That said, there’s some risk in Nunez’s profile as well. He’s a free-swinger who doesn’t strike out because he’d rather make contact with a pitch out of the zone than work the count, but he lacks any real power, so his offensive game is entirely about accumulating singles and then stealing second base. Baseball Savant has his expected wOBA, based on his exit velocity and launch angles, at just .269, ranking 219th of 241 batters with at least 200 at-bats. His speed will get him some extra hits that xwOBA won’t give him credit for, but he’s regressed as a hitter this year, even with his lower strikeout rate.
