Reyes allows 1 hit in 6 innings for Springfield

Alex Reyes hit double digits for the first time since joining Double-A Springfield.

The Cardinals' No. 1 prospect (No. 20 overall) fanned 10 batters while giving up just one hit in six innings against Frisco in a 7-2 win on Friday night.

Promoted from Class A Advanced Palm Beach in late July, the 6-foot-3 right-hander had not pitched past the 4 1/3-inning mark in four previous Double-A starts. He came into Friday's contest 0-1 with a 5.40 ERA in those games, but found his groove early against the RoughRiders, striking out the side in the first inning.

Reyes has had few bumps since signing in December 2012. The 20-year-old went 2-5 in 13 starts for Palm Beach this year, but managed a 2.26 ERA and has never finished a season with an ERA above 3.62.

He's allowed just 24 earned runs in 86 innings this year, good for a 2.51 ERA in 19 starts across three levels.
