What happened: The Baltimore Orioles head into Sunday's series finale against the Houston Astros holding a 2-0 series lead, built on one-run and two-run wins over the past two days. Baltimore has won five straight games overall, while Houston enters at 44-47 having dropped four of its last five.

Why it matters: Baltimore's streak comes as general manager Mike Elias has signaled the Orioles will look to buy ahead of the Aug. 3 trade deadline, and continued wins strengthen that case. Houston, already reshaping its roster after dealing pieces to Milwaukee this week, is trying to avoid a third straight series loss to Baltimore.

What to watch: First pitch is scheduled in Houston, with Baltimore looking to extend its win streak to six games and Houston aiming to avoid dropping the series.
