Fortunately for the Astros, they have an 81-46 record and entered Tuesday with an eight-game lead on the Athletics for first in the American League West. Houston also sports one of the best lineups and pitching rotations in baseball and it can sustain some injuries.Look for Peacock to step into Sanchez’s spot in the rotation. Rogelio Armenteros, Framber Valdez or Jose Urquidy could be replacements, as well.As for Correa, Jack Mayfield is a logical replacement in the short term, but stud prospect Kyle Tucker could get the call, as well, as he has been spending time at first base at Triple-A Round Rock. If he were to play there, it would allow Yuli Gurriel to move to third and Alex Bregman to take over for Correa at shortstop. It was a bad outing, but one that was also notable for its lack of velocity.Sanchez averages 93.7 mph on his fastball this season, but according to Astros Stats, the righty was averaging 91.9 mph in the first inning on Tuesday and 89.3 in the third inning. Clearly, something was wrong.
