The NL rookie of the year at 21 in 2013, Fernandez was the Marlins' opening-day starter last year, but his ascent was interrupted by an elbow ligament injury that required reconstructive surgery. He won't be the only pitcher making a comeback Thursday — his opponent, Giants right-hander Matt Cain, will start for the first time since July 2014.
Cain underwent elbow surgery last year and has been sidelined this season with a strained flexor tendon. Another starter on the disabled list, Jake Peavy, is scheduled to rejoin the San Francisco rotation Friday.
Orioles designate Young
Outfielder Delmon Young was designated for assignment by the Baltimore Orioles, who needed the roster spot to fortify their thin bullpen.
Young signed a one-year, $2.25-million deal during the off-season after batting .302 with seven homers and 30 runs batted in in 83 games in 2014. He also delivered a clutch three-run double to give the Orioles a win over Detroit in the postseason. He was batting .270 with two homers and 16 RBIs this season.
The Orioles recalled right-handed reliever Tyler Wilson from triple-A Norfolk.
