SAN ANTONIO — Jecksson Flores hit a grand slam and drove in five runs, but it wasn’t enough as the Storm Chasers dropped a 10-9 decision at San Antonio on Friday.

Flores’ grand slam in the second inning gave the Chasers a 4-2 lead, but the Missions responded with five runs in the bottom of the second, as they stayed in front the rest of the way.

San Antonio pounded out seven extra-base hits in the first four innings to take a 10-6 lead. Travis Shaw and David Freitas hit two-run homers, while Nate Orf added two doubles and a pair of RBIs.

The Chasers pulled within 10-8 in the sixth, as Flores drove in a run with a groundout, and Erick Mejia followed with an RBI single.

Ryan O’Hearn led off the ninth with a home run — his second homer in as many nights. Kelvin Gutierrez followed with a single, was sacrificed to second and moved to third on a groundout. But after a walk, San Antonio closer Taylor Williams struck out Brett Phillips to end the game.

Freitas and Shaw each finished with three RBIs for the Missions, while Cory Spangenberg, who had five RBIs in Thursday’s win over the Chasers, added two hits and scored twice.

San Antonio had all 11 of its hits in the first four innings.

Nick Dini and Phillips, the Nos. 8 and 9 batters in Omaha’s lineup, each scored twice. Dini went 2 for 3 to improve his average to .297, while Phillips has a six-game hitting streak.

Omaha and San Antonio continue their series Saturday at 7:05 p.m.
