Astros have dropped the first two games (5-3 and 10-3 losses), going 3-7 in their last 10 amid injuries to SS Jeremy Peña (hamstring, mid-May return), pitchers Hunter Brown and Cristian Javier, thinning their rotation and infield. Probable starters Lance McCullers Jr. (1-2, 6.75 ERA) and Chris Bassitt (1-2, 6.75 ERA) both struggle early, while Yordan Alvarez's 11 HR pace power for Houston against Baltimore's middling 4.93 runs allowed per game. Orioles' even 5-5 recent form and key bats like Adley Rutschman (.345 AVG) bolster trader consensus toward a competitive interleague clash.",
