TORONTO – Outfielder Dalton Pompey, left-hander Matt Dermody and right-handers Ryan Tepera and Danny Barnes are expected to join the expanded Toronto Blue Jays roster Friday, according to multiple industry sources.

Barring an injury, Bo Schultz and Aaron Loup aren’t eligible to be recalled until after the triple-A season ends Sept. 5 because they haven’t been down in Buffalo on option for 10 days.

Pompey, 23, slashed .270/.349/.353 in 93 games with the Bisons this season, and stole 12 bases without being caught between June 3 and Aug. 16. While his all-around game has progressed steadily this year, his speed is a weapon the Blue Jays could deploy off the bench the way they did last fall.

Dermody’s promotion, first revealed by agency KVA Sports LLC on Twitter, is a bit of a surprise given that the 26-year-old opened the season at single-A Dunedin. But he posted a 1.82 ERA and a 1.16 WHIP over three levels with eight walks and 47 strikeouts in 54.1 total innings.

The Blue Jays have been searching for consistent left-handed support for Brett Cecil all year.

Tepera, 28, has been up and down multiple times this year, appearing in nine games with the Blue Jays, allowing three earned runs in 9.1 innings of work. At Buffalo, he has a 2.58 ERA and 18 saves in 20 chances over 45.1 innings.

Barnes, 26, made his big-league debut in August after dominating at double-A New Hampshire and Buffalo this year, posting a cumulative ERA of 0.73 and WHIP of 0.47 over 61.1 minor-league innings.
