Justin Steele pitched three-hit ball into the sixth inning in his fourth straight win, and the Chicago Cubs beat the San Diego Padres 6-0 on Tuesday.

Yan Gomes had four of Chicago’s seven hits, including a two-run drive off Blake Snell in the second. The veteran catcher is batting .441 (15 for 34) with four homers and nine RBIs in his last eight games.

The game-time temperature was 41 degrees, and the wind made life difficult on a handful of plays throughout the game. But nothing seems to faze Steele these days.

The 27-year-old Mississippi native struck out five and walked two in 5 1/3 innings. San Diego had at least one baserunner in four of the first five innings, but it came up empty each time.

Steele (4-0) improved to 5-1 with a 1.07 ERA in his last 12 starts dating to July 22. He pitched at least six innings and allowed two or fewer runs in each of his first four outings this year.

The Cubs broke it open with four runs in the eighth. Gomes hit an RBI single and scored on Nico Hoerner's three-run triple.

Snell (0-4) allowed four hits, struck out five and walked five in his third straight loss. The veteran lefty has 18 walks in 23 innings on the season.

San Diego, which had won four of five, finished with five hits. It went 0 for 8 with runners in scoring position and left 10 runners on base.

After Steele retired Juan Soto for the first out of the sixth, Adbert Alzolay, Mark Leiter Jr., Keegan Thompson and Michael Rucker combined for 3 2/3 innings of two-hit ball.

Chicago has five shutouts through 22 games for the first time since 1969, matching a modern franchise record.

San Diego right-hander Michael Wacha and Chicago left-hander Drew Smyly take the mound on Wednesday night. Wacha (2-1, 7.08 ERA) was tagged for five runs and 10 hits in four innings in a no-decision at Arizona in his last start. Smyly (2-1, 3.13) is coming off a dominant performance against the Dodgers, striking out 10 in 7 2/3 innings in a 13-0 win on Friday.
