The Nationals selected the contract of right-handed pitcher Taylor Hill from Triple-A Syracuse and designated infielder Greg Dobbs for assignment on Wednesday. Additionally, infielder-outfielder Jeff Kobernus was returned from injury rehab, reinstated from the disabled list and optioned to Syracuse, and right-hander Christian Garcia was released.

Hill, 25, was 9-2 with a 1.92 ERA in 15 games (14 starts) for Syracuse this season, tossing three complete games, one shutout and picking up one save. He posted a 7.22 strikeout-to-walk ratio (65 strikeouts and eight walks), the second-best mark of his career.

A sixth-round selection of the Nationals in the 2011 First-Year Player Draft, Hill is currently leading the International League in innings pitched (93 2/3), is tied for first in ERA and ranks second in WHIP (0.99).

Hill was named the International League Pitcher of the Week on May 26 after he tossed 11 shutout innings, pitching four innings in relief and earning a save against Columbus on May 19 and following it up with seven scoreless innings in a start against Pawtucket on May 24.

Dobbs, 35, was 6-for-28 (.214) with one double and two RBIs in 21 games for the Nationals.

Kobernus, 25, went 15-for-55 (.273) in 15 Minor League rehab games. He rejoins Syracuse's active roster for the first time since going on the disabled list with a fractured left hand on April 12.

Garcia, 28, posted a 2.13 ERA in 13 Major League games with the Nationals in 2012. He was 1-1 with a 2.45 ERA in 10 games with Triple-A Syracuse this season.
