The Red Sox are making a push to obtain Toronto ace Roy Halladay before the start of baseball?s winter meetings Dec. 7. But the Blue Jays reportedly want top prospect Casey Kelly along with young starter Clay Buchholz. The Sox could retreat from the deal if the Blue Jays continue to demand Kelly. The 20-year-old was their first pick in the 2006 draft and signed for $3 million. Kelly has been both a starting pitcher and a shortstop in the minors after turning down a scholarship to play quarterback at the University of Tennessee. Kelly went 7-5 with a 2.08 ERA on the mound, striking out 74 over 95 innings with only 16 walks. He is less advanced at the plate, having hit .219 with 4 home runs and 91 strikeouts over 292 at-bats. He finished last season in Single A ball.
