Expect Yankee legend (closer doesn’t seem like enough of a title) Mariano Rivera to miss most of the rest of the week resting a sore groin, injured perhaps three weeks ago.  It’s in his left leg, which isn’t Mariano’s push off leg.  [SI]

Rockies closer Huston Street’s injury appears more serious, with Colorado closing down the Street because of bicep tendinitis.  Street says he’ll be out a week until the swelling and tenderness goes away.  [ESPN]

First, it was Michael Young, now Texas may be with Josh Hamilton (again) as he injured his lower back running the bases.  Hamilton is day-to-day.  [ESPN]

The amazing comeback of Aaron Boone from open heart surgery is complete – he not only played first base for the Astros against the Cubs last night, but one of his plays made ESPN’s top ten plays of the night.  [SI]

A less exciting comeback is that of Troy Glaus, who will likely just get a few pinch hitting appearances down the stretch for the Cards.  [ESPN]

Tension in Florida?  Hanley Ramirez is missing time with a sore hamstring, and his teammates called him out for his lackluster performance over the last few days and not playing while the team is trying to make a run at the wild card.  Among those not happy with Hanley is Dan Uggla, who not only took shots at Ramirez’s toughness, but ripped him for being the only well-paid player on the team.

Curt Schilling as a US Senator? He’s thinking about it – but because he’s not a registered member of the Republican Party in Massachusetts, he’d be running as an independent.  With the death of Ted Kennedy, there’s an open seat.  Why not the Bloody Sox hero?

Transactions… Other than more September call ups, here’s the other stuff…

Welcome back! Andres Torres (SF); David Patton (CHC); Jarrod Saltalamacchia (TEX); Doug  Mientkiewicz (LAD); Bobby Crosby (OAK)

Waiver Signings! Oakland claimed Jon Meloan from Pittsburgh.  Washington claimed Victor Garate from the Dodgers.  Garate must have injury issues, because his statistics show a VERY live arm tempered by frequent control lapses.  I’d let him recover for my minor league program…  Meloan has had a few chances, but really isn’t a prospect.  He’s “organizational depth”.
