Mariners vs Astros MLB Betting Preview
The Mariners (58-66) are looking to take two of three vs. the Astros to keep their slim playoff hopes alive. They're coming off a 10-5 win, where their offense finally came alive.
They're sending out Bryan Woo, who has struggled on the road this season, but looked good in his last outing away from home.
The Astros (63-61) will turn to Hunter Brown in the rubber match against the Mariners on Sunday Night Baseball. Brown has given up three earned runs in each of his last two outings.
But tonight, this sets up as a potential pitcher's duel against Woo.
Mariners vs Astros Pick, Betting Analysis
I'm going with Mariners/Astros Under 7.5. This is a bet on a pitcher's duel between Bryan Woo and Hunter Brown.
Woo has been rolling lately, coming off back-to-back scoreless outings, including one on the road vs. the Yankees. He's deserved better results all year, as his 3.59 xERA is much lower than his 4.15 ERA. When Woo faced the Astros on May 12th, he pitched six innings, allowing only two earned runs.
While Brown has given up three earned runs in each of his last two starts, we all know his ceiling. We saw him pitch seven scoreless innings vs. the White Sox back on July 25th.
Brown has a rock-solid 3.65 xERA so far, inducing ground balls at a high rate of 55.9%. Facing an underwhelming Mariners offense, I like him to turn in a quality start in this spot.
Pick: Under 7.5
