Beltran (Mets), Hart (Mil), or Ordonez (Det)?

My Startin Outfielders are Soriano (Cubs), Sheffield (Det) and Ordonez (Det, had him in because Beltran was slumpen, and he took off), however lately Ordonez has been struggling and Beltran picked up, so i've been playing Beltran. Trying to figure out this week, because even though Beltran has been scoring points, his batting average the last week or so has not been good, and Ordonez had a good game today, but before that he's been strugglin still, and I also have Hart (Mil) on the bench, who in the last month has done great, but in the last week not so great.
