Berrios, Allard among top prospect performers Sunday

After he allowed six runs (three earned) on nine hits over 5 2/3 innings in his last start, Jose Berrios rebounded in a big way Sunday as he fired six scoreless innings, yielding four hits and two walks, to help lead Triple-A Rochester past Norfolk, 3-2.

Berrios, No. 15 on the Top 100, struck out the side in the first inning en route to fanning nine hitters in the outing, which saw the Twins' No. 1 prospect throw 64 of his 95 pitches for strikes.

The performance was the latest in what has been a series of strong outings for the 22-year-old right-hander. Since his start on June 23, Berrios has posted a 0.86 ERA while striking out 45 hitters in 41 2/3 innings across his last six turns for Rochester.

Berrios is 9-4 in 14 starts for the Red Wings, with 2.42 ERA and a 94-32 strikeout-to-walk ratio in 89 1/3 innings.
