Daily Dose: When celebrations go wrong

Ryan Dempster was put on the disabled list Tuesday with a broken toe suffered while celebrating Sunday's victory. Seriously. Dempster was attempting to jump over the dugout fence and onto the field after the final out when he stumbled and slammed into the ground. His teammates laughed at the time, but X-rays showed a non-displaced fracture and he'll also soon be missing a toenail.

Dempster has pitched very well since a poor April, posting a 3.57 ERA and 64/30 K/BB ratio in 75.2 innings spread over a dozen starts since May 1, but he'll likely miss at least three weeks and could be sidelined for more than a month. For now at least Kevin Hart has been tabbed to replace him in the rotation, but giving Jeff Samardzija a chance to start in the majors for the first time is also an option.

While the Cubs add to this season's extensive list of woes, here are some other notes from around baseball …

* Picking up Mark DeRosa two weeks ago looked like a solid deal for St. Louis at the time, but he went hitless in nine at-bats before suffering a wrist injury that put him on the disabled list Tuesday. General manager John Mozeliak called the DL stint a "precautionary move," but there are reports that DeRosa may be out for a long time after being diagnosed with a torn tendon sheath.

While admitting Tuesday that he doesn't "know all the jargon" DeRosa explained: "There's definitely something wrong with it. There's definitely a partial tear of the sheath. It's one of those things where you hope time allows it to heal itself." Now it's back to Joe Thurston and Brian Barden at third base for the Cardinals, who're in the same spot as two weeks ago except without Chris Perez in the bullpen.

* Despite being out for six weeks with a shoulder injury Erik Bedard didn't miss a beat returning from the disabled list Tuesday, striking out eight and giving up just two hits in an abbreviated four-inning start. Despite multiple injuries Bedard has yet to stop being a dominant pitcher in between DL stints and the impending free agent is now 5-2 with a 2.58 ERA and 73/23 K/BB ratio in 69.2 innings this year.

* Adam Wainwright was two outs short of a shutout Tuesday and Colby Rasmus backed him by going 3-for-5 with a homer as the Cardinals extended their lead in the NL Central with a 5-0 win against the Brewers. Rasmus' overall numbers are plenty strong, but the 22-year-old rookie has been fantastic since a slow first two months and is now 39-for-106 (.368) with 17 extra-base hits since June 1.

AL Quick Hits: General manager J.P. Ricciardi said Tuesday that the Blue Jays are willing to listen to offers for Roy Halladay, but was vague about the likelihood of a trade … Chicago has reportedly acquired reliever Tony Pena from Arizona for first-base prospect Brandon Allen … Scott Rolen extended his hitting streak to 24 games with an eighth-inning single Tuesday … Alfredo Aceves has joined the rotation in place of the Chien-Ming Wang and has AL-only upside … Shaun Marcum is said to be on track for an August comeback from Tommy John elbow surgery … Scott Hairston started in center field Tuesday and blasted his first A's homer … Justin Verlander allowed five runs Tuesday, but picked up his ninth win and struck out 11 … Grady Sizemore went deep twice Tuesday and has 15 RBIs since coming off the disabled list on June 23 … Jeremy Bonderman played catch from 60 feet Tuesday and said afterward that his shoulder "feels pretty good."

NL Quick Hits: Carlos Beltran (knee) has yet to begin high-impact workouts and likely isn't close to coming off the disabled list … ESPN reports that the Phillies are "more interested" in Pedro Martinez "than they're letting on" … Jose Reyes (hamstring) received a cortisone shot Tuesday, pushing his return timetable back even further … Kyle Lohse (forearm) gave up two hits over six innings in a rehab start Tuesday at Triple-A … Chipper Jones was scratched from Tuesday's lineup with a sore groin … Hanley Ramirez missed his third straight game Tuesday with a hip strain … Clayton Kershaw tossed six scoreless innings Tuesday, allowing two runs or fewer in his fifth straight start … Manny Ramirez was ejected from Tuesday's game for arguing a called third strike, but drove in three runs before leaving … Javier Vazquez tossed seven innings of one-run ball Tuesday, cutting his ERA to 2.95 … Freddy Sanchez (back) missed a fifth straight game Tuesday.
