<p>Cubs manager <b>Craig Counsell</b> said speedy outfielder<b> Justin Dean</b> would be used in pinch-running and defensive-replacement roles after his call-up from Triple-A Iowa before Friday’s 16-2 victory against the Blue Jays.</p><p>The 29-year-old Dean replaced hot-hitting <b>Pete Crow-Armstrong</b> in center in the seventh inning after the Cubs had taken an 11-2 lead. In the bottom of the frame, Dean tripled with the bases loaded for his first major-league hit.</p><p>Dean, from Maudlin, South Carolina, had toiled in the minors and Mexico for 10 seasons before appearing in 18 regular-season games with the Dodgers last season. But he had only two at-bats and plate appearances as he was relegated to a specialized role in Los Angeles.</p><p>Dean went on to appear in 13 postseason games with the World Series champs but had no plate appearances, even if he did score as a pinch runner.</p><p>In his first at-bat with the Cubs, the right-handed batting Dean sliced a center-cut sinker from right-handed submariner <b>Tyler Rogers</b> beyond right fielder <b>Jesus Sanchez</b> and into the corner.
