Clay Buchholz (neck) was able to throw a bullpen session on Tuesday.
It's a good sign that he'll be able to avoid the disabled list and start on Saturday in Detroit. The Red Sox should provide an update on his status later Tuesday or Wednesday. If Buchholz can't go, Allen Webster or Rubby De La Rosa would likely get the ball.
Marco Scutaro is back in the Giants' lineup Tuesday.
Scutaro is dealing with "mallet finger" in his left pinkie, which is a form of tendon damage. The injury can often take 6-8 weeks to fully recover from, but Scutaro will try to play through it. He had missed the previous six games.
J.J. Putz (elbow) will begin a rehab assignment with Triple-A Reno on Thursday.
He'll remain with Reno through next Tuesday, as the D'Backs want him to appear in back-to-back games before being activated. Heath Bell has been scored upon in each of his last three outings and seems likely to cede the closer job back to Putz.
Michael Morse is not in the Mariners' lineup Tuesday due to his nagging right quad injury.
Morse originally suffered the injury in late May, and he's been unable to totally shake it. The M's have admitted that they would have placed him on the DL earlier had they not been dealing with other injuries, and they're probably wishing they would have gone ahead and done it, anyway. Morse was out testing the quad prior to Tuesday's game and is hoping to be back in the lineup soon.
Roy Oswalt is officially scheduled to make his Rockies debut Thursday in D.C. against the Nationals.
Oswalt signed a minor league contract with Colorado on May 2 and has registered a stellar 2.16 ERA, 0.93 WHIP and 25/7 K/BB ratio across 33 1/3 innings since reporting to Double-A Tulsa. The veteran right-hander is worth a try in most standard mixed fantasy leagues, though keep in mind that he struggled last year with the Rangers.
Mariners activated 1B Justin Smoak from the 15-day disabled list.
Smoak wound up missing a little under three weeks with a right oblique strain. He did not hit the ball well on his rehab assignment and will return to a .240/.350/.344 batting line. The 26-year-old first baseman remains a poor option in standard mixed fantasy leagues.
