Rua suffered his ankle injury while fielding a ball in left field during yesterday's game against Houston. The first date he would be eligible to return is April 26. He started each of the Rangers' first 5 games this season in left field and has a .235 (4-17) average with a double, walk, and run scored.
Peguero, 28, was in Rangers spring training camp as a non-roster invitee, batting .340 (16-47) with a home run, 5 doubles, and 5 RBI in 21 Cactus League games. He was reassigned to minor league camp on April 1 and opened the season with Triple-A Round Rock, going 4-for-6 with a double, triple, walk, and 2 runs scored in the Express' first 2 contests at Oklahoma City on Thursday and Friday. Peguero has seen major league action in each of the last 4 seasons with Seattle (2011-12-13) and Kansas City (2014).
Edwards, 27, was optioned to Round Rock on April 4 at the end of spring training. He had no record and a 2.92 ERA (4 ER/12.1 IP) over 10 games/1 starts in Cactus League play this spring, holding opponents to a .167 (7-42) average with 5 walks and 18 strikeouts. He pitched in Round Rock's season opener on Thursday at Oklahoma City, earning a save with a scoreless 9th inning to finish a combined 2-0 shutout win (1.0 IP, 1 H, 0 R, 1 BB, 1 SO, 20 pitches/11 strikes). A converted outfielder, Edwards made his major league debut with the Rangers last season, posting no record with a 4.32 ERA (4 ER/8.1 IP) in 9 relief appearances.
With these moves, along with the transactions earlier today involving Stolmy Pimentel (received on waiver claim from Pittsburgh) and Lisalverto Bonilla (transferred from 15- to 60-day disabled list), the Rangers now have a full 40-man roster plus 7 players on the 60-day disabled list.
