Garcia -- rated the Dodgers' No. 15 prospect by MLB.com -- was the flavor of the day in postgame questions to Mattingly because he hasn't allowed a run in 8 1/3 innings over seven outings, with 10 strikeouts and two walks.
Mattingly reminded reporters that Garcia, a 24-year-old from the Dominican Republic, has enjoyed success at every level since being moved to the bullpen full-time in 2011. That includes eight appearances with the Dodgers last year, when he allowed two runs over 10 innings for a 1.80 ERA, with nine strikeouts and one walk.
"Obviously, he's pretty impressive," Mattingly said. "He's still here. As long as he's not in the [Minor League] barracks …"
The soft-spoken Garcia was asked if he feels he's ready to make the club.
"In my mind, yes," he said. "But I don't have control."
In addition to Garcia, relievers with the most impressive strikeout-to-walk numbers are Nicasio (10-0), Rodriguez (9-0), Chad Gaudin (9-0), Santos (9-0), Josh Ravin (9-0), Pedro Baez (7-0), Ryan Buchter (7-0), Adam Liberatore (6-1) and Aardsma (7-2). Ravin and Buchter have been sent to Minor League camp.
Gaudin will pitch two innings in a Minor League game Thursday, his first appearance since coming out of Saturday's game with a nerve twinge in his biceps.
