The Orioles should be aggressive in the trade market next week. The O’s gave it a good shot last winter in signing a lot of veterans but it just hasn’t worked out so far this year. With that in mind, Vladimir Guerrero, Derrek Lee and Kevin Gregg are likely at the top of the list of players the Orioles are willing to deal. Felix Pie and Koji Uehara could also be moved before next Sunday as well. Uehara’s name has popped up in a lot of trade rumors recently. The Orioles would probably kick in most of the cash for lefty reliever Mike Gonzalez if they could find a team that wants him as he has been a huge disappointment so far in Baltimore. The biggest chip the O’s have is righty starting pitcher Jeremy Guthrie. Guthrie has had back luck support wise from both the offense and the bullpen this year but he has done his part. The Tigers, Yankees, Red Sox and Cardinals would probably be the teams most interested in Guthrie. Out of the players mentioned above, none of them with the exception of Guthrie are in the O’s long term plans so it makes sense to deal them for players to help them in the future.
