Pete Alonso’s disappointing performance in this year’s Home Run Derby wasn’t a particularly big deal for the future of his big-league career. His play over the next three months could be a different story. The 29-year-old is one of the most coveted free agents in Major League Baseball for the upcoming offseason and could make himself a lot of money — or potentially lose a lot of it — depending on how he plays in the second half of the season. Others who could use a good second half before hitting free agency including Cardinals first baseman Paul Goldschmidt and Astros third baseman Alex Bregman.
