SAN DIEGO (AP) -- Tyler Lyons pitched seven solid innings in his major league debut on the same day St. Louis lost Jaime Garcia for the season, and the Cardinals beat the San Diego Padres 5-3 on Wednesday night.

Lyons, who was promoted from Triple-A Memphis after Garcia went on the disabled list, allowed one run and four hits. The 25-year-old left-hander was a ninth-round draft pick in 2010 out of Oklahoma State.

The Cardinals announced before that game that Garcia will have season-ending shoulder surgery this week. The lefty went 5-2 with a 3.58 ERA in nine starts this year, helping St. Louis bolt to the majors' best record at 30-16.

Yadier Molina had four hits and Carlos Beltran finished with three as the Cardinals took two of three from the Padres.

San Diego rookie Burch Smith failed to record an out in the second inning for the second time in three major league starts. The right-hander struggled with his command, walking three before he was lifted with no outs in the second.

Tim Stauffer came in and got Matt Holliday to hit into a double play, but Matt Carpenter scored to give the Cardinals a 4-0 lead. Smith allowed five hits and has given up 15 runs and 16 hits in just 7 1-3 innings.
