Houston Astros vs Tampa Bay Rays Prediction

The Astros have done a good job of rebounding from losses over the last week or so, and Brown is on the mound here. With a 1.43 ERA, 0.83 WHIP, and 67 strikeouts, Brown looks like a CY Young contender. Brown has allowed seven earned runs in his last 50.2 innings. In 56.2 innings, Brown is allowing a .170 batting average, and it drops to a .143 allowed batting average in 91 at-bats against left-handed hitters. It’s filthy, folks. It doesn’t matter what you think of Bradley or the Rays as a team. I’m not stepping in front of the Astros with Brown on the mound. The price is reasonable. Give me the Astros.
