The Tampa Bay Rays have steamrolled teams at The Trop all season, posting a remarkably strong 48-25 record on home soil.
Their high-end contact skills and speed play very well indoors and will make it difficult for a feast-or-famine Houston Astros offense to keep up.
Let's break down my Astros vs. Rays predictions and MLB picks.
Who will win Astros vs Rays today: Tampa Bay Rays (58%)
For help understanding probabilities, see our odds calculator.
I’m on the Tampa Bay Rays up to 60%.
Ian Seymour is rocking a matching 2.69 xFIP and SIERA with a 30.3 K% over the past 30 days. The numbers under the hood are excellent and give him a strong chance of limiting the Houston Astros.
I’m not as sold on Peter Lambert. He has allowed 1.58 baserunners per inning over the same stretch while his xFIP and SIERA sit closer to 5.0.
Lambert also owns a 5.05 xERA over six starts against Top-10 opponents in OPS vs. RHP, and the Rays come in at No. 5.
COVERS INTEL: Peter Lambert's 4.60 SIERA over the past month ranks him 22nd among today's projected starters, and well below 1st-ranked Ian Seymour.
Astros vs Rays Over/Under pick: Over 7.5 (56%)
I like the Over to 55%.
Lambert sits in the 23rd percentile in ground ball rate this season. He struggles keeping the ball down, and the Rays excel at stringing together hits and slapping it all over the field.
While Seymour’s pitching profile is mostly strong, he is vulnerable against power. He’s in the 12th percentile in limiting barrels and has paid the price of late, allowing 2.09 home runs per nine innings over his last 10 starts.
The Astros rank fifth in homers this season and have the power to capitalize.
Astros vs Rays home run prediction: Junior Caminero (27%)
It’s arrows up for Junior Caminero.
The powerful righty has seen all his indicators spike against Lambert’s pitch mix over the last 25 at-bats. His average exit velocity is up almost four miles per hour, his barrel rate is up over 10%, and his hard-hit rate has soared to 66.7%.
He is consistently making powerful contact, and there’s no easy way for Lambert to avoid it in this game.
Caminero has managed an ISO of .250 or higher against each of Lambert’s four most-used pitches.
