PHOENIX — Four years after he joined the Oakland Athletics, Michael Ynoa still has never pitched above Class A.
Signed by Oakland for $4.25 million when he was 16, Ynoa has been limited to 17 professional games because of elbow problems.
Now on the 40-man roster of the A's, the 21-year-old right-hander reported to spring training Thursday after missing the opening week because of chicken pox.
"For one week it was bad," Ynoa said.
Given his 6-foot-7 height, Ynoa caught the attention of A's manager Bob Melvin.
"I didn't realize he was that size," Melvin said. "He could probably reach out and drop the ball in the catcher's mitt. I'm looking forward to watching him pitch. Everybody says he's pretty special when he's healthy."
Ynoa has yet to go through a full season. He started his career on the disabled list with the A's affiliate in the Arizona Rookie League due to a strained right elbow, and he missed the entire season.
He made three starts in 2010 before more elbow problems, and had surgery that August to reconstruct his ulnar collateral ligament.
Ynoa returned to the mound last June and made a combined 12 starts and two relief appearances for the Arizona League A's and Vermont of the Class-A New York-Penn League, going 1-4 with a 6.45 ERA and 25 strikeouts in 30? innings. He is working on a cutter, a pitch that intrigued him when he saw it during televised games while he was sidelined.
"I feel great mentally and now I am ready to do my best and just keep going," Ynoa said. "I'm OK with everything."
