<p>The Cubs would like to believe they’re getting back to being their old, offensive selves.</p><p>They hit the Blue Jays and veteran starter Kevin Gausman with seven runs in the first inning on Friday at Wrigley Field and just kept pouring it on in a 16-2 win.</p><p>Carson Kelly provided the big blow in the early outburst — his second career grand slam — off Gausman’s first pitch to him, a down-the-middle slider.</p><p>Seiya Suzuki’s double to the right-field corner had already given the North Siders a 2-0 lead. Then Kelly’s drive sailed 428-feet, landed just under the left-field video board and made it 6-0.</p><p>Add three more singles and the Cubs tied their season-high with seven runs in a frame.</p><p>The rally was enough for the Cubs to win a second consecutive game and for the sixth time in eight. Starter Ben Brown went on cruise control, throwing 51 of 72 pitches for strikes through six innings, walking none.
