BALTIMORE -- Craig Stammen is the likeliest candidate to be recalled from Class AAA Syracuse to start Tuesday night in Atlanta.
Stammen, who was optioned to Syracuse earlier this month to make room for Stephen Strasburg's arrival, has righted his ship in the minors. In three starts with the Chiefs, he is 2-0 with a 2.25 ERA, having allowed only one run over his last 13 2/3 innings.
The right-hander also lines up well to slide into the spot in the Nationals' rotation made available when John Lannan was demoted to Class AA Harrisburg last week. Stammen could start Tuesday on five days' rest, making him a more likely choice than left-hander Matt Chico (who is 4-5 with a 3.36 ERA in the minors this season but just pitched on Friday and would have to come back on short rest to start Tuesday against the Braves).
Manager Jim Riggleman said prior to today's series finale against the Orioles that the Nats have settled on Tuesday's starter. They won't announce the move until tomorrow, though, because they first have to select a player (most likely a reliever) to remove from the roster.
Ross Detwiler, who is expected to join the big-league rotation at some point this summer, still isn't ready according to organizational sources. The left-hander, who missed the season's first two months following hip surgery, has allowed just one run in 10 2/3 innings at Harrisburg and Class A Potomac. But he was scratched from his last start due to a minor back injury, has yet to throw more than four innings at a time and is not yet throwing at full velocity.
