The right-hander has been stellar over his last three outings for the Arizona Diamondbacks heading into Thursday's matchup in Arlington.
Texas (32-20) was swept Monday in a doubleheader at Arizona after falling 4-3 in 13 innings at Seattle on Sunday.
"(Sunday) we had a chance to win the game and today we had a chance to win both of those games,'' catcher A.J. Pierzynski said after 5-3 and 5-4 defeats in Phoenix. "It just wasn't meant to be."
Wednesday's contest wasn't meant to be, either, and was postponed due to unplayable field conditions caused by a severe thunderstorm about an hour before the game was scheduled to start.
The contest will be made up at a later date, likely Aug. 15, a mutual off day for both teams.
The Rangers will still see a familiar face on the mound in McCarthy (2-3, 4.36 ERA), who pitched for them from 2007-09 before spending the last two seasons with Oakland. McCarthy has gone 0-1 with a 5.71 ERA in three starts in Arlington since leaving the Rangers.
However, he's allowed one run over 24 innings in his last three starts. He has won back-to-back outings, giving up one run in seven innings of a 5-2 victory over San Diego on Friday.
"That was his third (quality start) in a row, threw the ball the same way," manager Kirk Gibson said. "Just really good command of what he was doing, pretty efficient."
Only one hitter in the majors has faced McCarthy more than Texas' Adrian Beltre, who is 13 for 31 (.419) with two homers against him. McCarthy has fared better against Elvis Andrus (3 for 18) and Nelson Cruz (1 for 17).
Andrus is hitting .227 at home while Cruz is at .215.
Mitch Moreland has gone 6 for 15 with two homers against McCarthy and is batting .338 at home.
Like McCarthy, Justin Grimm (4-3, 4.05) has won his last two outings. Grimm yielded three runs and a season-high 10 hits over 6 1-3 innings in a 9-5 victory at Seattle on Friday.
The right-hander is 2-1 with a 2.79 ERA at home as he heads into his first start against the Diamondbacks.
Arizona (30-22) has won three straight entering a nine-game trip. The Diamondbacks are 14-10 on the road, but 4-10 all-time at Texas.
"We've been pretty good on the road," Gibson said. "These guys get along well, they prepare well and we've got a good routine."
Gerardo Parra, who left the second game Monday with a strained left calf, was in the lineup Wednesday before the game was rained out.
Willie Bloomquist is close to making his season debut for Arizona. The infielder has been rehabbing in the minors after starting 2013 on the disabled list with a strained right intercostal muscle.
Arizona's Martin Prado has nine hits in his last 16 at-bats, but he's a .200 hitter on the road compared to .311 at home.
Texas' Ian Kinsler (bruised ribs) was eligible to come off the disabled list Sunday before suffering a setback with what the team termed a stress reaction in that same area on his right side.
"We're probably looking at another couple of weeks," general manager Jon Daniels said.
