The Oakland Athletics optioned their top two pitching prospects to the minors on Monday after reassigning a handful of players to their minor league camp on Sunday.
Right-hander Michael Ynoa, ranked as the A’s No. 2 prospect according to MLB.com, was optioned to Advanced-A Stockton, where he finished the 2014 season, and right-hander Raul Alcantara, the organization’s No. 6 prospect per MLB.com, was re-assigned to Double-A Midland. (h/t CSNBayArea.com)
First baseman Shane Peterson was also sent down on Monday.
Ynoa, 22, made two appearances for the A’s in Cactus League play and was 0-1, allowing three runs on five hits and three walks in three innings. He struck out three and surrendered a home run.
He was signed by the A’s out of the Dominican Republic in July 2008. The 6-foot-7 right-hander split last season between Class-A Beloit and Advanced-A Stockton, posting a 2.14 ERA and 1.152 WHIP in 54.2 innings with 48 strikeouts for the Snappers before having a tough adjustment at the higher level when he joined the Ports, notching a 7.71 ERA and 1.905 WHIP with 20 strikeouts in 21 innings.
Alcantara, 21, allowed an unearned run in four Cactus League innings, surrendering three hits and a walk and striking out two. He also traveled the Beloit-to-Stockton tour last summer, with a 2.44 ERA and 1.177 WHIP with 58 strikeouts in 77.1 innings for the Snappers and a 3.76 ERA, 1.139 WHIP and 66 Ks in 79 innings with the Ports.
Alcantara was originally signed by the Boston Red Sox out of the Dominican Republic in 2010 and came to Oakland in December 2011 along with Josh Reddick and Miles Head in exchange for Andrew Bailey and Ryan Sweeney.
Peterson, 25, had a cup of coffee with the A’s last April, going 1-for-7 with an RBI, but spent the majority of the season at Triple-A Sacramento, where he hit .251/.358/.387 in 126 games, with 70 runs, 25 doubles, 12 homers, 79 RBI and 17 stolen bases. He was a second-round draft pick of the Cardinals out of Long Beach State in 2008 and came to the A’s organization along with Clayton Mortensen and Brett Wallace in the July 2009 deal that sent Matt Holliday to St. Louis.
