The New York Yankees have placed Kevin Youkilis on the disabled list with a lumbar spine sprain.

Youkilis had missed eight of New York's past nine games with the persistent back issue.

"It was just one of those things waking up, and I didn't feel right," Youkilis said. "Sometimes, after your adrenaline's gone, things occur to you. We've just got to find out what's going on."

There is no problem with the throwing arm of Washington Nationals right-hander Stephen Strasburg, who is not expected to miss his next start.

Strasburg was examined by a doctor after Monday night's loss to the Atlanta Braves. The team said he was suffering from tightness in his forearm.

Washington general manager Mike Rizzo said Strasburg's surgically repaired right arm is "structurally perfect."

Stephen Strasburg insists he won't miss his next start, but the Washington Nationals right-hander is dealing with tightness in his forearm.

He was examined by a doctor after his start against the Atlanta Braves on Monday night.

"I think he's got a little tightness in his forearm," Washington manager Davey Johnson said. "So they're going to put him on some medication."

Johnson said the hard-thrower will have to show he is ready to make his next scheduled start.

Strasburg insisted he won't miss a start.

"I'm not missing my next start," he said. "I'll tell you that right now."

Strasburg had lost a career-worst four straight starts before pitching six innings and getting a no-decision. He is 1-4 with a 3.13 ERA.

The Miami Marlins have placed Giancarlo Stanton on the disabled list with a strained right hamstring.

He was hurt in the 10th inning of Miami's 15-inning win over the New York Mets on Monday night.

Stanton said after the game that he heard a pop in his leg and that he fears the injury might be serious. He's scheduled for an MRI on Tuesday.

The New York Yankees have placed Francisco Cervelli on the disabled list with a broken right hand.

Cervelli broke the hand on Friday night against the Toronto Blue Jays.

The catcher left the game after just five pitches and underwent surgery Saturday morning at New York Presbyterian Hospital. He is expected to be out for six weeks.

In a related move, the Yankees have recalled Austin Romine from Triple-A Scranton.

Romine is hitting .333/.391/.405 with a home run in 42 minor league at-bats this season.

He was New York's second round pick out of high school back in 2007.

Colorado Rockies shortstop Troy Tulowitzki left Sunday's game against the Arizona Diamondbacks with a strained left shoulder after an awkward slide home.

He will be re-evaluated on Monday and was listed as day to day.

Tulowitzki is hitting .308/.394/.603 with six home runs and 22 RBIs.

Chicago White Sox right-hander Gavin Floyd left Saturday night's game against the Tampa Bay Rays in the third inning with a flexor muscle strain in his right elbow.

The 30-year-old was placed on the disabled list twice in 2012 with elbow soreness. The second trip was for a right flexor muscle strain.

"He has a strain right now. At least that is what we have it as, a muscle toward his elbow," Robin Ventura said. "It is looking more like a DL stint. It is kind of like he had last year. The hits just keep coming. We just have to find a way to keep going."

The Toronto Blue Jays expect Josh Johnson to return to the starting rotation late next week.

The right-hander was scratched from a start Friday night because of tightness in his right triceps.

John Gibbons says Johnson will throw on the side early next week and start a few days later "unless something changes."

Detroit Tigers right-hander Justin Verlander was forced to leave Thursday's start with a blister on his pitching thumb, but he is not expected to miss his next turn in the rotation.

The blister is something the right-hander has had to deal with in the past as well, according to Detroit's trainer.

Verlander left Thursday's game against Kansas City after seven innings.

Los Angeles Dodgers shortstop Hanley Ramirez will begin a minor league rehabilitation assignment Saturday and could rejoin the team as early as Tuesday.

When Ramirez had surgery March 22 to repair a torn tendon in his right thumb, doctors predicted he would be out roughly eight weeks.

He has said that he plans to come back much earlier.

Ramirez's return has been helped by a flexible splint that allows him to hit and make throws without further injuring his thumb.
