TORONTO - Manager John Farrell is preaching a new offensive philosophy in his first campaign with the Toronto Blue Jays.

He wants the homer-happy club to use its speed more often on the basepaths. It didn't take long for his players to show him they're listening.

Rajai Davis legged out an infield single in Toronto's opening at-bat to kickstart a four-run first inning en route to a 13-3 rout of the Minnesota Twins on Friday. The Blue Jays also showed they still have some pop at the plate, blasting four home runs to thrill a raucous sellout crowd at Rogers Centre in the regular-season opener for both teams.

Before the game, Hall of Fame banners were unveiled for former Toronto second baseman Roberto Alomar and former team executive Pat Gillick. The ceremony gave the towel-waving crowd of 47,984 plenty of energy, creating an electricity in the stadium rarely seen since the team's glory days in the early 1990's.

In the opening frame, the speedy Davis was nearly picked off first but instead survived a rundown by sliding back to the bag on a high throw. After a Yunel Escobar single, the duo teamed up for a double steal and both later scored. It's the kind of aggressive baserunning that Farrell wants to see from the younger, faster squad that general manager Alex Anthopoulos has assembled for the 2011 campaign.

Ricky Romero (1-0) was solid in his first game as the team's No. 1 starter, giving up one earned run over six-plus innings. Casey Janssen, Jason Frasor and Carlos Villanueva finished up in relief.

Minnesota starter Carl Pavano (0-1) was lit up early and often, as the Jays tagged him for seven earned runs in four-plus innings. He gave up a two-run homer to rookie catcher J.P. Arencibia in the fourth inning and a pair of no-doubt solo blasts from Jose Bautista and Adam Lind in the fifth. Arencibia capped the four-run frame with a run-scoring triple and added a solo shot in the eighth.

Romero, meanwhile, kept the Twins at bay until the seventh inning, when he was chased after giving up an RBI double to Alexi Casilla. The young southpaw got a standing ovation from the crowd for his seven-hit, seven-strikeout performance, and he waved his hat in appreciation on the walk to the dugout.

Arencibia and Bautista paced Toronto's 12-hit attack with three hits apiece. Canadian slugger Justin Morneau played his first regular-season game since suffering a concussion during a game against the Jays on July 7. The New Westminster, B.C., native went 0-for-4 and left three runners on base.

Toronto improved its all-time record to 18-17 on opening day while Minnesota fell to 24-27.
