The Dodgers added left-handed pitcher Onelki Garcia to their 40-man roster Wednesday and transferred Shawn Tolleson to the 60-day disabled list. Garcia is uniform for tonight’s game and will become the first player in franchise history to wear number 98 when he makes his major-league debut.

Garcia, 24, split 2013 between Double-A Chattanooga and Triple-A Albuquerque, where he allowed four runs in 9 ⅔ innings after being promoted Aug. 12. He posted a 2.75 earned-run average in 25 games (six starts) at Chattanooga.

Although Garcia is eligible for the Dodgers’ postseason roster, Dodgers manager Don Mattingly said that Garcia won’t pitch in October barring injuries.

“We need to make sure we have enough protection for Paco (Rodriguez) and J.P. (Howell),” Mattingly said.

A power reliever, Garcia throws a fastball and slider. He’s thrown 62 total innings this season, which is fewer than Jansen (70.2) and Belisario (62.1), and more than Howell (55.1) and Rodriguez (51).

A native Cuban, Garcia defected from the communist island in 2010 and reached Mexico on his first try. He was declared ineligible for the 2011 draft by Major League Baseball, and slipped to the Dodgers in the third round in 2012. Garcia was working out at Pierce College in Woodland Hills at the time I wrote this feature story about him last year. It’s worth a read.
