Rzepczynski went 2/3 with a 4.43 ERA in 45 games this season. Earlier this week, the Indians, who recently lost six straight games and fell back in the AL wild-card race, dealt outfielder David Murphy to the Angels and sent slugger Brandon Moss to St. Louis.
The 26-year-old Almonte has split the season between San Diego and Triple-A El Paso, batting .275 with four homers, 35 RBIs and 11 steals in 61 games in the minors. He has spent two stints in the majors, batting .204 in 31 games. The 5-foot-9, switch-hitting center fielder signed with the Yankees in 2005.
Rzepczynski joined the Indians in 2013, coming over in a trade with St. Louis. He appeared in 73 games last season.
