Cardinals prospect OF Oscar Taveras extended his hitting streak to 11 games Sunday, going 2-for-4 with a home run at Triple-A Memphis. The home run was Taveras' fourth of the season, and he's now batting .313/.360/.513 with eight extra-base hits and 13 RBI in 21 games. During his current 11-game hitting streak, the 21-year-old outfielder is batting .342 with two home runs. The Cardinals just called up Randal Grichuk from Triple-A, but Taveras has seen increased playing time in center field lately, which suggests the organization is exploring ways to get his bat in the lineup sooner rather than later this season.
