Mayo will start at first base and bat eighth in Sunday's game against the Cubs.

EDGE Analysis

Mayo has been one of the main beneficiaries in the wake of the Orioles' active trade deadline, during which Baltimore shipped out Ryan O'Hearn, Cedric Mullins and Ramon Laureano. The rookie will make a third straight start at first base Sunday, and he could retain a regular spot in the lineup even if Ryan Mountcastle (hamstring) returns from the 60-day injured list during the upcoming week. The Orioles could install Mountcastle as their everyday designated hitter, which would keep first base open for Mayo, who is slashing .241/.389/.517 with two home runs and a 6:6 BB:K since the All-Star break.

Mayo is out of the lineup for Wednesday's game against the Blue Jays.

EDGE Analysis

Mayo will be on the bench for the series finale after he had started in each of Baltimore's last four games while going 4-for-13 with two extra-base hits and a walk. Since getting called up from Triple-A Norfolk on May 31, Mayo has maintained a .749 OPS and has begun to earn more playing time against lefties especially, but Baltimore may need to move another key bat ahead of Thursday's trade deadline in order for the young infielder to gain more of a foothold in the everyday lineup.

Mayo went 3-for-4 with a home run and two RBI in Monday's 11-4 win over the Blue Jays.

EDGE Analysis

Mayo recorded the first three-hit effort of his career, highlighted by a 413-foot solo blast in the second inning. He's impressed since the All-Star break, going 7-for-17 with two homers, five RBI and five runs scored over seven games. The 23-year-old is slashing .240/.318/.406 with three long balls, 14 RBI, 13 runs scored and one steal across 107 plate appearances, and his role moving forward may hinge on what the Orioles decide to do at this week's trade deadline.

Mayo went 1-for-1 with three walks and a run scored in Tuesday's 6-3 loss to Cleveland.

EDGE Analysis

Mayo drew a career-high three walks and logged his second career game with multiple free passes. The resurgence of outfielder Ramon Laureano in 2025 has enabled the Orioles to deploy All-Star Ryan O'Hearn as their primary first baseman in Ryan Mountcastle's (hamstring) stead, which has left Mayo without a clear path to playing time. Mayo is slashing just .205/.283/.301 with one home run, five doubles and nine RBI over 92 plate appearances, and he'll be a candidate to head back to the minor leagues once Mountcastle is healthy.

Mayo went 2-for-6 with a two-run double, a two-run home run and another run scored during Friday's 22-8 win over Tampa Bay.

EDGE Analysis

Mayo finally hit his first major-league home run in the eighth, albeit off shortstop Jose Caballero, who yielded two homers and six runs in the frame. Per Roch Kubatko of MASNSports.com, Mayo is the sixth player since 2020 to hit the first home run of their MLB career off a position player and the first Orioles player to do so since the team moved to Baltimore in 1954. Mayo has three multi-hit games over his last eight starts, and over that span he has gone 8-for-29 (.276) with one home run and seven RBI.

Mayo is not in the lineup for Monday's game versus the Rays.

EDGE Analysis

The Orioles are facing right-hander Ryan Pepiot, marking the fifth straight contest that Mayo has been out of the lineup against a righty. Baltimore will go with Ryan O'Hearn at first base and Jordan Westburg at designated hitter.

Mayo isn't in the lineup for Friday's game against the Angels, Cordell Woodland of 105.7 The Fan Baltimore reports.

EDGE Analysis

After going 0-for-5 with a walk in Baltimore's last series against Detroit, Mayo will take a seat to begin the Orioles' three-game set with the Halos. His absence will put Ryan O'Hearn at first base while Adley Rutschman works as the DH and Maverick Handley starts behind the plate.

Mayo is out of the lineup for Wednesday's game against the Tigers, Jake Rill of MLB.com reports.

EDGE Analysis

Mayo has been seeing semi-regular playing time since being recalled from Triple-A Norfolk on May 31, but he's gone just 4-for-22 with one extra-base hit (a double), a stolen base and a 2:5 BB:K over a stretch of seven games. With the Orioles getting two key position players in Jordan Westburg and Cedric Mullins back from the injured list earlier this week, Mayo could end up being squeezed out of the lineup on a more frequent basis if he's unable to pick up the pace at the plate.

Mayo is not in Saturday's lineup against the A's.

EDGE Analysis

Mayo has been in the lineup for five of Baltimore's last six games since being recalled from the minors. He's gone 3-for-15 in that span but has struck out only three times. Ryan O'Hearn will take over at first base while Adley Rutschman will serve as the designated hitter.

Mayo is not in the lineup for Thursday's contest in Seattle.

EDGE Analysis

Mayo started the first four games for the Orioles upon his promotion from Triple-A Norfolk last week, but he'll get some rest during Thursday's series finale. Ryan O'Hearn is at first base and Adley Rutschman is in the designated-hitter spot.
