Guzman gave up two hits and two walks over six scoreless innings while striking out a season-high 10 for Double-A Jacksonville on Thursday.
The 10 whiffs tied his career high. Guzman, acquired from the Yankees in the Giancarlo Stanton deal, is still trying to refine his command -- he's walked multiple batters in six straight starts and seven of eight on the season, leading to a 44:22 K:BB through 44 innings -- but he's still improved on last year's rough 6.0 BB/9 at High-A. His high-octane fastball will keep earning him chances as a starter, but if the 23-year-old doesn't start to put things together soon, a move to the bullpen could be in his future.
Guzman was optioned to Double-A Jacksonville, Andre Fernandez of The Athletic reports.
Guzman will likely spend all of 2019 refining his craft in the minors. He generates elite velocity with his fastball, but needs to greatly improve his command and secondary pitches.
Guzman was added to Miami's 40-man roster Tuesday, Clark Spencer of the Miami Herald reports.
Guzman was one of six prospects added to the 40-man roster for protection from the Rule 5 draft. The 22-year-old has a lively fastball and appears to have a bright future despite not advancing past High-A ball through his first four seasons in Miami's farm system.
Guzman (oblique) made his season debut at High-A Jupiter on Saturday, tossing four scoreless innings and striking out seven while working around three walks and two hits.
Per Joe Frisaro of MLB.com, Guzman's fastball sat in the 98-to-100 mile-per-hour range for most of the start, suggesting that he had no issues generating torque after battling the oblique injury for much of April. The 22-year-old Guzman, who was one of the key pieces acquired by Miami in the offseason trade that sent Giancarlo Stanton to the Yankees, is already viewed as one of the top pitching prospects in the organization even though he's likely at least a year away from reaching the big leagues.
Guzman is battling a minor oblique issue, Joe Frisaro of MLB.com reports.
Guzman's first start for High-A Jupiter is not yet scheduled, but he may be ready to go by the team's fifth game of the season on Monday. Guzman, part of the package sent from the Yankees in the Giancarlo Stanton trade, threw 66.2 innings for short-season Staten Island last season, posting a 2.30 ERA backed up by excellent peripherals, a 33.5 percent strikeout rate and a 6.8 percent walk rate. His electric fastball (which can touch 102 mph) makes him one of the top prospects in the Marlins' system, but he's still several years away from reaching the majors, having never played in full-season ball.
