ARLINGTON -- For the better part of three innings, Chicago left-hander Carlos Rodon was mowing through the Rangers' lineup.
But in the fourth inning he faltered, surrendering three two-out runs in the White Sox 13-4 loss to the Rangers Saturday night at Globe Life Park. He wasn't the only Chicago pitcher to struggle.
The White Sox bullpen combined to give up seven runs in 3 2/3 innings, effectively ending any chance the team had to get back in the game. Bruce Rondon was hit especially hard, giving up five runs, and recording only one out in what turned into a seven-run inning.
"You just don't like seeing a game like that," manager Rick Renteria said. "That wasn't a pretty game at all."
It was the third matchup in as many days that the bullpen has been called upon for an extended period. On Friday Renteria even turned to a position player -- outfielder Matt Davidson -- to get three outs to save the staff some work. 
"I wish we hadn't had to bring in [Jace] Fry to get out of that," Renteria said. "We wanted Brucey to finish that off. That didn't work. It just wasn't working today."

Rodon retired the first seven batters he faced -- three by strikeout. The only blemish in his first three innings came when Joey Gallo deposited a belt-high fastball into the bleachers in right-center field, cutting the White Sox early lead to 2-1.
The 25-year-old was within one strike of working a scoreless fourth inning, but lost his command. Rodon threw eight-straight balls to walk Rougned Odor and Jurickson Profar to load the bases.
Robinson Chirinos made him pay, lining Rodon's second pitch of the at-bat down the right-field line and up against the wall. Nomar Mazara scored. Odor scored. Profar scored.
In the blink of an eye the White Sox found themselves facing a 4-2 deficit.
"I left a fastball out over the middle," Rodon said. "We were trying to go in on him. I started off hot, but I just didn't give my team a chance to win today."

The White Sox jumped on Rangers starter Bartolo Colon in the first inning, with Yoan Moncada hitting the first pitch he saw back up the middle. Yolmer Sanchez followed that with a double that hugged the left-field line and put runners on second and third with no one out. But Chicago couldn't capitalize, as Moncada was thrown out at the plate on a grounder to short.
"I think that we should have scored a run early, which we didn't," Renteria said. "[In the second] we ended up scoring two, instead of three or more."
Missed opportunities cost the White Sox throughout the game. The team made two errors and left 10 runners in scoring position. In clutch situations, the White Sox bats were silent.
"It really costs you when you leave runners on base," Renteria said. "We just didn't end up executing as well as we want to."
After the game Renteria said he addressed his team about its play Saturday. He wants to see more out of them. He wants them to be sharper.
"All these young men are learning that big league baseball is not an easy thing," Renteria said. "One of the lessons that you learn is you really have to grind. Every pitch is important, everything you do matters. That's a lesson that they need to take to heart. Today's game was a hard lesson for them."
MOMENTS THAT MATTERED
The White Sox had two men on and one out in the top of the eighth inning, and were down by two runs. But Daniel Palka struck out swinging, and Moncada went down looking, ending the threat.

SOUND SMART
Colon labored through five innings to earn win number 245, which ties him with Dennis Martinez for the most career wins by a Latin-American pitcher.
Colon worked hard to earn the win. He threw 42 pitches in the second inning, but worked his way in and out of trouble to hold the White Sox to three runs over five-plus innings.
HE SAID IT
"If you're asking me if he gave the best effort that he possibly could, no he did not. He's a pretty good runner. I think he took it for granted that a play would be developing at the plate." -- Renteria, on Moncada being thrown out at the plate in the first inning
UP NEXT
The last time Reynaldo Lopez took the mound against the Rangers he allowed just two hits and struck out eight in eight scoreless innings on May 20. He'll need to replicate that success Sunday afternoon at 2:05 p.m. CT, as the White Sox face Rangers ace Cole Hamels in the series finale.
