Roy Halladay threw a bullpen session on Saturday to follow up Thursday’s rehab start with the GCL Phillies, and pitching coach Rich Dubee deemed both outings “fine.”

Returning from the disabled list with six weeks left to prove he belongs atop the Brewers’ starting rotation, Yovani Gallardo delivered 6 1/3 innings in a 2-0 win against the Reds at Miller Park, where 37,046 fans got a glimpse of an Opening Day starter intent on a late-season surge.

Mets pitcher Jenrry Mejia left Saturday night’s 8-2 loss to the Padres with the score tied at 1 in the fourth inning because of a sore right elbow, which could ultimately end his season.

An attorney for Alex Rodriguez voiced numerous claims in a wide-ranging interview with The New York Times, among them that the Yankees supposedly concealed the results of an MRI that showed Rodriguez was injured during last year’s postseason.

Dustin Pedroia was removed for the final half-inning of Saturday’s 6-1 win against the Yankees after taking a foul ball off his left shin, but manager John Farrell said he has no reason to expect his second baseman will miss any game action.

There remains just one team in the Majors that hasn’t endured a four-game losing streak this season — the Boston Red Sox. John Lackey made sure of that on Saturday afternoon at Fenway Park when he put together his best performance in a few weeks, snapping Boston’s three-game skid with a 6-1 victory over the Yankees.

With six scoreless innings, Joe Kelly helped the Cardinals to a 4-0, series-evening win over the Cubs on Saturday. A two-run homer by catcher Yadier Molina and heads-up baserunning by Jon Jay punctuated the victory in front of 41,981 fans at Wrigley Field.

The D-backs banged out seven consecutive two-out hits en route to a six-run third inning and a 15-5 win over the Pirates on Saturday afternoon in front of a sold-out crowd at PNC Park.

Instead of making his scheduled start on Sunday, Bartolo Colon will be placed on the 15-day DL with a left groin strain, an injury that initially surfaced during his Friday flat ground session. Tommy Milone will be recalled from Triple-A Sacramento to start in his place against the Indians.

Ryan Braun placed calls on Friday to a number of uniformed and non-uniformed Brewers personnel, the beginning of an apology tour that multiple clubhouse sources said would go public in the very near future.

Royals infielder Miguel Tejada, the 2002 AL MVP Award winner, was suspended 105 games without pay Saturday after testing positive for an amphetamine in violation of MLB’s Joint Drug and Prevention Program.

Alfonso Soriano chuckled as a pack of reporters approached his locker in the cramped Fenway Park visiting clubhouse on Friday evening, eager to discuss the continuation of a historic hot streak.

Clay Buchholz had his most intensive bullpen session yet during his recovery, as hitters stood in the box during a 60-65 pitch session before Saturday’s game against the Yankees.

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

Justin Maxwell was scheduled to go on bereavement leave from the Royals after Friday’s first game of the day-night doubleheader against the Tigers. Left-hander Will Smith has been recalled from Omaha and will be eligible for the Friday night half of the doubleheader.

Danny Duffy had a no-hitter going for 5 2/3 innings and wound up the winner as the Royals beat the Detroit Tigers, 2-1, in the first half of Friday’s day-night doubleheader.

Slowly but surely, Bruce Rondon is maturing into a reliable Major League reliever. In the process, the Tigers are developing a potentially major piece to their late-season bullpen.
