What happened: The Tampa Bay Rays and Houston Astros meet again Saturday at Daikin Park after Tampa Bay took Friday's series opener 3-1. The Rays arrive at 52-33 and have now taken nine in a row, while the Astros sit at 43-47 and have dropped two straight.

Why it matters: Tampa Bay is the hottest team in baseball, and the surge that carried the Rays into Houston shows no sign of slowing. For Houston, sitting four games under .500 at the season's midpoint, every dropped series deepens the hole — Friday was a tight pitching duel decided by small margins, the kind of game contending teams find ways to take.

What to watch: The series continues Saturday in Houston, where the Rays will try to stretch their run to double digits and the Astros look to stop the slide before the deficit grows.
