The 14-15 Orioles, fighting for AL East positioning, counter without RHP Dean Kremer (quad strain), INF Jackson Holliday (hand), and 1B Ryan Mountcastle (60-day IL), but leverage home-field edge and recent momentum against a banged-up Astros rotation featuring Lance McCullers Jr., prone to home runs. Weather holds fair for game 2, with both bullpens tested by short turnarounds.
