Watch LIVE as No. 5 prospect Kayfus plays at Triple-A

Sunday, 7:05 p.m. ET — El Paso Chihuahuas (SD) @ Round Rock Express (TEX)
There’s no doubt that Kumar Rocker (TEX No. 2/MLB No. 36) has electric stuff — the right-hander shows three plus-or-better pitches, including a 70-grade slider. The Rangers sent the former Vanderbilt ace back to Triple-A as he works to harness his sky-high potential, and he’ll face El Paso for the second time this week. The Padres’ talent is led by outfielder Tirso Ornelas (SD No. 11), who has displayed impressive exit velocities and on-base skills.
