Hill's swings in the batting cage were his first since being sidelined, thanks to a collision with Jays shortstop David Eckstein during a seventh-inning play against the A's on Thursday. Hill wasn't cleared to run through pregame fielding drills on Tuesday, but believed he'd be allowed to add more activities on Wednesday.
"You can't mess with those head injuries," Jays manager John Gibbons said. "The doctors sent him out there today to do the pregame stuff and then we'll see how he feels after that and we can go from there."
Hill indicated that the results of a CAT scan in California came back clean, but that he's still been dealing with some symptoms of a mild concussion. Hill said he's had mild headaches off and on, and that he's dealt with some dizziness and fatigue.
"Everything turned out fine," said Hill, referring to the CAT scan. "It wasn't to the extent where they needed to do any further testing. Now, it's just waiting for the symptoms to go away, the tired, the dizziness, the headaches.
"It's geting better, in my opinion. But they just want to take it very slow -- that's the frustrating part."
With Hill out of the lineup, Marco Scutato continued to fill in at second base and as the lineup's second hitter for the Blue Jays. Scutaro entered Tuesday riding a seven-game hitting streak in which he's hit .357 (10-for-28) with one home run, two doubles and four RBIs.
Also on Tuesday, Blue Jays catcher Gregg Zaun played catch for the first time since being placed on the 15-day disabled list with inflammation in his right elbow on Wednesday. Zaun, who is eligible to be activated on June 11, also took part in early batting practice.
"I felt pretty good," said Zaun, who plans on playing catch again on Wednesday and resting on Thursday. "It just felt like I hadn't thrown in a week. Hopefully, I'll be able to turn up the volume a little bit tomorrow and not feel anything."
In the meantime, the Blue Jays will continue to slot Rod Barajas into the order as their primary catcher. Barajas has taken full advantage of his increased playing time over the past month, hitting .389 (21-for-54) with four homers, five doubles and 14 RBIs in his past 17 games.
