A midweek series between the Houston Astros and Detroit Tigers could have postseason seeding implications, starting with today’s opener at 6:40 p.m. ET in Comerica Park on MLB TV. My Astros vs. Tigers prediction finds value in the road team.

The Tigers, have the edge over the Astros for a bye as the No. 2 seed, enter this matchup as -155 moneyline favorites. But I recommend fading Detroit starter Jack Flaherty in my Astros vs. Tigers best bet.

Our Astros vs. Tigers prediction gives a slight edge to Detroit, but the betting value is on Houston. Ballpark Pal’s model projects the Tigers to win by a score of 4.55 to 4.41, giving the hosts a 53.2% chance of victory.

Detroit enters with better form, having won five of the last seven against the bottom of the American League Central division. Houston is coming off a 5-4 stretch against three AL East foes.

However, Flaherty has underwhelmed in his past two starts, giving up 10 earned runs on 16 hits. That’s why we believe in the value of Houston’s moneyline price as our Astros vs. Tigers best bet, particularly at +120 or better in a coin-flip matchup.

If you don’t feel comfortable backing Houston’s moneyline value, our Astros vs. Tigers player prop offers a similar chance to fade Flaherty.

Flaherty is 6-12 with a 4.76 ERA, allowing three or more runs in three of his previous five outings. He’s lost the ability to place his fastball, with his Location+ dropping from 103 to 98 since last year. That’s why his walk rate has increased from 5.9% to 9.2%, resulting in significantly worse overall numbers.

Considering the Astros rank 11th in on-base percentage this year, it could be a long night if Flaherty’s command is down once again on Monday.
