Michael Urban of Comcast Sportsnet tweets, “No names yet, but the #sfgiants are working hard on a deal at this hour. More details to come if they come available.”

Since there are no names, we can only speculate given the rumors that we’ve heard over the last few days. Here are a few candidates:

Hitters: Adam Dunn (Washington Nationals), Prince Fielder or Corey Hart (Milwaukee Brewers – but it is believed that they are off the trading table, Jose Guillen (Kansas City Royals), Ty Wigginton (Baltimore Orioles), Jose Bautista (Toronto Blue Jays), Cody Ross (Florida Marlins), Lyle Overbay (Toronto Blue Jays)

Pitchers: Scott Downs (Toronto Blue Jays), Will Ohman (Baltimore Orioles), Brandon League (Seattle Mariners)
