Washington Nationals outfielder Bryce Harper was not in Monday's lineup and will probably also be out Tuesday because of knee bursitis.
Manager Davey Johnson told reporters before Monday's game against the Baltimore Orioles that an MRI showed no structural damage.
Nationals medical director Wiemi Douoguih told USA Today that Harper has inflammation of the bursa sac in front of his knee, but should clear up in a couple of days.
Harper could return as the designated hitter for Wednesday's game against the Orioles.
The Nationals placed left-handed pitcher Ross Detwiler on the 15-day disabled list with a strained oblique muscle. The move was backdated to May 16, so he'll be eligible to return Friday.
To fill Detwiler's roster spot, the Nationals recalled lefty reliever Xavier Cedeno from Triple-A Syracuse.
--- Milwaukee Brewers outfielder Ryan Braun was out of the lineup Monday with a right thumb injury. The All-Star is batting .311 with nine home runs and 33 RBIs this season.
---Cincinnati manager Dusty Baker told reporters that Reds ace Johnny Cueto and Chicago Cubs pitcher Matt Garza should settle their feud by duking it out.
Garza took exception to Cueto's pitch that sailed over the head of Cubs hitter David DeJesus in the sixth inning Sunday and called Cueto immature after the game.
"If he wants to say something to me, he knows where my locker is," Garza told reporters Sunday. "If he's got a problem, he can throw at me, and I'll do the same. Hopefully, he grows ... up. I hope he hears this."
Baker said he has not talked to Cueto about the incident but said Cueto was not trying to hit DeJesus. Then, he suggested Cueto and Garza should be allowed to fight each other.
---The Cleveland Indians placed closer Chris Perez on the 15-day disabled list with right shoulder soreness.
The club recalled left-handed pitcher Nick Hagadone from Triple-A Columbus to take Perez's spot on the roster.
Perez was injured in the ninth inning of Sunday's game against the Boston Red Sox. He was scheduled to have an MRI on Monday.
---Injured St. Louis Cardinals pitchers John Gast and Jake Westbrook were scheduled to fly out of Kansas City to visit doctors on Monday. However, Westbrook canceled his appointment after his right elbow felt better. Both are on the disabled list.
Gast was scheduled to see Dr. Lyndon Gross in St. Louis to have his sore right shoulder examined.
The Cardinals called up reliever Victor Marte from Triple-A Memphis and optioned right-hander Carlos Martinez to Memphis.
---The Pittsburgh Pirates placed outfielder Jose Tabata on the 15-day disabled list with a left oblique strain.
In a corresponding move, Pittsburgh recalled infielder Josh Harrison from Class AAA Indianapolis.
The Pirates also purchased the contract of left-handed pitcher Mike Zagurski from Indianapolis, transferred right-hander Jeff Karstens from the 15-day DL to the 60-day DL and sent righty Bryan Morris to Triple-A.
---The Seattle Mariners called up shortstop Nick Franklin from Triple-A Tacoma, according to the Tacoma News Tribune.
Franklin batted .324 with four home runs and 20 RBI in 39 games with Tacoma.
The Seattle Times reported that once-hot prospect Dustin Ackley will be sent to Tacoma.
---The Miami Marlins placed pitcher Alex Sanabia on the 15-day disabled list with a right groin injury and recalled left-hander Dan Jennings from Triple-A New Orleans.
Sanabia, who is 3-7, went just four innings in Sunday's loss against the Chicago White Sox.
