St. Louis starting pitcher Carlos Martinez took a no-hitter into the seventh inning and the River Walkers rode a three-run top of the fourth inning to a 4-2 win over the Des Moines Harvesters at LaBlatt Stadium.
Martinez did allow a run without a hit in the fourth inning, when A.J. Pollack was hit by a pitch to open the frame.
Pollack stole second, moved to third on a ground out and scored on a Rafael Devers sacrifice fly.
That run cut a St. Louis lead to 3-1.
The Harvesters first hit came in the seventh, on a lead-off single from Kolten Wong.

A wild pitch moved Wong to second, and he scored when Devers doubled.

That made it 4-2, and it ended Martinez day.
In his six innings, Martinez allowed the two runs on two hits. He struck out four and walked one.
Michael Conforto had an RBI single and Nicky Delmonico plated two with a single in a three-run fourth inning against Des Moines' Drew Pomeranz.
Rhys Hoskins took Pomeranz deep in the fifth inning for his 22nd homer, putting the Walkers up 4-1.
St. Louis needed to shuffle through six relievers to close out the victory.
Three pitchers (Jerry Blevins, John Curtiss and Jake Diekman) all got an out apiece in the seventh inning.
Chaz Roe got the first out of the eighth before running into trouble again, allowing a double to Thairo Estrada and walking Pollack.
But Andrew Miller came on to stifle the rally. He also got the first out of the ninth before Brad Boxberger came on to earn his second save of the campaign.
