It’s Deadline Day in the major leagues.

Here are several teams to watch between now and 4 p.m. ET.

Yankees: At last check, they had yet to upgrade their starting rotation. Ubaldo Jimenez is one physical exam from becoming a Cleveland Indian, and Hiroki Kuroda isn’t going anywhere. Do you really think the Yankees are going to sit this one out?

Braves: Carlos Beltran and Hunter Pence landed elsewhere, and the Braves still need a center fielder. Will they swing a deal for B.J. Upton, Michael Bourn, Coco Crisp – or someone else?

Rangers: Yes, they swung a deal for Koji Uehara. But what about Heath Bell?

White Sox: Kenny Williams is downplaying the chances for a major trade … which only heightens the intrigue. Despite hints at a possible shakeup, the White Sox are 5-2 in their last seven games. After moving Edwin Jackson, they’re interested in adding rotation depth at a low cost – a Bruce Chen type, perhaps.

Red Sox: Much like their rivals in the Bronx, the Red Sox haven’t made a significant pitching upgrade. And Theo Epstein is the type of general manager who won’t be afraid to make a big move right at the deadline.

Twins and Nationals: We’re all waiting on the Denard Span for Drew Storen trade.

Padres: They have a lot of bullpen inventory ready to move, not to mention outfielder Ryan Ludwick and starter Aaron Harang. The sale should start any minute now.
