The Orioles have a pretty good lineup with power all over the place and a lot of projection from some of their young players. If healthy, they will put up runs with the best of them:
Roberts 2B
Jones CF
Markakis RF
Guerrero DH
Scott LF
Reynolds 3B
Lee 3B
Wieters C
Hardy SS
They have 5 20+ HR guys (Jones, Guerrero, Scott, Reynolds, Lee) two that could break the 20 HR plateau (Markakis, Roberts) and some good OBP guys in the middle of the order. They will also eat lefties for breakfast.
There's also the White Sox, who, with the addition of Dunn, and a healthy Quentin and Beckham, boast a pretty formidable lineup:
Pierre
Beckham
Dunn
Konerko
Rios
Quentin
Pierzynski
Ramirez
Morel
Power (20+ HR potential from Dunn, Konerko, Rios, Quentin, Ramirez, Beckham) and Speed (Double digit steal potential from Pierre, Beckham, Rios and Ramirez) mixed in with good on base ability from the middle of the lineup, and a very solid bench that works favorably in matchups.
