ATLANTA -- Blue Jays left fielder Travis Snider is scheduled to meet with a neurologist Tuesday in Las Vegas after being hit on the brim of his helmet during a Triple-A game Friday.

"The initial concussion has been confirmed," manager John Farrell said. "He is not traveling with the team to Reno and until [Tuesday], we'll have no more definitive news on the current status and any kind of projected return to play."

Once the concussion has been treated, Snider will have to undergo a bevy of tests before he'll be cleared to resume playing.

"As we've seen with Yunel [Escobar] here and other guys that have suffered that, there's going to be a battery of tests and re-administering those tests to ensure that those symptoms have dissipated before he gets back on the field," Farrell said.

Farrell said Snider will have to go through the impact test and baseline testing, like every player that comes into Spring Training, and will then go through exertion tests.

"And rightfully so, to protect the player and his health," he said. "There are steps that we have to fulfill here."

Snider, who began the season with Toronto before being sent down to work on his mechanics, played four innings after taking the hit before he was taken out due to dizziness. At the time, Snider showed no effects of a concussion.

"We have complete trust in the experience of the medical people that are on staff and their capabilities in the moment," Farrell said. "If there is any concern, if there is any doubt, then we're always going to side on caution and remove the player at that point in time.

"But if there are no clear or relevant symptoms based on the impact, then that's what we have to go by."

Drabek's control off in first Triple-A start

ATLANTA -- Blue Jays pitcher Kyle Drabek, sent down to Triple-A to work on his command, struggled in his debut for Las Vegas on Sunday, allowing a season-high seven walks and five runs in four innings.

"The line was not good, and even by his own admission. A lot of walks, a lot of pitches," Toronto manager John Farrell said. "His composure on the mound was better than what we saw in recent starts here. His composure and dealing with that frustration was a little bit better."

Farrell said they will attempt to cut down on Drabek's use of the cutter. Twenty-seven of his 106 pitches Sunday were cutters and Farrell wants to see more use of his four-seam and two-seam fastball.

"A lot of times, while the cutter is a very effective pitch, it can be somewhat a short cut to end results," Farrell said. "And not to say that we're trying to equip him less, but what's clearly needed is improved fastball command, whether that's in Las Vegas or Toronto. That's now the focus of emphasis in his development and an area that's got to continually be improved upon."

Farrell said Drabek's use of the cutter became somewhat of a security blanket for the righty, who is 4-5 with a 5.70 ERA in 14 starts for the Blue Jays this season.

"When you combine his curveball and changeup, in addition to the cutter, you're down to about a 50 percent usage of his fastball," Farrell said. "And when you grade them all out, his fastball has still got the best potential of any one of his pitches. And we have to maximize his potential."

Club sees effects of rotation's strong turn

ATLANTA -- Blue Jays manager John Farrell said Monday his rotation's ability to pitch inside more effectively has been the key to its recent success.

On the rotation's last turn, Jays starters compiled a 3-1 record and limited opponents to just seven earned runs in 35 innings. They struck out 30 and walked just six

"After a tough series against Boston, I thought the starters have really set the tone with not only throwing strike one and working ahead in the count, but we've pitched in more effectively," Farrell said.

The Blue Jays' pitching staff gave up 35 runs in that three-game series with the Red Sox. But since Ricky Romero limited the Orioles to just a run over eight innings of work last Wednesday, the Jays' five starters have all registered quality starts and pitched at least 6 2/3 innings.

"It came apparent that if you pitch out over the plate against a powerful hitting lineup, you're not going to create any uneasiness in the opposition standing in the batter's box," Farrell said. "It's not that we've hit anybody. We haven't purposely knocked people down. But we've been much more assertive in off the plate."

And now, Farrell and the Blue Jays are beginning to see the benefits of the rotation's recent performance.

"The most benefit is the game is typically under control. When our starters have worked deeper in the [game] it's given our bullpen a chance to fall in line more readily," Farrell said. "Where you've got guys that come to the mound assuming that the starter has gotten to the seventh inning, will typically come to the mound having appropriate amount of rest. It allows you to match up a little bit more regularly."
