Julio Urias had his struggles, but continued to run roughshod through the Pacific Coast League, throwing six scoreless innings for Triple-A Oklahoma City against the Sky Sox (Brewers) on Monday afternoon in the high altitude of Colorado Springs.

Urias struck out four and walked three, needing 81 pitches. The Dodgers' top prospect has an active scoreless streak of 16 innings, dating back to April 22.

It is the second straight start Urias pitched six innings, matching his professional high. It was the eighth time he lasted six innings in a start in his career, and was just the 11th time he was allowed to pitch into a sixth inning in 67 games.

He allowed his share of runners to reach base in his two trips through the lineup, allowing four singles, three walks, and hit a batter. The three walks matched the season total for Urias entering Monday.

Urias left the game with Oklahoma City ahead 3-0.

Urias erased the first hit with a double play grounder in the second inning, then picked off Keon Broxton at first base to end the third inning to limit the damage. In the fourth inning, a nine-pitch walk and single to open the frame were erased by a line drive double play to shortstop and a caught stealing.

After allowing just one leadoff hitter to reach base in his first 24 innings of the season, he allowed four leadoff hitters to reach base on Monday, including a double in the fifth inning. But after the double, Urias struck out two to help get him out of the inning, his first punch outs since striking out the first two batters of the game.

At 19 the youngest player in the Pacific Coast League, Urias now has a 1.50 ERA in six appearances this season, including five starts, with 33 strikeouts and just six walks in 30 innings.
