Ryan Mountcastle

Holliday will slide to shortstop while Gunnar Henderson is out, but hitting ninth is not a great spot for his counting stats. The 21-year-old did hit .333/.407/.458 in 54 plate appearances this spring, so he'll look to carry that over against full MLB pitching staffs. The Orioles complete lineup is: Colton Cowser LF, Adley Rutschman C, Jordan Westburg 2B, Ryan O'Hearn DH, Tyler O'Neill RF, Ryan Mountcastle 1B, Cedric Mullins CF, Ramon Urias 3B, Jackson Holliday SS.

Mountcastle projects as one of the primary beneficiaries of the Orioles making hitter-friendly alterations to the left-field wall at Camden Yards. We're not forecasting a massive power spike, but a return to the 20-homer mark seems much more attainable than it did during Baltimore's dreaded "Walltimore" era.

And so ends Mayo's quest to make Baltimore's Opening Day roster. The 23-year-old top prospect started the spring slowly but had gone 7-for-19 (.368) over his last eight games before being hit in the hand by a pitch on Monday. There isn't a clear path to at-bats in the majors given the Orioles' corner-infield logjam with Jordan Westburg, Ryan Mountcastle, Heston Kjerstad and Ryan O'Hearn all fighting for time. Mayo will head to Triple-A to start the season and may need an injury or a trade in order to get regular big-league playing time.

That's three homers in four days for Mountcastle. The first was hit to right-center, but the last two have been pulled, which is a good sign for someone whose pull rate plummeted after the Orioles moved back the wall in Camden Yards. With the new changes, this still won't quite be the Oriole Park of old, but it should be pretty fair to right-handed hitters.
