SAN DIEGO (AP) — David Eckstein doubled in Tony Gwynn Jr. from first base with two outs in the eighth inning to break a scoreless tie, leading Mat Latos and the San Diego Padres over the Houston Astros 3-0 on Friday night.

Latos (9-4) won his fourth straight decision, holding Houston to four singles and striking out seven, with no walks, in eight innings. He improved to 8-1 with a 1.62 ERA in his last 11 starts, a run that started with a 7-0 win at Houston on May 7. It was San Diego's 11th shutout, tying the New York Mets for the big league lead.

Houston's Roy Oswalt also struck out seven while holding San Diego to three singles and two walks in seven innings.

Astros reliever Brandon Lyon (5-2) came on to start the eighth and retired Everth Cabrera and Matt Stairs, who was pinch-hitting for Latos. Gwynn singled to left and came around on Eckstein's double into the left-field corner.

After Adrian Gonzalez was intentionally walked, Tim Byrdak came on and walked Chase Headley before allowing Scott Hairston's two-run single to left. Headley overran second base and was thrown out.

Heath Bell pitched a perfect ninth for his 22nd save in 25 chances.

Latos has held Houston scoreless in 16 innings this season, with 16 strikeouts and no walks.

Oswalt came in with a 10-2 record against San Diego. He has allowed three or fewer runs in 13 of his last 15 starts against the Padres.

He also came in receiving the fourth-lowest run support in the majors at 2.94 runs per game.

Oswalt retired the first 11 Padres batters before walking Gonzalez and allowing Headley's single to center. Hairston forced Headley to end the inning.

The Padres had runners on second and third with two outs in the fifth before Gwynn struck out.
