Martes rebounds in second Double-A start

It has been quite the full-season debut for Francis Martes.

The Astros' No. 7 prospect dominated in his second Double-A start on Wednesday, striking out nine batters in six scoreless innings as Corpus Christi defeated Frisco, 5-0. He scattered five hits and three walks in the outing, throwing 57 of 99 pitches for strikes.

The outing was a resounding success for the 19-year-old right-hander after a shaky Double-A debut last week in which yielded six earned runs on seven hits in 4 2/3 innings for the Hooks.

Acquired from the Marlins at the 2014 Trade Deadline, Martes excelled for Class A Quad Cities during the first half to the tune of a 1.08 ERA, 0.88 WHIP and 45/13 strikeout-to-walk ratio in 52 innings (10 appearances/eight starts) before moving up to Class A Advanced Lancaster in late July.

He was equally impressive during his brief stay in the hitter-friendly California League, going 4-1 with a 2.31 ERA with 37 strikeouts in 35 innings (six appearances/five starts) for the JetHawks.

With Wednesday's outing, Martes has now fanned at least nine batters in a single game at three different levels. He struck out a season-high 10 batters twice this season, accomplishing the feat for both Quad Cities and Lancaster.

On the season, Martes is 8-3 with a 1.94 ERA, 1.06 WHIP and 94/27 strikeout-to-walk ratio in 97 2/3 innings across three levels.
