Blue Jays selected the contract of 1B/3B Sean Keys from Triple-A Buffalo.

Keys is at first base and hitting sixth against the Rangers in his major-league debut with Vladimir Guerrero getting a break from the field at DH and George Springer taking a seat. The unheralded 23-year-old power-hitting prospect has put together a true breakout campaign after making some mechanical tweaks to his swing, slashing .284/.409/.619 with 21 homers and seven steals in 286 plate appearances in the upper levels of Toronto’s system. He’ll need to produce at the dish to keep his roster spot with the Blue Jays, but he’s an interesting bat-first prospect that fantasy managers should have on their radar screens, especially in deeper mixed leagues.
