Yadiel Rivera

Rivera broke camp with the big league club in a utility role, but he hit a disappointing .196/.213/.261 over the first month-plus of the season before being sent back down to the minors. The 24-year-old spent the rest of the season bouncing back and forth between the majors and minors, though he posted a sub-.230 average and sub-.600 OPS at both levels. The infielder also struggled with his plate discipline, as he struck out 98 times combined at Triple-A Colorado Springs and the majors compared to just 12 walks. Rivera figures to enter spring training in a similar position this season where he'll fight for a backup infield job, but little in his career thus far suggests he'll be able to emerge as anything more than a reserve player even if he does crack the Opening Day roster.
