Round Rock had something of a power surge to beat the Zephyrs 6-5 in the series opener Monday night at Zephyr Field.

The loss was New Orleans’ fourth in a row and dropped it into a second-place tie with Round Rock in the Pacific Coast League’s American Southern Division; Nashville taking over first place by a half-game. The victory was the sixth straight for Round Rock.

The Express had six doubles and a homer among their 14 hits. The sixth double, by Jared Hoying in the seventh, gave Round Rock a 6-3 lead.

The Zephyrs cut it to 6-5 in the bottom of the inning on Mark Canha’s single to left, scoring Danny Black from third. Justin Bour followed with a line shot off the glove of second baseman Ryan Rua that scored Jake Marisnick from third. Canha was out at second on the play on a rare 4-8-6 fielder’s choice.

On the way out

When the Zephyrs released reliever Jesus Sanchez (0-5, 7.47 ERA) Monday, it was of little surprise — other than that he was not sent down to Double-A Jacksonville instead.

In Sunday’s series finale at Nashville, he gave up three runs on five hits in 2.1 innings of a 6-4 loss. In the third game of the previous series, at home against Sacramento on June 23, Sanchez entered in the seventh inning of a 2-2 game with two outs and a runner on first base. He walked the first hitter he faced, gave up a single that scored the go-ahead run to the next and was promptly taken out.

In his previous appearance, on June 20 at home against Fresno, he was raked for four runs on four hits while posting two outs.

Sanchez was let go when the Zephyrs took Rett Varner off the disabled list.
