Baltimore beat up on CC Sabathia, Emilio Bonifacio became the first player in 41 years to hit an inside-the-park home run on opening day, and Jack Wilson gave Pittsburgh a comeback victory in the ninth inning.

Following a winter of worry about whether the recession would damage attendance, major league baseball returned across the nation Monday.

Atlanta beat World Series champion Philadelphia 4-1 on Sunday night and 26 more teams had been slated to open Monday before bad weather caused a pair of postponements: Tampa Bay at Boston and Kansas City at the Chicago White Sox.

They’ll now get going on Tuesday, when Milwaukee and the Giants were scheduled to meet in San Francisco in the last of the 15 openers.

On Monday it was Baltimore 10, the New York Yankees 5; and Texas 9, Cleveland 1 in the AL, with Detroit at Toronto, Seattle at Minnesota and Oakland at Los Angeles at night.

In the NL, it was the New York Mets 2, Cincinnati 1; Florida 12, Washington 6; and Pittsburgh 6, St. Louis 4.

Even with economic worries, most openers were sold out despite some chilly conditions.

At Camden Yards, Baltimore took advantage of a wobbly Yankees debut by Sabathia, whose $161 million, seven-year contract is the richest for a pitcher.

Sabathia allowed six runs, eight hits and five walks in 4 1-3 innings. He threw two wild pitches and failed to strike out any batters for the first time since July 2005.

At Arlington, Texas, the Rangers’ Kevin Millwood allowed one run over seven innings in his fourth consecutive opening-day start, and the Rangers scored seven runs in five innings off AL Cy Young Award winner Cliff Lee.

At Cincinnati, Francisco Rodriguez and the rebuilt Mets bullpen protected a slim lead for Johan Santana, who gave up three hits in 5 2-3 innings on a raw, 37-degree afternoon.
