RHP Dominic Leone selected from Triple-A Tacoma

RHP Hector Noesi designated for assignment.

OAKLAND, Calif. -- Seattle Mariners Executive Vice President & General Manager of Baseball Operations Jack Zduriencik announced today that right-handed pitcher Dominic Leone has been selected from AAA Tacoma.

Leone (lee-OWN) will be in uniform (#52) for tonight's game vs. the Oakland A's (7:05 pm) at O.co Coliseum.

To make room on the 40-man roster, RHP Hector Noesi has been designated for assignment. The Mariners have 10 days to trade, release or outright Noesi's contract to the minors.

Leone, 22, is in his third season in the Mariners organization after being selected in the 16th round of the 2012 June Draft out of Clemson University. In two minor league seasons, Leone has combined to go 4-3 with 21 saves and a 1.95 ERA (21 ER, 97.0 IP) in 67 appearances. In 48 appearances last season with A Clinton, A High Desert and AA Jackson, Leone combined for 16 saves, 64 strikeouts and a 2.25 ERA. Following the season he led the Arizona Fall League with 6 saves (0-1, 3.00 ERA, 11 G, 15 K, 1 BB).

As a non-roster invitee in spring training Leone posted a 1.80 ERA (2 ER, 10.0 IP) with 10 strikeouts and a .171 opponent batting average (6x35) in 9 appearances. He was reassigned to minor league camp on March 28 and was set to begin the season with the Rainiers, who had their season opener rained out last night.

Leone was college teammates with Mariners shortstop Brad Miller at Clemson (2010-2011).
