ARLINGTON, Texas -- Some of you have emailed and hit me up on Twitter concerned about starting Justin Grimm's major league service time clock by bringing him up Saturday.

A quick explanation: The Rangers could leave Grimm in the minors for two more seasons before that clock would have to get started, thereby delaying when he might become arbitration-eligible and then a free agent.

But the same thing was said by some in spring training in regard to 21-year-old Robbie Ross. And it's clear Ross was ready for the big leagues, so if the club believes Grimm is ready, start the clock. This is not the 2007 Rangers. This club is trying to win a World Series. And if Grimm helps them win a game or two in their quest to do that, they'll happily deal with the consequences of promoting him a bit early.

Other thoughts on the Grimm move:

* Obviously, I'm in favor of this. I blogged about it Wednesday morning, explaining why I thought he'd be a good candidate. Is it a risk? Yes. But this team takes calculated risks. He's got a mature head on his shoulders and has put up solid numbers this season. The options in Triple-A weren't great. Why not give Grimm a chance?

* The manager made it clear that Robbie Ross wasn't a candidate for the Saturday start because of his value in the bullpen. Ron Washington reiterated that again Thursday.

"He's too important to me in my bullpen to put him out there and put him in the starting rotation," Washington said. "I don't care how good your starting pitching is, you need a bullpen. You can't field a successful team out there without a bullpen. Don't have one and see where you end up."

* Roy Oswalt pitches Sunday. Depending on how that goes, the club will talk about a plan for the future, but it's possible Oswalt could need another start. When he returns, there's no guarantee that he simply slides in for Grimm. What if Grimm pitches well on Saturday? Maybe Oswalt ends up in Scott Feldman's spot. We'll see. Oswalt threw a bullpen session in Arlington on Thursday, and Washington said Oswalt knows he has to pitch better and show he can get deeper into games.

* Grimm's biggest attribute: He has had consistently good command. He has 67 strikeouts and only 14 walks in 13 starts (77 innings). He doesn't hurt himself much and that will be his goal Saturday. Remember, he'll be pitching in front of a sellout crowd in Arlington. The Rangers believe Grimm has the belief and confidence in himself that he can do that and still pitch well.

* The scout that got Grimm signed in 2010 (fifth round), Ryan Coe, is being flown in by the club for the right-hander's major league debut. That's a nice thing the club does as a reminder of how important those scouts are to evaluating talent that is capable of getting to the big leagues.
