Batting practice is supposed about 90 minutes before the start of the game for visiting teams. Apparently, nobody told David Ortiz.

Picking up right where he left off the night before, Ortiz belted a double and two more homers, knocking in two runs to help the Red Sox bash the Minnesota Twins, 9-4.

With a win Thursday, the Red Sox can win their fourth straight series.

Ortiz hit two homers and had two RBI-singles in the series opener Tuesday. In two games, he has seven hits, four homers and six RBI. The last Red Sox player to have back-to-back two-homer games? Also Ortiz, on July 4-5, 2003.

Grady Sizemore and A.J. Pierzynski -- the latter, a former Twin like Ortiz -- also knocked in two runs each in support of Felix Doubront, who turned in his best outing in almost a month, holding the Twins to a single run over 6 1/3 innings.

But the star was Ortiz, who doubled in the first to help set up the first run, smacked a two-out solo homer in the third and led off the fifth with another. In 13 career games at Target Field, Ortiz has nine homers.

For the road trip, Ortiz is 12-for-21 with five homers.

With his second homer of the night, Ortiz moved into 39th place all-time, tying Dave Kingman with 442 career home runs.

Burke Badenhop pitched the eight and allowed an unearned run. Edward Mujica allowed a two-run homer to Trevor Plouffe in the ninth before getting the final out.
