MLB Starting Pitchers & Predictions — Sunday, April 6
Daytime baseball is the best thing about Sundays from now till October. With some of the league's best teams and biggest stars in action today, you can continue to build your MLB bankroll by using our MLB predictions below to the MLB betting promos above. Let's check out two of the marquee matchups on the diamond this Sunday.
New York Yankees vs. Pittsburgh Pirates
- Time/Location: 1:35 p.m. ET at PNC Park (Pittsburgh, PA )
- Starting Pitchers: Will Warren (New York Yankees) vs. Andrew Heaney (Pittsburgh Pirates)
- Prediction: Yankees moneyline -180
If the Pittsburgh Pirates hope to pull off an upset against the New York Yankees, their offense needs to step up—but that's a tough ask. In nine games, the Pirates have failed to score more than four runs in any game.
On the other hand, the Yankees have been held under four runs just once this season, and Aaron Judge has already hit as many home runs as the entire Pittsburgh team combined.
The Yankees are worth laying the juice with today.
Los Angeles Dodgers vs. Philadelphia Phillies
- Time/Location: 1:35 p.m. ET at Citizens Bank Park (Philadelphia, PA)
- Starting Pitchers: Tyler Glasnow (Los Angeles Dodgers) vs. Cristopher Sanchez (Philadelphia Phillies)
- Prediction: Blue Jays ML +110
The Los Angeles Dodgers are going to be favored in many games this season, and it's tough to bet against them after they’ve won nine of their first 10 games. However, the Philadelphia Phillies are one team that can go toe-to-toe with the Dodgers, and they've played well in this series. Christopher Sanchez showed strong form in his season debut and is coming off a solid All-Star season last year.
You won’t often see the Phillies as home underdogs, and you certainly won’t see Sanchez as a dog too often if he continues to pitch like this. Now is the time to take a chance on the Phillies with the plus money.
