ARLINGTON — The season started 10 days ago and the Texas Rangers’ top two starters are ailing from injuries. The setbacks haven’t been significant enough for either Matt Harrison or Yu Darvish to miss a start, but it’s certainly not good news.The Rangers revealed Monday evening that Harrison exited his last start with lower back stiffness and he had not participated in on-field drills on Sunday or Monday.Harrison is still scheduled to make his start Thursday at Seattle, but more will be known after he goes through a bullpen session Tuesday. Harrison, an 18-game winner last season, has gotten off to a slow start. He is 0-2 with an 8.44 ERA, allowing five runs on eight hits with four walks and three strikeouts over five innings in his last start against the Angels on Saturday.Darvish, meanwhile, continues to deal with a blister-like injury on his right ring finger. He exited after five innings Sunday, as skin came off an area of his finger similar to what happened to him in his season debut against the Astros on April 2.Darvish is expected to make his start Friday in Seattle, and manager Ron Washington doesn’t believe this will be a lingering issue.“He’s never had it before, so we’ll get rid of it at some point,” Washington said. “It’s not anything that I feel will be a hindrance every time he takes the ball.”Washington said Darvish would have liked to stay in the game Sunday, but said it’s too early in the season to risk further injury.Despite being pulled after the fifth inning, Darvish still got the win and improved to 6-0 with a 2.12 ERA in seven career starts in April. That’s the most April wins of any pitcher the past two seasons, and his 53 strikeouts are the most over that same time frame.Scheppers’ hot startThere’s never been a question about the potential Tanner Scheppers has of being a late-inning, power arm out of the bullpen. He’s shown that so far this season with 32/3 scoreless innings, retiring 11 of the 13 batters he’s faced.The question is whether Scheppers can deliver on a consistent basis.“That’s the name of the game,” Scheppers said. “It’s about going out there and doing it every single night. It’s a long year. I’ve got to stay focused and take it pitch by pitch. Everything else will take care of itself.”Ready for the majorsNick Tepesch realizes his dream Tuesday as he makes his major-league debut. The rookie right-hander believes he’s ready to take on the best hitters around, and so do the Rangers.“I feel like I’m ready as long as I stick with my routine and keep it as normal as possible,” Tepesch said. “You don’t want to try and do anything different. That’s the main thing.”Tepesch allowed an unearned run on five hits with no walks and five strikeouts over five innings in a start for Triple A Round Rock last Thursday. He combined to go 11-6 with a 3.67 ERA and 127 strikeouts in stints at High A Myrtle Beach and Double A Frisco last season.Manager Ron Washington has already talked with Tepesch about his debut.“The best thing we can do for him is to let him go out there and figure it out himself,” Washington said. “Not put too much on his mind, not think too much. Because he’s in a situation he knows nothing about.”Club gets catcherThe Rangers announced Monday that they acquired catcher Robinson Chirinos from the Rays in exchange for a player to be named later or cash considerations. Chirinos, who was designated for assignment by the Rays, was optioned to Triple A Round Rock.To clear a spot on the 40-man roster, left-hander Jeff Beliveau was designated for assignment. Beliveau, acquired on a waiver claim this off-season, was at Round Rock.
