The Tampa Bay Rays claimed relief pitcher Wesley Wright off waivers from the Houston Astros, both teams announced on Monday.

The Astros will receive an undisclosed cash amount in exchange for Wright, who had been Houston's longest tenured player. The left-hander had spent six seasons with the team after being selected from the Los Angeles Dodgers in the December 2007 Rule 5 Draft.

Wright has limited lefty hitters to a .236 average over 286 career appearances in the majors, though southpaws are batting .305 against him this season. The 28-year-old has gone 0-4 with a 3.92 earned average in 54 outings thus far in 2013, topping all AL left-handers in games pitched.

"Wesley has been a great member of the community during his time in Houston," said Astros general manager Jeff Luhnow. "We appreciate everything he did for the organization and wish him the very best."

Wright is expected to join his new team when the Rays open a three-game series with Seattle at home on Tuesday.

Luhnow announced that the Astros will select the contract of pitcher Philip Humber from Triple-A Oklahoma City on Tuesday to fill the available roster spot.

Humber, who threw a perfect game against the Mariners while with the Chicago White Sox in April of 2012, began this season in Houston's rotation but was outrighted to the minors in May after going 0-8 with a 9.59 ERA over seven starts and two relief appearances.

The 30-year-old right-hander has pitched mostly in relief for Oklahoma City, compiling a 2-4 record with a 4.68 ERA over 20 games (seven starts).
