The Cardinals announced after Friday night's game with the that they have called up top prospect Oscar Taveras from Triple-A Memphis, and will start on Saturday against San Francisco.

Taveras, a 21-year-old outfielder, was batting .325 in 49 games with Memphis with seven homers and 40 RBIs. He will take the place of Matt Adams, who was put on the DL with a left calf strain.

Nationals third baseman Ryan Zimmerman is scheduled to play five innings in left field Saturday night in his second rehab game with their Class-A farm team, according to an ESPN.com report.

Zimmerman has never played the outfield in the majors or minors.

Manager Matt Williams says "He's ready. He's done a lot of work out there."

David Ortiz outraged that David Price hit him Friday night on the first pitch the lefty threw to the Red Sox slugger since he hit two homers off him in Game 2 of the ALDS last October, said he has lost all respect for Price.

"It's a war," Ortiz said after the Red Sox rallied for their fifth straight win and second walk-off in two nights. "It's on. Next time I see him, he better put his gloves on. I have no respect for him anymore."

Price, asked after the game whether he had hit Ortiz intentionally, said: "I've got to establish my fastball in. I had six lefties in that lineup, that's my favorite side of the plate to go to. Got to establish it in."

Four members of the Red Sox were ejected during the team's 3-2, 10-inning win over the Rays at Fenway Park on Friday night, according to an ESPN.com report.

Giants starting pitcher Matt Cain was placed on the 15-day disabled list Friday with a strained right hamstring, one day ahead of his scheduled start against the Cardinals, according to an ESPN.com report.

The move was made retroactive to May 22, and outfielder Juan Perez was recalled from Triple-A Fresno.

Matt Kemp's time with the Los Angeles Dodgers has become cloudy.

Kemp is hitting .255/.317/.438 and his struggles defensively in center field have led Don Mattingly to play him at the corners.

David Schoenfield of ESPN writes that the Seattle Mariners may be a good fit for Kemp if the Dodgers decide to trade him.

"It makes a lot of sense and the Mariners are the team that should take a chance that Kemp, who turns 30 in September, still has a lot of good baseball left in him," he writes.

The New York Yankees are among the teams showing interest in Kendrys Morales, according to sources.

Morales remains a free agent and once the first day of baseball's amateur draft is complete next Thursday, a club can sign him without losing a high pick.

Mark Teixeira has missed New York's last three games with a wrist injury. Brian McCann was forced to make his first professional start at first base on Wednesday night.

The Yankees are also worried about Carlos Beltran, who is trying to avoid surgery to remove bone spurs in his right elbow.

Cuban right-hander Raciel Iglesias is set to host a showcase for Major League teams in Haiti on Friday, according to reports.

Many clubs are expected to attend.

Iglesias is seen by some as a potential reliever that could make an impact at the Major League level late in the season.

The Boston Red Sox are still hoping they will be able to keep Jon Lester from hitting the open market after the season.

Lester has a 3.45 ERA in the final season of a previous contract extension.

Larry Lucchino told WEEI's Dennis & Callahan that he "certainly expect[s]" to engage in further extension talks with Lester's representatives at ACES before the left-hander becomes a free agent.

The Baltimore Orioles are the "leading team of interest" for Jeff Samardzija ahead of the July 31 non-waiver trade deadline.

There is mutual interest between the Orioles and Chicago Cubs. Baltimore has a lot of young pitching in their system.

The Cubs recently had one of their top talent evaluators at a minor league game in the Baltimore system.
