Wisler, ranked No. 69 on the Top 100, held Las Vegas to one unearned run on five hits and four walks in 5 2/3 innings. He struck out one batter and threw 96 pitches.
Syndergaard and Wisler first faced off May 16 in El Paso. Syndergaard picked up the victory in that game as the 51s won, 10-2. Both Syndergaard and Wisler have improved since then and Friday's game did a better job living up to its billing as a pitchers' duel.
Syndergaard had mixed results in the first half of the season, but has regained his overpowering demeanor in the last month. In his last five starts, he is 2-1 with a 2.76 ERA and 33 strikeouts in 29 1/3 innings. After making two quality starts in his first 15 starts, Syndergaard has three in that stretch.
Wisler began his season at Double-A San Antonio and was promoted to El Paso in May. After a rough introduction to the PCL, he has adjusted and is 6-1 with a 3.77 ERA and 57 strikeouts in his last 13 starts.
