<p>DETROIT — What makes the <a class="Link" href="https://chicago.suntimes.com/white-sox" target="_blank" >White Sox</a>’ playoff push unusual is that they’re doing it with players lacking major-league experience. And some of them aren’t just lacking that, they’re lacking it at the position they’re playing.</p><p>Case in point: Jacob Gonzalez.</p><p>The Sox called up Gonzalez with the intention of playing him at first base after Munetaka Murakami suffered a strained right hamstring May 29, even though Gonzalez, primarily a shortstop, had started only five games there in his college and minor-league careers. He forced his way onto the roster with 19 home runs in 52 games at Triple-A Charlotte this season.</p><p>‘‘He’s here to play first base for us,’’ manager Will Venable said days after Gonzalez’s call-up.
