Roberto Hernández (starting pitcher)

Roberto Hernández, who for much of his career pitched under the name Fausto Carmona, possessed an arm that could silence major league lineups. Signed by the Cleveland Indians as a teenager, he initially struggled as a starter before a transformation in the bullpen unlocked his potential. With a heavy, sinking fastball that routinely touched the upper 90s, he became a nightmare for right-handed hitters. His most remarkable season came in 2007 under the Carmona identity, when he transitioned to the rotation and won 19 games, finishing fourth in Cy Young Award voting and helping lead Cleveland to the brink of the World Series. While his later years saw him return to a relief role, his power arm remained a valuable commodity. He pitched for seven different MLB clubs, a testament to his enduring ability to get outs. His journey, marked by a notable name change and a successful reinvention, is a classic baseball tale of adaptation and raw talent finding its niche.
