Texas Rangers rookie right-hander Kumar Rocker makes his second MLB start and first at Globe Life Field on Thursday afternoon against the Toronto Blue Jays.

Despite eight baserunners on the walks, a hit batter, a pair of singles and a costly error by third baseman Ezequiel Duran, Rocker was charged with only one earned run. Had Duran fielded the two-out grounder in third, he might have allowed just one run, period.

Prospect made his Globe Life Field debut on Thursday. Could he join Cody Bradford, Jack Leiter in starting rotation?

Texas Rangers heralded young pitcher Kumar Rocker struck out five in his Globe Life Field debut but struggled with his command over three innings.

ARLINGTON — Here’s the deal: Statcast classifies Kumar Rocker’s nasty breaking pitch as a slider. He calls it a curveball and a “slider at times.” It was the most effective tool in his Texas Rangers debut last Thursday against the Seattle Mariners and secured five of his seven strikeouts.

The former Vanderbilt star may be the Rangers’ next ace after taking a circuitous path to the majors and making an electric MLB debut.
