Demoted to work on his control, RHP Kyle Drabek struggled Sunday in his first start for triple-A Las Vegas. Drabek walked a career-high seven in four innings as he allowed five runs — four earned — on eight hits, while striking out three.

Drabek threw 106 pitches, only 55 for strikes.

Blue Jays manager John Farrell wants Drabek to work on controlling his fastball and cut down on the amount of cutters.

Drabek issued 68 walks in 162 innings in 27 starts with double-A New Hampshire in 2010, and he walked 50 in 158 innings in 2009.

"(Red Sox manager) Terry Francona did the same thing with Jon Lester earlier this month," an American League advance scout said.

"It's so hard to find a kid with a power arm who can throw a good four-seam fastball. You throw a cutter, you lose the mindset of throwing the ball by the hitter. You're pitching to get ground balls.
