Stephenville relied on its pitching and defense in its first two District 8-4A victories, but it was the Yellow Jacket offense that stole the show in Killeen Tuesday night.

Stephenville (14-9, 3-0) erupted for 12 runs in the fourth inning when Dominic Jokel hit a grand slam and Ryan Harper had a 3-run homer, and the Jackets went on to a 17-2 victory over the Kangaroos (7-13, 1-2) in five short innings.

The Jackets sent 16 hitters to the plate in the inning and the first seven all had hits. Harper's 3-run shot ended the hit parade and made the score 12-2.

Jokel's grand slam came seven hitters and two outs later and gave the game its final tally.

Stephenville led 5-2 before it's fourth-inning explosion. Witt Westbrook doubled then scored on a single by Tyler Floyd in the top of the first. Floyd then stole second and scored on a single by Trent Morrison.

Ryan Harper singled, stole second and scored on the first of two doubles by Connor Washington to make it 3-0.

Killeen jumped right back into the game when Jordan Fuentes tripled to lead off the bottom of the first then scored on an infield single by Josh Allen, who went 3-for-3.

Allen stole second, advanced to third on an infield hit then cut Killeen's deficit to 3-2 when he scored on an infield single by Andrew Ramos.

The Jackets added to the lead in the third. Jokel singled and stole second. He advanced to third on a single by Morrison and scored two batters later on Washington's other double to make it 5-2.

Jokel went all five innings on the hill for Stephenville, allowing the two runs on seven hits while striking out four and walking two.

Through 19 innings the Jackets have allowed just two runs on 12 hits in district play.

Stephenville faces Waco Midway, the No. 2 team in the Texas High School Baseball Coaches Association's 4A poll, in a battle of 8-4A unbeatens on Friday. First pitch is scheduled for 7 p.m.
