MLB Starting Pitchers & Predictions — Thursday, May 1
Minnesota Twins vs. Cleveland Guardians
- Time/Location: 1:10 p.m. ET at Progressive Field (Cleveland, OH)
- Starting Pitchers: Simeon Woods-Richardson (Minnesota Twins) vs. Ben Lively (Cleveland Guardians)
- Prediction: Twins ML -105
This game likely hinges on how well Simeon Woods Richardson performs on the mound — and he’s positioned for a solid outing. In his last start against the Angels, Woods Richardson allowed just four hits and one run over 5.1 innings, showing strong command.
On the other side, Ben Lively struggled in his most recent outing, surrendering six hits and four runs. Meanwhile, the Twins’ offense is starting to heat up and should give their young right-hander enough run support to work with. Back Minnesota to take care of business and come away with the win.
Arizona Diamondbacks vs. New York Mets
- Time/Location: 1:10 p.m. ET at Citi Field (Flushing, Queens, NY)
- Starting Pitchers: Zac Gallen (Arizona Diamondbacks) vs. Kodai Senga (New York Mets)
- Prediction: Diamondbacks ML +140
The Mets deserve respect at home — they’ve looked like one of the best teams in baseball, and Kodai Senga has backed that up with a strong start, allowing just 21 hits and four earned runs across 28.2 innings. Still, there’s value on the other side.
You're getting plus money with Zac Gallen, a pitcher with All-Star-level talent who’s due for positive regression despite some early struggles over 32.1 innings. Gallen has also had success against this Mets lineup, holding them to a .227 average with 21 strikeouts in 88 at-bats. With the better price and a high-upside arm on the mound, I’ll roll with the Diamondbacks.
