Oswalt has dominated the Padres in his career, going 4-0 with a 1.13 ERA in six career apperances, including four starts. The 26-year-old right-hander had a 5-1 victory at San Diego on July 7, giving up a run, six hits and striking out six over 7 1-3 innings.
That performance gave Oswalt victories in four straight starts, but the streak ended with Sunday’s 7-4 loss at Los Angeles. Oswalt, who was pitching on three days’ rest, gave up three runs and eight hits while striking out eight over six innings.
The Astros suffered a 5-1 loss in Garner’s debut as Astros manager on Friday.
“We’re disappointed,” the Astros’ Jeff Bagwell said. “But if anyone thought we were gonna win 74 games in a row, that’s not going to happen.”
Garner, who managed Milwaukee and Detroit to a combined 708-802 record during parts of 11 seasons, replaced Jimy Williams on Wednesday, the day after Houston hosted the All-Star game.
Carlos Beltran drove in the lone run for the Astros, who lost for the seventh time in nine games and fell below .500 for the first time since they were 1-2 on April 7.
Houston is a season-high 12 games behind NL Central-leading St. Louis.
“We just didn’t get anything rolling,” Garner said. “But I’m encouraged. I saw some good things out there tonight.”
The Padres have won two in a row after four straight losses.
Mark Loretta was 2-for-4 and drove in three runs for San Diego. He is 8-for-16 with a homer, two doubles and four RBIs over his last four games.
