Thursday Pebble Report: Roy Oswalt brings the heat

Triple-A Colorado Springs - L 6-25 (30-21)

Chris Volstad and the rest of the Sky Sox pitchers struggled to contain the Rainiers offense on a day when Mike Zunino, the Mariners top prospect, had the day off. Volstad lasted only into the third inning when he was pulled with 11 runs and 12 hits allowed. The Sky Sox relievers did little to contain the bleeding, allowing an additional 14 runs to cross home plate.

First baseman Ben Paulsen doubled in the second inning and later scored on a Greg Golson single. Matt McBride hit his 11th home run of the season and Josh Rutledge added his first at the Triple-A level. Corey Dickerson (#7 PuRP) doubled and scored on a 1-for-5 night.

Double-A Tulsa - W 16-1 (23-28)

Kiel Roling, Kent Matthes and Kyle Parker (#4 PuRP) all homered for Tulsa in Roy Oswalt's first win as a Driller. The win snapped a five game losing streak for the Drillers. Tulsa racked up 16 hits in a rout of the Oakland A's affiliate, including two from center fielder Rafael Ortega (#9 PuRP).

Former Houston Astro Roy Oswalt enjoyed his best start in the Rockies organization, completing six innings and allowing only one earned run on three hits. Oswalt had six strikeouts and walked a single batter.

High-A Modesto - L 5-9 (24-28)

Designated hitter Ryan Casteel continued his hot hitting, getting a double and a home run. It was Casteel's fourth home run in his last five games, which garnered four RBI for Ryan on the night. Catcher Will Swanner (#5 PuRP), hitting out of the third spot for this game, had a pair of hits including a double. Swanner has finally pushed his average above .200 for the season and has a .902 OPS in his last 10 games.

Starter Ben Alsup suffered through his worst start of the season, allowing eight runs to the Diamondbacks affiliate. Alsup permitted five extra base hits, including two home runs to Arizona's No. 19 prospect Jake Lamb.

Low-A Asheville - L 12-5 (28-23)

Starter Shane Broyles endured one of his worst starts of the season, allowing seven runs on nine hits. Shane struck out two and issued three walks. Twenty-third round pick Andrew Brown made his Low-A debut in Asheville and went 1.2 innings, allowing two earned runs on three hits.
