CINCINNATI — Nationals C Wilson Ramos has a torn anterior cruciate ligament in his right knee, the latest major setback for the NL East leaders.
Ramos' knee buckled as he chased a passed ball during the seventh inning of a 2-1 win over the Reds on Saturday night. He fell on his back in pain and was helped off the field, putting little weight on the knee.
The Nationals feared that he'd torn the ligament, which was confirmed overnight by an MRI exam.
Ramos is the 11th Nationals player to go on the disabled list this season and the latest of several major-leaguers to tear an ACL this month.
"We're going to have to start eating bananas or something to change our luck," manager Davey Johnson said Sunday. "We've had more than our fair share of key players go down."
The Nationals called up C Sandy Leon from Double-A Harrisburg to back up Jesus Flores. Leon was batting .319 in 27 games at Harrisburg.
It has been a rough seven months for Ramos, who had one of the best rookie seasons in the majors last year. He went home to Venezuela to play winter ball and was abducted at gunpoint in front of his parents' home in Valencia.
Police commandos freed him two days later and arrested suspects who were trying to demand ransom. Ramos got 11/11/11 — the date he was freed — tattooed on his arm.
The Nationals have stayed atop the NL East despite a series of injuries. 3B Ryan Zimmerman recently returned from a sore right shoulder that forced him to miss 13 games. RH relievers Drew Storen and Brad Lidge, LF Mike Morse and utilityman Mark DeRosa were among those who went on the disabled list in April.
YANKS HONOR MARINE, DOG: The Yankees honored Marine Cpl. Megan Leavey and her 11-year-old bomb-sniffing German shepherd, Sgt. Rex, who worked more than 100 missions over two tours of duty in Iraq. Leavey waited five years to adopt Rex while he was still serving.
RF Nick Swisher presented Leavey with a jersey autographed by all the Yankees, and 3B Alex Rodriguez gave her a heart-shaped charm from Tiffany & Co with "Rex" written on it. Also, the team, with assistance from the Wounded Warrior Foundation, helped the Marines replace her Purple Heart medal, which was stolen during her rehab.
CARDS HONOR CHIPPER: Braves 3B Chipper Jones received a framed photograph of himself following through on a swing and a Cardinals jersey signed by Hall of Famer Stan Musial in a ceremony before his final regular-season game in St. Louis. Jones, 40, is retiring after this season. In other Cardinals news, 1B Lance Berkman was activated off the 15-day disabled list, and OF Shane Robinson was optioned to Triple-A Memphis.
WHEELER CUT: The Indians designated former Rays RH reliever Dan Wheeler for assignment. Wheeler, 34, has an 8.76 ERA in 12 appearances this season.
NEW RING FOR LOWE: The Red Sox presented Indians RHP Derek Lowe with a 2004 World Series ring to replace the one he had stolen from his Fort Myers home last month.
DODGERS: CF Matt Kemp left the game against the Rockies in the third inning because of a recurring hamstring problem.
GIANTS: LH reliever Jeremy Affeldt was activated from the 15-day disabled list, and INF Charlie Culberson was recalled from Triple-A Fresno.
ORIOLES: The contract of OF Xavier Avery was purchased from Triple-A Norfolk, and RHP Stu Pomeranz was optioned to Norfolk.
PIRATES: Closer Joel Hanrahan was reinstated from the bereavement list. RH reliever Daniel McCutchen went on the disabled list with a strained left oblique.
ROYALS: LHP Danny Duffy is scheduled for an MRI exam today after he left his start in the first inning with elbow tightness.
