Both Robinson and Profar can play every position on the field except pitcher and catcher. If there is an advantage, Robinson gives the Rangers more speed off the bench for pinch-running.
"Profar needs to continue to play every day, that's the biggest thing," manager Jeff Banister said.
Robinson gives the Rangers a four-man bench, along with utility infielder Pete Kozma and backup catcher Robinson Chirinos. Joey Gallo was also on the bench for the second straight game with a sore left hamstring.
The Rangers are currently going with a seven-man bullpen with the All-Star break coming up on Monday. At some point shortly after the break, the Rangers will activate reliever Keone Kela off the disabled list. He is sidelined a sore right shoulder but is throwing off flat ground.
Yu Darvish said he is fine with the Rangers' request that he not pitch in the All-Star Game presented by Mastercard. Darvish originally said he would be willing to pitch in Tuesday's game even though he is starting on Sunday for the Rangers.
But the Rangers requested that he not pitch, citing his workload up to the point and potentially in the second half. Darvish agreed with the request.
"It is what it is," Darvish said. "I've seen others pitch [on Sunday] and then didn't pitch. When we decided I was going to pitch the last game before the All-Star break and we looked at the schedule … we decided maybe this is what we need to do."
Darvish will likely start the third game after the All-Star break on Sunday in Kansas City. Martin Perez is expected to pitch the first game on Friday, followed by Cole Hamels on Saturday.
• Pitcher Ernesto Frieri cleared outright waivers and has accepted his assignment to Round Rock. Because of his service time, Frieri had the right to refuse assignment and become a free agent.
• Reliever Tanner Scheppers was the starting pitcher for Round Rock on Saturday night. The Rangers are trying to get Scheppers multiple innings, but Banister said there have been no discussions of turning him into a starter. The Rangers did that in 2014 and Scheppers ended up on the DL with a sore right elbow.
• The Rangers had gone 51 games without a shutout before their 10-0 win vs. the Angels on Friday night. That was the longest such streak in the Major Leagues, 13 more than any other club.
