<p>“Obviously, I’ve been terrible this year.’’</p><p>Clearly, Alex Bregman will get no dissenting votes from the folks who’ve taken to booing him with some regularity at Wrigley Field, as they did again Sunday night, when he popped out for the last out of the Cubs’ 2-1, 10-inning loss to the Giants.</p><p>In losing the rubber game of this three-game set, the <a class="Link" href="https://chicago.suntimes.com/cubs" >Cubs</a> have lost or tied their last nine series.</p><p>They’ve lost eight and split one with the Pirates and have gone a full month without winning a series.</p><p>That’s the formula to follow if you want to go from a 3œ-game lead in your division to the 7œ games they trail the Brewers by while sharing third place with the Pirates in the National League Central.</p><p>There were other losses for the Cubs on Sunday, too. Starting pitcher Jameson Taillon left one batter into the second inning with a strained left hamstring. He will have an MRI exam Monday; the Cubs can only hope the injury will not be as severe as the one that sidelined Shota Imanaga for seven weeks last season.</p><p>Energetic rookie Kevin Alcantara lost a bit of innocence when he was doubled off third on a broken-bat line drive by Bregman to Giants first baseman Rafael Devers in the eighth inning.
