The minor leagues have waived the white flag of unconditional surrender at Long Island's Steven Matz, however, the Mets' top pitching prospect keeps firing.

Matz pitched seven scoreless innings and hit a pair of two-run singles to lead Triple-A Las Vegas over Colorado Springs, 9-1, on Tuesday night.

The Pacific Coast League is a hitter's haven where even the best pitching prospects can look mediocre or worse. But once every five days for Las Vegas, that reputation comes undone.

Tuesday was one of those days as Matz struck out seven hitters and got 12 groundouts, allowing just three hits and a walk.

Matz (6-2, 1.99 ERA) has struck out 68 hitters in 63 1/3 innings this season. His strikeout total leads the entirety of minor league baseball.

The lefthander also went 2-for-3 with two RBIs on Tuesday, bumping his batting average up to .350.

Second baseman Wilfredo Tovar was 2-for-4 with three RBIs, and leftfielder Brandon Allen went 2-for-3 with a double, walk, three runs scored and two RBIs for Las Vegas (29-17, 1st place in Pacific Coast League Southern).
