A 10-run outburst in the top half of the fifth inning turned a tight game into a blowout Tuesday as the Rocklin High baseball team routed Oakmont 13-0. The Thunder took advantage of five Oakmont errors in the contest, while banging out 10 hits in the win. As it turned out Rocklin's three first inning runs against Oakmont ace Kory Groves were all the Thunder needed. Senior southpaw Matt Fielding blanked the Vikings on just three hits in a game shortened to five frames by the 10-run mercy rule. Oakmont's Kyle Jones had a double in the game, while Rocklin had three different hitters with a pair of knocks. Austin Diemer, Justin Castro (home run, 3 RBIs) and Trevor McVey (double, 3 RBIs) were the multiple-hit Thunder batters. The win keeps Rocklin (12-4 in the SFL, 19-6 overall) on track to earn a share of the Sierra Foothill League title, as Granite Bay has already concluded its season at 14-4 in league play. If the Thunder can win the next two against the Vikings, they would enter the playoffs as the SFL's No. 1 seed based on a 2-1 head-to-head mark against the Grizzlies. Oakmont (5-11, 10-13) will be at Rocklin at 4 p.m. Wednesday and Thursday to close out its season.
