<p>Once again, baseball reminds us we are so easily fooled. One night after witnessing a dramatic ninth-inning comeback victory by the <a class="Link" href="https://chicago.suntimes.com/cubs" target="_blank" >Cubs</a> that lures us into thinking this surely signals a change in the team’s fortunes, reality slaps us in the face.</p><p>This slap was a doozy: Giants 18, Cubs 3.</p><p>It rarely is that easy, even though <b>Jed Hoyer</b>, the Cubs’ president of baseball operations who was watching the comeback from the clubhouse weight room, admitted he, too, was thinking what we were.</p><p>‘‘I think everyone hopes that game is a catalyst,’’ he said, ‘‘and we’ll find out later on if it is.’’</p><p>We didn’t have to wait long, although it would be just like baseball for the Cubs to run off eight victories in their next 10 games after being pummeled by the Giants, who hit seven home runs en route to their 18 runs, marking the most homers and runs the Cubs have yielded this season.</p><p>The trade deadline Aug. 3 is now less than two months away.</p><p>‘‘The furthest thing from my mind right now,’’ Hoyer said, ‘‘given the way we’ve played.’’</p><p>That was before the game.
