8:16pm: Oswalt is not close to signing, reports Morosi (on Twitter). The Red Sox remain very much involved, he says.
6:53pm: With the Marco Scutaro trade providing $6MM of salary relief, the Red Sox have now intensified their pursuit of Roy Oswalt according to Jon Paul Morosi of FOX Sports (all Twitter links). They are not the only team in on the right-hander, though the Tigers are only on the fringe of the sweepstakes. Morosi calls the situation "fluid."
Oswalt, 34, is reportedly looking for a one-year deal worth $8MM. Earlier this week we heard that Boston would have to move some money to be able to afford him, which is exactly what the Scutaro trade did. Oswalt pitched to a 3.69 ERA with 6.0 K/9 and 2.1 BB/9 in 139 IP for the Phillies last season, missing time with back problems. Prior to that, the long-time Astro made at least 30 starts and threw at least 180 IP in seven straight seasons.
