Guzman trade official; Joaquin Arias on DL

ANAHEIM, Calif. -- The Rangers have made the Cristian Guzman trade official and have also placed Joaquin Arias on the disabled list with a strained back muscle to make room for Guzman on the roster.

Guzman will wear No. 12, as we noted last night, and will be in uniform and available tonight.

We updated you on all the particulars of that deal yesterday. But here's part of the team's release:

Guzman, 32, has batted .282 (90-319) with 2 homers, 11 doubles, 4 triples, and 25 RBI in 89 games with Washington this season. He has made 75 total starts, seeing action at second base (54), shortstop (16), right field (3), and designated hitter (2). His 54 starts at second base led the Nationals. He had played exclusively at shortstop in his big league career prior to this season, but has a .980 (6 E/293 TC) fielding percentage at second base this season.

A two-time All-Star (2001 and 2008), Guzman has a career .272 average with Minnesota (1999-04) and Washington (2005-10). He appeared in the postseason with the Twins for three straight years from 2002-04. Over the past 4 seasons since the start of 2007, the switch-hitter has compiled a .300 average, including a .336 mark against left-handed pitchers in that span. He batted a career-high .316 in 2008, 4th in the National League that year.

His 89 triples rank 4th among active players. He is a career .294 (32-109) hitter at Rangers Ballpark with 3 home runs and 14 RBI in 28 games.

Roark has gone 10-5 with a 4.20 ERA (49 ER/105.0 IP) in 22 games/17 starts with Double-A Frisco this season, just his 3rd professional campaign. He was originally selected in the 25th round of the 2008 June draft.

Tatusko has a 9-2 record and 2.97 ERA (33 ER/100.0 IP) in 24 games/13 starts for Frisco in 2010. He was the Rangers’ 18th round selection in the 2007 June draft.

Arias has batted .275 with no homers and 9 RBI in 46 games with Texas this season. He has started the past 2 games at second base. This is his second stint on the disabled list this season, as he was also down from April 30-May 15 with the same injury.

With these moves, along with the earlier trade with Boston, the Rangers still have a full 40-man roster.
