Odds available at FanDuel Sportsbook at time of publishing.

Houston Astros ML (+108) over Los Angeles Angels

To start off this mega parlay, we’ve got the Astros on the run line. If it’s not broke, don’t fix it. I keep finding ways to bet the Astros, mainly because Houston keeps taking care of business. Not only are they an elite home team, but the Astros’ winning ways have continued away from Minute Maid Park. Wednesday marks a rare occurrence; a game where Houston is actually undervalued. The Astros are short dogs against a struggling Angels squad while starting one of their best pitchers. Cristian Javier was rolling prior to his last start, allowing 5 runs in 5.0 IP against the Royals. Look for the right-hander to bounce back in a big way against an Angels lineup that strikes out a ton.

The Angels are favored because Shohei Ohtani is getting the start. And while Ohtani has been predictably excellent, it still doesn’t make up for the rest of the team’s poor performance. As long as Houston can grab a run or two off Ohtani, the Astros should hold a lead through the first 6 innings. Even if Javier isn’t at his absolute best, the Astros’ bullpen has been one of the best in the majors. I like Houston to start strongly and win another divisional matchup against a clearly inferior team.

Los Angeles Dodgers -1.5 (+114) over St. Louis Cardinals

For the second leg of our mega parlay, we are going with the Dodgers on the run line. LA lost a close contest to the Cardinals on Tuesday, but it’s hard to fade the Dodgers twice in a series. This is especially true with Tony Gonsolin on the mound. Gonsolin has been the Dodgers’ best pitcher this season, posting an ERA of 1.62 through his first 16 outings. In fact, Gonsolin has yet to surrender more than 2 runs in his last 14 starts, while throwing for over 82 innings in that span. LA tends to win when he pitches, and I expect that to be the case once again.

St. Louis will counter with Adam Wainwright, who I believe is being slightly overvalued here. The veteran’s statistical profile is solid but unspectacular, and the Cardinals just won a game in which the Dodgers squandered numerous opportunities against the St. Louis bullpen. LA crushes right-handed pitching, and the challenge should only get tougher for Wainwright with Mookie Betts back in the lineup. I like the Dodgers to lead through 5 innings and win decisively in a bounce-back spot.

Philadelphia Phillies -1.5 (+142) over Toronto Blue Jays

For the final leg of our mega parlay, we are going with the Phillies on the run line. Both of these teams are difficult to figure out, but the decided advantage on the mound lies with Philadelphia. Zack Wheeler has been at his best of late, riding a 14 inning scoreless streak and allowing a grand total of 11 runs over his last 10 starts. With a 2.46 ERA this season and 10.0 K/9 ratio on the road since 2021, Wheeler is in good position to succeed.

While the Blue Jays lineup can mash with the best of them, most of their core has yet to see Wheeler in their young careers. They’ll need to produce some runs for Ross Stripling, as he has the tendency to only pitch 4 or 5 innings. The Blue Jays bullpen has gotten plenty of work of late, and I expect the Phillies to take advantage of that weakness. Back Philadelphia to win comfortably.
