The Baltimore Orioles and New York Yankees opened a three-game weekend series at Camden Yards on Friday night as the American League East’s two early front-runners separated themselves from the field, while the defending World Series-favorite Los Angeles Dodgers cooled in Philadelphia and the slumping Houston Astros began, tentatively, to settle.

Baltimore entered Friday at 7-1, the best mark in baseball, after sweeping a midweek two-game set against the Tampa Bay Rays at home on Wednesday and Thursday. The Yankees, at 6-3, arrived having taken five of their last six and looking to regain ground in a division that has already produced three of the league’s hottest starts. Right-hander Gerrit Cole drew the start for New York; the Orioles countered with 22-year-old Cade Povich, whose seven shutout innings against Toronto on opening week have made him the early surprise of manager Brandon Hyde’s rotation.

“They’re playing the way we knew they could play, and they’ve added pieces,” Yankees manager Aaron Boone told reporters in the visitors’ clubhouse Friday afternoon. “We don’t change anything. We came up here to win a series. That’s the only number that matters this weekend.”

The Orioles’ run has been built on a rotation that has produced a 2.18 ERA through eight games and on the early MVP-caliber performance of catcher Adley Rutschman, who is hitting .400 with three home runs and a 1.143 OPS. The trade for Miami left-hander Jesús Luzardo, brought in by general manager Mike Elias in December, has so far delivered the front-of-rotation arm Baltimore lacked at last year’s deadline. Luzardo struck out 10 over six and one-third innings against the Rays on Wednesday.

In Los Angeles, the Dodgers’ 5-1 start has flattened. A four-game series in Philadelphia opened Thursday night with a 6-3 loss in which the Phillies battered Tyler Glasnow for five earned runs across four innings — the right-hander’s shortest outing since June 2024. Manager Dave Roberts said after the game that Glasnow’s fastball command “was not where it has been” and that the team would not adjust the rotation order on the basis of one outing.

The Phillies, who entered the series 4-3, have built their early identity around a deepened bullpen and the return of left-hander Cristopher Sánchez from offseason elbow rehabilitation. Sánchez threw two scoreless innings of relief Thursday and is expected to slot back into the rotation by the third week of April. Manager Rob Thomson, asked Friday whether the early-season win signaled a shift in the National League East pecking order, demurred.

“It’s April 10,” Thomson said. “Ask me again on May 10. We feel good about who we are. That’s as far as I’ll go.”

Sota Murakami, the Dodgers’ $148 million Japanese free-agent signing, has continued to produce: he homered in the eighth inning Thursday for his fourth of the young season and is hitting .417. But the wider offense, which scored 41 runs across its 5-1 homestand, has gone quiet against Philadelphia, and Roberts conceded that left-handed pitching, long flagged as a potential vulnerability for the new third baseman, will continue to be tested through the spring travel schedule.

In Houston, the Astros snapped a four-game losing skid Wednesday with a 5-2 win over the Texas Rangers and added a 7-4 victory Thursday in which right-hander Hunter Brown threw six innings of one-run ball. The club’s bullpen reshuffle, which moved Bryan Abreu into a stricter setup role earlier in the week, has tightened a unit that issued nine walks across the first weekend in Arlington. Houston enters the weekend at 3-5 and will host the Seattle Mariners beginning Friday night.

The New York Mets, meanwhile, remained the league’s most prominent disappointment. After an 0-4 start, the club has won two of three but will play the next month without shortstop Francisco Lindor, whose left oblique strain is now expected to require closer to four weeks of recovery, according to a club source not authorized to speak publicly about the timeline. Manager Carlos Mendoza on Thursday declined to confirm the longer absence but said the team’s internal projections had been “adjusted.”

The Pittsburgh Pirates’ Paul Skenes drew the largest non-Friday-night television audience of the early season Wednesday, when his 13-strikeout performance against the Chicago Cubs at PNC Park aired on a national broadcast window. Skenes, whose average four-seam velocity has crept to 99.6 mph in his first three starts, is being managed on a strict innings plan that pitching coach Oscar Marin said would not change “regardless of what the standings look like in July.”

The new automated-challenge ball-and-strike system, in its second week of regular-season use, continued to draw scrutiny. Through Thursday’s games, league data showed the overturn rate had settled to 36 percent, and average game length had risen by an estimated 80 seconds compared with the same date in 2025. The competition committee, which is scheduled to review the system at the end of May, has so far not signaled any midseason changes.

“It’s working roughly as the projections said it would,” said Karim Doyle, a baseball operations analyst with the Strategic Game Group in Boston. “The interesting question isn’t whether the technology works. It’s whether the way catchers are choosing to use challenges starts to reshape framing incentives over a full season. That’s a 2027 conversation, not a 2026 one.”

For the weekend, the focus narrows to Baltimore, where a sold-out Camden Yards will offer the season’s first marquee divisional test. The Orioles travel to Yankee Stadium next weekend for a rematch, and Hyde said Friday morning that his rotation order would be set after Sunday’s game. The Dodgers and Phillies continue their four-game set through Sunday, and the Astros open a three-game series against Seattle on Friday night.

Major League Baseball officials said updated attendance and viewership figures for the season’s opening fortnight would be released early next week.
