Huston Street (RHP ,SD) was forced to leave Friday's extra-inning loss to the Marlins after two-thirds of an inning with what would later be diagnosed as a right lat injury. It was originally feared to be a shoulder issue given Street's mannerisms before exiting, but it looks as if he's averted any sort of long-term issue, although a DL stint is still possible.

One day after it was announced that uber-prospect Bryce Harper was being called up by WAS, LAA decided to promote a top prospect of its own, 20-year-old Mike Trout (OF, LAA). Unlike Harper, Trout already has a taste of MLB experience, posting a .256 xBA, 116 PX and 96 Spd in 123 ABs in 2011, laying the seeds for would could become a potentially lethal power/speed combo.

The Orioles placed Alfredo Simon (RHP, BAL) on waivers Saturday, clearing up some questionmarks about the team's starting rotation, while also freeing up space on BAL's 40-man roster for additional offense. Simon compiled pedestrian stats in 16 starts for the Orioles in 2011 with a 6.6 Dom and 3.1 Ctl. However, his xERA (4.18) and slight uptick in Cmd from 2010 to 2011 (1.7 to 2.1) provides hints of usefulness.

SEA traded heralded starter Michael Pineda (RHP, NYY) to the Yankees not only to sure up their catcher position with Jesus Montero (C, SEA), but because they also had a sea of young arms waiting to fill the void. Felix Hernandez (RHP, SEA) and Jason Vargas (RHP, SEA) figure to anchor the top of the rotation, but beyond that things get a little muddled. 

Will Chris Perez's (RHP, CLE) oblique injury result in a closer-by-committee in CLE with Vinnie Pestano (RHP, CLE)? We tackle the Indians' possible ninth-inning shake-up, as well as the final spot in BOS rotation, Grady Sizemore's setback, and more.

Plus Alex Gonzalez, McGehee, Lowrie, Weiland, Willingham, Francisco, more.
