Left-hander Hyun-Jin Ryu is expected to be activated to start for the Dodgers on Wednesday night against the Mets, manager Don Mattingly said Sunday. Mattingly conceded that the club will then face a “difficult” roster move to make room for Ryu, who has been on the DL with left shoulder-blade inflammation.

Catcher Matt Wieters, who has been sidelined with a sore right elbow, had a platelet-rich plasma injection in the elbow last Monday, according to Orioles manager Buck Showalter.

Jose Abreu made every effort possible to play through the ongoing pain in his left ankle for at least the past 10 days to two weeks. But watching how much Abreu’s movement was hampered on Saturday pushed the White Sox to put their breakout star on the 15-day disabled list prior to Sunday’s series finale in Houston.

Rangers reliever Alexi Ogando left Saturday night’s 4-2 loss to the Blue Jays with a bruised right hand from a line drive. But Rangers manager Ron Washington said Sunday that Ogando won’t be going on the disabled list.

The D-backs today named Tony La Russa to the newly created position of chief baseball officer. In his role La Russa will report to team president and CEO Derrick Hall, and he will oversee the entire baseball operations department, including general manager Kevin Towers and manager Kirk Gibson.

Samuel Deduno threw six strong innings, and Brian Dozier added to his impressive homer total with a three-run blast in the fifth to help the Twins to a 4-3 win over the Mariners on Saturday night at Target Field.

Jose Abreu left in the seventh inning of the White Sox 6-5 loss to the Astros on Saturday at Minute Maid Park when Paul Konerko pinch-hit for the slugger. Abreu has been bothered by ongoing left ankle soreness, leading manager Robin Ventura to use him at designated hitter for the past eight games.

Alex Cobb (strained right oblique) appears ready to join the Rays’ rotation following his rehab start Saturday in Port Charlotte, Fla., against the Clearwater Phillies.

Astros starter Jarred Cosart struggled with his command through five innings and watched the bullpen hold on for dear life in the eighth on the way to an Astros’ 6-5 win over the White Sox on Saturday afternoon at sunny Minute Maid Park.

The search for a starting pitcher to replace Andrew Cashner in the rotation in time for a start Sunday certainly didn’t qualify as exhaustive or laborious. All manager Bud Black had to do was take a look to his bullpen, as he tabbed rookie Donn Roach to start Sunday against the Rockies after Cashner landed on the 15-day disabled list with elbow soreness.

When your starting pitcher can’t get deep in the game, your bats have to make up the difference. Erstwhile reliever David Phelps threw 100 pitches and completed five innings Saturday, but the Yankees bats backed him with five home runs en route to a 7-1 win over the Pirates.

The Phillies will spend their off-day on Monday afternoon with thousands of fans at Citizens Bank Park for the annual Phillies Phestival, an event which raises awareness and research funds for ALS (Lou Gehrig’s Disease).

The players in the D-backs’ clubhouse don’t expect to interact much with Tony La Russa, who was introduced Saturday as the team’s chief baseball officer, but they were excited about the addition. “The more smart people you can bring into an organization, the better,” pitcher Brandon McCarthy said.

Max Scherzer joined the Tigers four years ago as a fastball-changeup pitcher who had the makings of a nice slider. On Friday, Scherzer threw the Red Sox a curveball, literally. Actually, he threw quite a few of them.

Joba Chamberlain said he actually heard a couple compliments on his beard Friday night from the fans seated behind the Tigers’ bullpen in the right-field seats at Fenway Park. He also heard a fan tell him that UPS was hiring.

On Saturday, Juan Lagares set a rather explosive plan in motion to win his starting job back. Homering, driving in three runs and robbing a home run on defense, Lagares carried Bartolo Colon and the Mets to a 5-2 win over the Nationals.

Dodgers left-hander Hyun-Jin Ryu, who has been on the disabled list with left shoulder-blade soreness, threw a simulated game Friday and played catch Saturday.
