After Howson's rapid reply, the Leeds fans grew increasingly frustrated until Becchio put them ahead again with a close-range finish following a Leigh Bromby knock-down.
Shortly afterwards, the Yorkshire side appeared to take a decisive grip on the contest when Becchio headed his 17th goal of the Championship season after Bromby's initial effort cannoned off the post.
Young defender Leigh Bromby was a bit too keen to impress in the ninth minute, giving away a free-kick 20 yards out and earning himself a yellow card with a clattering challenge on Jay Bothroyd.
