The Washington Nationals recalled from rehab and reinstated outfielder Denard Span from the 7-day disabled list and optioned outfielder Steven Souza Jr. to Syracuse on Saturday.

Major League Baseball and the Players Association are reportedly discussing possible tweaks to rules involving home-plate collisions and transfer plays. MLB made it clear when the changes were introduced that adjustments were likely to be necessary.

Every lineup, every day, as they are made public by the clubs.

The A’s showed no mercy to their Friday night houseguests, scoring seven times off the Astros in the first inning, more than enough runs for Sonny Gray to play with in an 11-3 victory in the three-game series opener.

Troy Tulowitzki launched a three-run homer to right-center, and didn’t stop until he had three hits, including a double, and five RBIs in a 12-1 Rockies victory at Coors Field on Friday night.

Only a high pitch count prevented Aaron Harang from bidding for history on Friday night at Citi Field. But after he’d delivered seven hitless innings, the Braves preserved his gem with a late-inning eruption that allowed them to cruise to a 6-0 win over the Mets.

Howie Kendrick hit his first two home runs of the season and drove in four runs to pace the visiting Angels to an 11-6 victory over the Tigers at Comerica Park on Friday night. Albert Pujols hit his 497th home run and right-hander Jered Weaver earned his first win.

The Rays erased a four-run deficit against the Yankees on Friday night to take an 11-5 win at Tropicana Field. With the victory, the Rays snapped a four-game losing streak while moving to 8-9 on the season.

Someday, Brewers backup catcher Martin Maldonado will be able to gather his grandchildren and tell them about the night he knocked the cover off the baseball.

The way the Nationals played on Friday night was the antithesis of how they played the previous night. They played much better defense and Gio Gonzalez pitched his best game of the season as the Nationals defeated the Cardinals, 3-1.

The Rangers, behind the pitching of Martin Perez, recorded their fifth shutout of the season, as well their fourth consecutive victory, with a 12-0 pounding of the White Sox on Friday night.

Giancarlo Stanton rocked Marlins Park on Friday night and received a water bath in the process. Stanton blasted a grand slam in the ninth inning to propel the Marlins to an 8-4 win over the Mariners. The dramatic drive came off Yoervis Medina with no outs. Stanton spiked his helmet prior to reaching home and was then doused with water by his teammates as he touched the plate.

With Thursday night’s loss to the Yankees — a defeat that included hitting into a triple play — in the past, the Rays must pick up the pieces and rebuild their season.

David Ross went the other way for an RBI double down the line in right with one out in the top of the ninth to snap a tie and lead Boston to a 3-1 victory on Thursday night in the rubber match of a three-game series against the White Sox.

Cold weather is, of course, largely a state of mind, especially when you have the option of being indoors.

Denard Span played in his first rehab assignment for Class A Hagerstown and went 1-for-2 with two walks, three runs scored and an RBI. Span is on the seven-day disabled list due to a concussion.

James Shields led Kansas City to a 5-1 win over Houston at Minute Maid Park on Thursday, completing a three-game sweep of the Astros.
