(AP) — Jose Martinez hit two home runs, rookie Harrison Bader added a career-high three RBIs and Michael Wacha survived a shaky start to last six innings as the St. Louis Cardinals beat the San Diego Padres 8-4 on Tuesday night.

Martinez added a double to go 3 for 3 and finish with three RBIs.

Bader, who was a September call-up on Friday, smacked his third home run and had his third multi-hit game since being summoned.

Wacha (11-7), who blanked the Padres over his last four innings, was charged with four runs (three earned) and seven hits. He walked three and struck out six in winning for the second straight time after suffering three consecutive losses.

Three Cardinals relievers shut out the Padres in the final three innings.

Travis Wood (2-2) lasted two-plus innings and was nicked for two home runs. Wood was rocked for seven runs (six earned) and seven hits, with two walks and two strikeouts. It was his second loss in his last three decisions.

Neither starting pitcher was effective early, although Wacha didn’t struggle as badly as Wood.

Both teams came out swinging as they combined for 11 runs through the first 2 1/2 innings.

The Cardinals scored twice in the first when Martinez smacked his 12th homer, a two-run shot off Wood’s 85 mph cut fastball.

The Padres tied it with two of their own, on Wil Myers’ RBI single and Bader’s throwing error.

St. Louis tacked on three runs in the second, in what would be Wood’s last full inning. Bader compensated for his erratic throw with a three-run homer into the left-field seats for a 5-2 lead.

San Diego made it 5-4 thanks to an unlikely, but not surprising, power source: Wood. He blasted a two-run homer, his 12th career homer (counting the playoffs) and his second one in consecutive outings.

But Wood didn’t record an out in the third, pulled after 45 pitches. Stephen Piscotty and Yadier Molina each contributed RBIs for a 7-4 lead.

Padres rookie Miguel Diaz threw four innings of scoreless relief.
