NEW YORK -- This is one trip that's becoming awfully familiar to Moises Alou.
The 41-year-old New York Mets outfielder went back on the 15-day disabled list Friday, after making just one rain-shortened start since his last trip there.
Alou has been bothered by a left calf strain that already had kept him out of the lineup for 19 days. He returned to the lineup Tuesday against Arizona and singled on the first pitch he saw, but the calf stiffened as the game progressed.
When the game resumed after a 61-minute rain delay, Alou was out.
"I feel bad for him, I really do," manager Willie Randolph said, "because he wants to be here. Sitting in my office he was almost in tears."
Marlon Anderson took Alou's place in left field Friday night against Texas.
Alou, who began the season on the DL following hernia surgery, has been one of the struggling club's best offensive players when he's been healthy. He's batting .347 with nine RBI in only 49 at-bats.
"It's embarrassing (for him)," Randolph said. "Walking through the clubhouse, guys look to him and he's not there for them."
The Mets have been thin in the outfield all season.
Anderson had been out with a hamstring injury before returning Tuesday, and right fielder Ryan Church is on the 15-day disabled list with post-concussion syndrome. Reserve outfielder Angel Pagan is sidelined with a shoulder injury.
The club purchased the contract of outfielder Chris Aguila from Triple-A New Orleans this week to help fill the void. The Mets also recalled catcher Robinson Cancel from New Orleans on Friday to provide an extra bat.
In other moves, catcher Raul Casanova and infielder Abraham Nunez cleared waivers and were sent to New Orleans, and the club announced it had signed first-round draft picks Reese Havens and Brad Holt.
The 21-year-old Havens, the 22nd overall selection, hit .359 with 18 homers and 57 RBI as a junior at South Carolina. He's expected to start out at shortstop but could move to another position.
Holt, a compensation pick selected 33rd overall, was 11-1 with a 3.18 ERA in 15 starts at North Carolina-Wilmington.
Both prospects will start out at Class A Brooklyn in the New York-Penn League.
