The Oakland A's continue to hold down top spot in the TSN.ca MLB Power Rankings, upgrading their club with another ace pitcher before the non-waiver trade deadline.
The A's hold top spot ahead of the Los Angeles Angels of Anaheim and the Los Angeles Dodgers.
With five wins in six games, prior to Monday's loss, the Cleveland Indians made a move up the ladder, from 19 to 14.
The Detroit Tigers, who upgraded their rotation with the addition of ace starter David Price, moved up from eight to five, while the San Francisco Giants edged up from 14 to 11.
On the flip side of the Price trade, the Tampa Bay Rays sunk from 17 to 21.
The Milwaukee Brewers, missing ace Matt Garza, dropped from four to seven and the Atlanta Braves, who had lost six straight entering Monday's action, fell from seven to 13.
Despite not making any notable deadline acquisitions, the Toronto Blue Jays inched up, from 11 to 10, though their boost from the return of infielder Brett Lawrie may be shortlived, as he hurt his back in Monday's game.
