Yaisel Sierra joins Class-A Rancho Cucamonga, to start Saturday night

LOS ANGELES -- New Cuban import Yaisel Sierra was added to the Class-A Rancho Cucamonga roster on Wednesday and will start for the Quakes this weekend, making his U.S. pro debut.

The right-hander, who turns 25 in June, signed a six-year, $30 million contract with the Dodgers in February, and joins Rancho Cucamonga from extended spring training, where he was working with coaches at Camelback Ranch.

The Dodgers plan to develop Sierra as a starter.

"A lot of guys you have that debate of starter or reliever, and it's nice to have a fallback," vice president of baseball operations Josh Byrnes said in February. "But we want to at least shoot for starter because there are enough ingredients in there that gives him a chance."

Sierra starts at home against High Desert on Saturday night, a 7:05 p.m. PT start in Rancho Cucamonga. He was originally slated for a Friday start, but Grant Holmes will start instead. Per Kyle Glaser of the Riverside Press-Enterprise:

Sierra's spot in the rotation is Friday, but @RCQuakes wanted Grant Holmes to pitch on regular rest on Friday instead #Dodgers

Sierra takes the roster spot of Trevor Oaks, who was promoted to Double-A Tulsa. Also joining the Quakes on Wednesday from extended spring training was Jeff Malm, the former first baseman and outfielder who converted to pitching last year. The left-handed Malm takes the place of pitcher A.J. Vanegas, who was placed on the seven-day disabled list.
