Lefty Jarrod Washburn, left fielder Raul Ibanez and third baseman Adrian Beltre all had their names in play as the trading deadline approached, but the deal to move the 38-year-old Rhodes was the only time the Mariners pulled the trigger.
For the moment, the Mariners are left with just one lefty in the bullpen, rookie Cesar Jimenez. Unlike Rhodes, who tended to dominate left-handed hitters, Jimenez has had most of his success against right-handers.
The Mariners will make a move to fill Rhodes' spot on the roster Friday, and one of the candidates is lefty Ryan Rowland-Smith, who had been in the bullpen all year before starting a mid-July conversion to the rotation at Class AAA Tacoma.
Hernandez is scheduled to report to Class AA West Tennessee and should make his first start for the Diamond Jaxx on Sunday.
General manager Lee Pelekoudas said the club came close on a couple of other deals and said the Mariners would remain open to working a waiver wire deal if the opportunity arises.
MARINERS 8, RANGERS 5: RHP R.A. Dickey, who spent the first five years of his big-league career with the Rangers, threw shutout ball for seven innings before fading in his first-ever appearance against Texas.
Dickey, propped up by four runs in the first two innings, had a two-hit shutout into the eighth before 3B Ramon Vazquez pounded a two-run homer.
RF Ichiro Suzuki tripled, doubled, scored two runs and drove one in with a sacrifice fly as the Mariners collected 11 hits, their sixth consecutive game with double-digit hits.
--2B Jose Lopez went hitless in his first four at-bats but singled to left in his fifth try Thursday, extending his hitting streak to 18 games. It's the longest streak of his career, and it's tied for the longest active streak in the big leagues. Dodgers OF Matt Kemp also has hit safely in 18 consecutive games.
--RHP Gaby Hernandez was acquired from Florida for LHP Arthur Rhodes in the final hours before the trade deadline. Hernandez will move into the starting rotation at Class AA West Tennessee for the moment.
--3B Adrian Beltre, who was supposed to get Thursday off, settled for DH duty and hit his 19th homer while driving in three of the Mariners' eight runs.
--RHP R.A. Dickey, making his first career appearance against the team he broke into the big leagues with, threw seven shutout innings against Texas on Thursday. He had a two-hitter going until the eighth, when 3B Ramon Vazquez homered with a man aboard.
--SS Yuniesky Betancourt was in the original starting lineup, then was scratched because of a sore elbow. He could miss a game or two more before he is ready to play.
--C Jeff Clement was supposed to return to the starting lineup Friday after missing a week because of a split right thumbnail. But because the Mariners are facing a lefty, Baltimore's Garrett Olson, the left-handed Clement may have his return to the lineup delayed until Saturday.
BY THE NUMBERS: 7 -- Games in the Mariners' losing streak that ended July 27, matching the club's longest slide of the season.
QUOTE TO NOTE: "It felt (good) to get one hit, then get two. After that, I was looking for my third." -- C Kenji Johjima after getting two hits July 25. He'd had just two hits in 38 July at-bats before that.
SS Yuniesky Betancourt (sore elbow) did not play July 31 and could miss a game or two more. DH Jose Vidro (back and neck spasms) was held out of the July 29 game. He appeared as a pinch hitter July 30, but he didn't play July 31.
RHP Carlos Silva (lower back tightness) left the July 20 game. His scheduled July 26 start was pushed back, and he was hit hard July 29.
C Jeff Clement (cracked right thumbnail) left the July 22 game. He didn't play July 23-27, then was the DH on July 28 and didn't play July 29. He will be ready to return to the lineup as of Aug. 1.
LHP Erik Bedard (sore left shoulder) went on the 15-day disabled list retroactive to July 5. He was unable to throw July 21, but an MRI the next day showed the same impingement he has had.
RF Mike Morse (dislocated left shoulder) went on the 15-day disabled list April 14. He had surgery April 22 and probably won't play again this season.
