Nats' Rosenbaum Never Satisfied

WASHINGTON — Wherever lefthander Danny Rosenbaum starts this season, he plans to be even stronger than he was at the close of a successful 2011.
The 6-foot-1, 210-pound Rosenbaum lost 10 pounds through a daily routine that includes bench pressing and a more sugar-free, high-protein diet. He likely will return to Double-A Harrisburg, where he did not allow a home run in six starts over 39 innings after putting up the second-best ERA in the high Class A Carolina League.

If Rosenbaum is back with the Senators, he'll be reunited with pitching coach Paul Menhart, who helped the 2009 22nd-round pick improve his changeup en route to a 6-5, 2.59 stint in 132 innings at Potomac. The Xavier alum then went 3-1, 2.29 at Harrisburg. Overall, he had 135 strikeouts and 52 walks with four homers allowed.

Rosenbaum, one of the Nationals' top lefthanders, grew comfortable enough to use his changeup in any count, which he continued at Harrisburg. He also threw his curveball for more strikes and continued to show an effective slider and a 90 mph fastball that has cutting action.

"I just want to push myself to the absolute limit," he said. "I want to come back and have a better year than the year before. I don't want to be satisfied with what I've done. My goal is to get to the big leagues. I want to win a World Series with the Nationals, and this is how I have to do it."


• Former major leaguer Randy Tomlin, most recently the pitching coach at Harrisburg, will be unable to coach in the organization this season for family reasons. The longtime Lynchburg, Va., resident and Liberty alum will be a head coach at Lynchburg Christian Academy.

• The big league spring training schedule includes the Nationals' second meeting with Georgetown. When the teams played in 2008, lefthander Josh Smoker pitched two scoreless innings in a 15-0 win over the Hoyas. Smoker had a 2.31 ERA in 51 innings at Potomac last season.
