Ronald Bolanos

Bolanos may have gotten lost in a sea of Padres' pitching prospects, though it was certainly hard to predict that he'd go on to make his major-league debut in 2019 after spending the entirety of the previous season at High-A Lake Elsinore, where he recorded an unconvincing 5.11 ERA. He improved that number to 2.85 in 10 starts at the same level to open the season and then recorded a 4.23 ERA in 76.2 innings for Double-A Amarillo, apparently a good enough number to earn him a big-league look in September. He looked generally overmatched in three starts and two relief appearances for the Padres, stumbling to a 5.95 ERA and a 13.6% walk rate. He's unlikely to be one of the Padres' top five starting options to begin the year and will probably open the season in Triple-A for the first time. He doesn't have a particularly impressive resume or prospect profile, so his next opportunity may come in relief.
