Minor matters

• Right-hander Carlos Martinez made his Triple-A debut on Tuesday, one day after the Cardinals unplugged him from the Major League bullpen in order to build him back up as a starter. Martinez threw 43 pitches (25 strikes) over three scoreless innings. He allowed two hits, walked one and struck out four. When Martinez was called up to the Majors in early May, he was pitching in the Double-A rotation.

• Out since May 12 with a right ankle injury, outfielder Oscar Taveras has been placed on the seven-day Triple-A disabled list. He will be eligible to come off as early as Saturday. Taveras was not initially expected to be sidelined this long from the injury. He continues to test his ankle through agility drills and running.

• Taveras' move to the DL opened up a roster spot in Memphis for outfielder Chris Swauger to be promoted from Double-A. In 47 games with Springfield, Swauger hit .279 with 12 extra-base hits.
