Lefty Rob Zastryzny completed five perfect innings in last start
The Cubs selected LHP Rob Zastryzny in the second round of the 2013 draft. And three years later, Zastryzny appears to be putting it together with Triple-A Iowa.
During what has been a challenging season for the pitching prospects in the Cubs’ system, Zastryzny had the best start of his pro career his last time out.
Rob Zastryzny completed five perfect innings against the Omaha Storm Chasers on Monday at Werner Park. Zastryzny struck out eight and made 69 pitches, 45 for strikes, to 15 batters.
Rob Zastryzny struck out eight, or more than half, of the 15 batters he faced. And the other seven outs were all on the ground. Iowa won in blowout fashion 13-0.
Zastryzny started the season with Double-A Tennessee and was bumped up to Iowa after only nine starts with mixed results. Zastryzny was 3-2 in nine starts with a 4.28 ERA and 1.28 WHIP with the Smokies. Zastryzny allowed 29 runs, 26 earned, on 50 hits with 20 walks and 42 strikeouts in 54 2/3 innings.
The Cubs promoted Zastryzny to Iowa on May 24 and he struggled in June. Zastryzny was 3-1 in five starts with a 5.59 ERA and 1.45 WHIP.
Rob Zastryzny has been really good in each of his last two starts. Before the five perfect frames in Omaha, Zastryzny tossed four scoreless innings in New Orleans.
In his last four games, three starts, Zastryzny is 1-1 with a 2.81 ERA and 1.06 WHIP. Zastryzny has allowed six runs, five earned, on nine hits with eight walks and 16 strikeouts in 16 innings.
Rob Zastryzny is 5-3 in 13 games, 12 starts, with a 4.37 ERA and 1.26 WHIP for Triple-A Iowa. In 70 innings, he’s allowed 37 runs, 34 earned, on 59 hits with 29 walks and 63 strikeouts.
Granted the last two starts are a very small sample size but Zastryzny has always had the stuff. It’s been command and consistency he lacked. A strong finish to the season for Rob Zastryzny would be good for the organization with a 40-man roster decision looming, but more importantly a very positive step in his development.
