The Kentucky Wild Health Genomes of the independent Atlantic League recently signed outfielder Moisés Sierra and left-hander Brandon Leibrandt, according to the league transactions log. Both players have some big league experience, with the former having appeared in parts of four MLB seasons.
The bulk of Sierra’s big league work came in the first half of the last decade. A fairly well-regarded prospect during his days in the Blue Jays farm system, he debuted with Toronto in 2012 and would spend parts of the next three seasons north of the border. Sierra had some success during a 35-game stint in 2013, when he hit .290/.369/.458. He didn’t produce much at the plate in any other season, however, and he hit .243/.296/.383 in 449 plate appearances overall from 2012-14.
Sierra returned to the big leagues for 27-game run with the Nationals in 2018, but he’s otherwise bounced between various Triple-A affiliates and foreign pro leagues. The righty-hitting outfielder owns a .277/.342/.421 line in parts of six Triple-A seasons. He spent some time in 2020 with the Chunichi Dragons of Japan’s Nippon Professional Baseball and played with the Mexican League’s Tecolotes de los Dos Laredos last year. He hit .300/.385/.462 over 226 plate appearances there and will now try to work his way back into the affiliated ranks with the Genomes.
Leibrandt doesn’t have the same level of experience in the majors, but his MLB time was more recent than that of Sierra. The Florida State product made five outings and tallied nine innings of relief for the 2020 Marlins. Leibrandt spent last season in the upper ranks of the Miami system, combining for a 5.68 ERA over 88 2/3 innings between Double-A Pensacola and Triple-A Jacksonville. The 29-year-old has had more success in past stints at the minors’ top level, where he owns a 3.61 ERA in parts of three seasons.
