Here are this week's rankings:
1. Houston Astros (44-20 overall record, No. 1 ranking last week) -- Ace Dallas Keuchel's neck issue makes it more imperative they trade prospects for a big-time arm at the deadline.
2. Washington Nationals (38-24, No. 2) -- Injury to relief pitcher Koda Glover means the bullpen issues won't be solved without adding an important high-leverage arm.
3. New York Yankees (37-23, No. 4) -- Did you see what they did to the Orioles? A 38-8 beat-down in a three-game sweep. Day-by-day, they keep proving they are for real.
