The Baltimore Orioles lead the American League East and are trending toward buying at this year's trade deadline.

One priority for the club could be bullpen help. They lost Felix Bautista to Tommy John surgery last fall and Craig Kimbrel, a free agent addition this offseason, has struggled.

It was reported over the weekend that the Orioles will monitor the status of established closers like Jordan Romano, Ryan Helsley and Ryan Pressly as the trade deadline approaches.

Major League Baseball has agreed to an exclusive, multiyear contract with the streaming company Roku, which will air one game each Sunday this season from now until the middle of September.

Roku's package, branded as "Sunday Leadoff," consists of 18 games starting with this coming Sunday's contest between the St. Louis Cardinals and Boston Red Sox.

Games on Roku can be watched free through the app, on Roku devices or via Amazon Fire, Samsung and Google TVs, among other outlets.

The Chicago Cubs will acquire reliever Tyson Miller from the Seattle Mariners, according to a report.

Seattle will receive Minor League infielder Jake Slaughter.

Miller returns to the Cubs, who used a fourth-round pick on him back in 2016. He has a 3.09 ERA and 12 strikeouts in 11 2/3 innings pitched this season.

Kodai Senga, who has not pitched for the New York Mets this season, is scheduled to throw a bullpen session on Wednesday that could determine how soon he returns to game action.

Senga said that he is overhauling his mechanics as part of his rehab process: "With my current mechanics, I didn't think I'd be able to come back at 100%."

The 31-year-old was shut down in February because of a shoulder strain.

He received a PRP injection and was initially shut down for three weeks. Senga's mechanical reinvention has prolonged his absence.

The Cincinnati Reds have placed T.J. Friedl on the injured list with a broken left thumb.

Friedl suffered the injury when he was hit by a pitch against the San Francisco Giants on Sunday.

In just six games this season, Friedl has batted .182/.250/.227. He had just returned to the Reds a week ago from a fractured wrist.

Rhys Hoskins will undergo an MRI after a hamstring injury forced him to leave the Milwaukee Brewers' game on Monday night in the second inning.

Hoskins said he got hurt while rounding first base as he singled to right field.

Pat Murphy said after the game that Hoskins would have an MRI in the morning.

"It seemed to be like right as I was getting to the turn there," Hoskins said. "I was kind of thinking two out of the box just because of where the ball was placed. I just got into the turn and felt it grab."

San Francisco Giants center fielder Jung Hoo Lee left Sunday's game with a dislocated left shoulder.

Lee made a leaping attempt to catch a fly ball off the bat of the Cincinnati Reds' Jeimer Candelario in the first inning, but the ball hit the top of the wall for a three-run double, while Lee's arm made hard contact with the padding atop the fence. 

Lee will undergo an MRI to determine the extent of the damage.

Austin Riley left the Atlanta Braves' game against the New York Mets on Sunday night early with tightness in his left side.

Brian Snitker said Riley felt a little discomfort during batting practice, but didn't tell anyone on the staff. He spoke up when he felt it again early in the game.

"He was sore," Snitker said. "I just didn't want to take any chances, so we'll look at him again tomorrow and see what's up."

Batting third in the lineup, Riley singled with two outs in the first inning and then struck out swinging in the third. 

Miami Marlins fans are not happy in the wake of the Luis Arraez trade.

A handful of fans protested outside LoanDepot Park prior to Friday's game against the Philadelphia Phillies with fans imploring owner Bruce Sherman to sell the team.

"We are only a few here but the majority of fans are disgusted," said Luis De Armas, a decades-long Marlins fan and the organizer of the protest. "We want to continue coming to the games but not when it remains a losing club. All because of an owner who promised us one thing and did something else." 

After dealing Arraez, Marlins executive Peter Bendix indicated that more deals were on the horizon.

"That's part of the calculation. It's part of the value of the player for the rest of the season when unfortunately our record is what it is, and the fact is that we're unlikely to make the playoffs this year," Bendix said. "Trading that for future value seems like the right thing for this organization right now." 

Shohei Ohtani did not play in the Dodgers' 4-0 loss to the San Diego Padres on Sunday because of back tightness that forced him to exit a game Saturday night.

Los Angeles manager Dave Roberts said sitting Ohtani would be a precautionary measure.
