MIAMI -- Lefty Jarlin Garcia, rated by MLB.com as the Marlins' No. 2 prospect, was among four pitchers added to the club's 40-man roster before Friday's 8 p.m. ET deadline.
Also joining the 40-man roster were right-handers Jacob Esch, Austin Brice and Nick Wittgren. The club also announced right-hander Matt Ramsey has been outrighted to Triple-A New Orleans.
The Marlins now have 38 players on their 40-man roster.
If Miami didn't protect those four pitchers, they would have been eligible to be selected in the Rule 5 Draft in December.
International and high school players signed at age 18 must be added to the 40-man roster within five seasons or they become eligible for the Rule 5 Draft. Players signed at 19 or older must be added within four seasons.
Garcia, who represented the Marlins in the Futures Game, split time at Class A Advanced Jupiter and Double-A Jacksonville, combining for a 3.57 ERA. The 22-year-old threw 133 2/3 innings, striking out 104.
Wittgren, Miami's No. 11 prospect, had 64 strikeouts in 62 2/3 innings at New Orleans.
Brice, the club's 16th-best prospect, had a 4.67 ERA and struck out 127 in 125 1/3 innings at Jacksonville.
Esch, 25, was Miami's 11th-round pick in 2011, and he pitched eight innings for the Rookie League Marlins, 85 1/3 innings for Jacksonville and 30 innings at New Orleans, posting a combined a 3.72 ERA in '15.
