Rockies right-handed pitching prospect Tyler Matzek struck out nine batters in six innings for Triple-A Colorado Springs. Matzek's well-documented command struggles contribute to his inconsistent results despite electric stuff. Colorado Springs is one of the best hitting environments in the major leagues, and opposing batters are hitting .265/.340/.413 against him for the season. However, he has 61 strikeouts in 66 2/3 innings, and his walk rate has dropped to 4.2 BB/9, which is the lowest level of his professional career.
