Round Rock, Tex. - Martin Perez tossed a complete game gem, allowing just one unearned run as the Round Rock Express (60-70) squeaked by the Oklahoma City RedHawks (68-61) 2-1 before 8,085 Monday night at The Dell Diamond.

Perez (7-6) was phenomenal, using 97 pitches to go the distance, 71 of which were strikes. He allowed six hits and struck out seven. For just the third time in 20 games with Round Rock this season, Perez did not allow a walk.

The lefty held the RedHawks 1-for-10 with runners in scoring position. He worked around leadoff doubles twice. Possibly the most impressive part of his start was that he only needed 18 pitches to get through the final three innings.

For the season, Perez is now 3-0 in three starts against the RedHawks. He has allowed one run over his last 16 innings and just two runs over his last 21 innings when facing Oklahoma City.

For the third straight night, the Express scored in the first. With one out, Luis Hernandez and Matt Kata knocked back-to-back doubles to make it 1-0. Hernandez's double extended his current hitting streak to 16 games.

With none on and two out in the fifth, the Express notched three straight hits to add to the lead. Brandon Snyder doubled, Koyie Hill singled, and Julio Borbon sent a double to shallow left field to give Round Rock a 2-0 lead.

The RedHawks were able to score for the first and only time in the sixth. Jimmy Paredes sent a line drive off Perez's leg that deflected into shallow right field, scoring Carlos Corporan from second base.

In the seventh, the RedHawks had a great chance to tie, but Perez was able to keep them off the board. Hessman led off with a double and was sacrificed to third by Matt Dominguez. Jose Martinez flied out to shallow right field, not deep enough for Hessman to try and tag up. Marc Krauss then grounded out to end the inning.

On most nights Brett Oberholtzer's outing would have been good enough for a win, but he ended up with a tough loss. Oberholtzer (5-6) allowed two runs over 7.2 innings, a new high since joining the RedHawks. He scattered 10 hits, walked one, and struck out seven.

The RedHawks still have a chance to win the series when they face the Express at 7:05 p.m. Tuesday night at The Dell Diamond. Live coverage begins at 6:35 p.m. on AM 1340 The Game, 1340thegame.com, or through the free IHeartRadio mobile app.
