\ McGeary, a hard-throwing 18-year-old from West Roxbury, Mass., had hoped all along to get first-round money and had threatened to enroll in classes at Stanford if his demands weren’t met. The Nationals, though, felt all along they had a shot to sign him, and once ownership was convinced yesterday to pay above “slot” for McGeary, the deal was finalized.\
\ McGeary, who went 6-1 with an 0.88 ERA in seven starts as a senior for Roxbury Latin High School, becomes the last of Washington’s top 20 draft picks to sign. He joins fellow left-handers Detwiler (the sixth-overall pick who received $2.15 million) and Josh Smoker (the 31st-overall pick who got $1 million) in agreeing to terms.\
\ “We are very pleased to be able to draft and sign three left-handed starting pitchers … all blessed with first-round talent,” general manager Jim Bowden said.
