The Rangers designated two relief pitchers for assignment Tuesday night to clear roster space for the free-agent signings of starter Colby Lewis and reliever Kyuji Fujikawa.

Left-hander Scott Barnes and right-hander Ben Rowen were designated for assignment. The club has 10 days to trade, release or outright Barnes and Rowen to the minor leagues.

The Rangers now have a full 40-man roster with the additions of Lewis and Fujikawa.

Barnes was picked up from Baltimore on a waiver claim during the winter meetings and Rowen spent the bulk of the season with Triple-A Round Rock.
