Martinez hits first two HRs for Cards

ST. LOUIS -- Tino Martinez hit his first two homers of the season, and Travis Smith pitched six impressive innings for his first career victory as the injury-depleted St. Louis Cardinals beat the Florida Marlins 6-4 Wednesday night.

The Cardinals, who won for only the fifth time in 15 games, have five starting pitchers on the disabled list. Smith, making his second career start, allowed only Mike Lowell's second-inning home run.

Smith (1-0) was a stand-in starter for Garrett Stephenson, who was scratched earlier in the day and remained on the disabled list because the team wasn't confident he's fully healed from a lower back injury.

The 29-year-old Smith gave up three hits, walked two and struck out four. He signed as a minor league free agent in November after leading the Texas League with a 15-8 record for Double-A Round Rock last season.

Jason Isringhausen got the last four outs for his fourth save in five chances, overcoming two errors by second baseman Fernando Vina in the ninth.
