Let’s dive into our three-leg parlay, featuring the Phillies, Tigers and Mariners  at +296.

Phillies vs. Rockies (3:10 PM, EST)

Phillies Moneyline (-298) at FanDuel Sportsbook

The Phillies will face the Rockies, who is the worst team in MLB. They can make the White Sox look good most nights of the week. 

The Rockies have won just eight games and things seem to be getting worse as the season develops. 

Philadelphia is 30-18 leading NL East by 1.5 games. Ranger Suarez will get the start for the Phillies, and he is 2-0 in 172 innings this season. 

The Rockies are going with German Marquez who is 1-6 with an 8.78 ERA. He has been brutal in 2025 and the Phillies should take advantage of this mismatch. 

Philadelphia has the third best team batting average in baseball at .264 and Trea Turner is a big reason for their success. He is hitting .305 to go with 58 hits and 17 RBIs. 

I expect Philadelphia’s offense to score consistently and coast to a victory on Thursday.

Guardians vs. Tigers (6:40 PM, EST)

Tigers Moneyline (-142) at FanDuel Sportsbook

A pair of AL Central teams square off in a big division game between Cleveland and Detroit. The Tigers currently lead the division by five games with a 33-17 recprd. 

The Guardians are in fourth place at 25-22, and they have some ground to overtake. They are 3-7 in their last ten games. 

Cleveland will start Slade Cecconi who has pitched just five innings in 2025. He has a 5.40 ERA, and allowed three runs in his only start of the year against the Reds. 

Jack Flaherty will toe the rubber for Detroit with a 4.44 ERA. He is a solid pitcher that doesn’t have the numbers to show for in 2025. 

The Tigers are hitting .260 which is the sixth best in baseball. This is a big reason why Detroit is the best team in the American League currently

We expect the Tigers to stay hot at the plate and take advantage of a pitcher that only has five innings on the year in Cecconi.

Mariners vs. Astros (8:10 PM, EST)

Mariners Moneyline (-135) at FanDuel Sportsbook

George Kirby will take the mound for the first time this season. He has been battling an injury and is finally ready to pick up where he left off in 2024.

Kirby went 14-11 to go with a 3.53 ERA in 2024. Houston is starting Lance McCullers Jr. who has a 7.88 ERA in eight innings this year. 

He has yet to make it past the fourth inning in three starts this season.

McCullers went a third of an inning allowing seven runs on three hits against Cincinnati on May 10. If he repeats a similar performance, it’s going to be a rough season.

Seattle hasn’t been swinging the bats well at the plate, but they have an advantage on Thursday against the struggling McCullers.
