The Dodgers promoted Steven Ames and Matt Magill to the 40-man roster Tuesday, as teams line up to protect players from the Rule 5 draft to be held in December.

Ames, 24, pitched for Double-A Chattanooga of the Southern League and was 3-3 with 18 saves and a 1.56 ERA in 54 games. The reliever struck out 72 batters in 63.1 innings of work and held right-handed hitters to a .177 average (25-for-141). Ames was selected by the Dodgers in the 17th round of the 2007 draft.

Magill, a product of Royal High School in Simi Valley, was drafted in the 31st round of the 2008 First-Year Player Draft. The 23-year-old started 26 games for Chattanooga in 2012, posting an 11-8 record with a 3.75 ERA. The right-hander fanned 168 batters in his 146.1 innings, including four games with 10 or more strikeouts.

The Dodgers currently have 38 players on their major-league roster. Teams have until 8:59 (PST) tonight to add any Rule 5 draft-eligible players to their roster — players who were 18 or younger when signed and have accrued five years of minor-league service time, and players who were 19 when they signed and have at least four years of service in the minors.
