventh inning of Wednesday's rehab start with cramping in his left hamstring.

According to the Mets' public relations department, Alou felt pain in the hamstring after diving for a ball. He was playing left field for Double-A Binghamton in a road contest in Norwich, Conn., in an attempt to recover from a strained left calf, an injury that forced him onto the disabled list on June 13.

Only days earlier, general manager Omar Minaya said that the Mets expected Alou to be back healthy, the soonest being in games preceding the All-Star break or immediately following it. This latest setback is a hitch in their outfield plans, which were complicated by Ryan Church's move to the 15-day DL on Tuesday with post-concussion symptoms.

As has Church, Alou has been on the DL multiple times this season. He started the season on the shelf while recovering from hernia surgery, and 14 games later, he would again be rendered inactive because of the calf injury. He returned to the DL in mid-June with the same injury, and now there is this most recent predicament.

When Alou played for the Mets this season, he was a force in the batter's box. His average (.347) ranks as the second-highest mark of his career, with his best year coming in 2000, with Houston, when he hit .355 in 126 games.
