It's Friday, and that means our weekly look at the Rangers stock market. Certainly, in the past two days the offense has trended upward. But what else is headed up and which player or position stocks dropped a bit the last week? Let's take a look:

STOCK UP

Ian Kinsler: The leadoff hitter is the sparkplug of this offense. Sure, Josh Hamilton seems to get all the attention. But when this offense is clicking, it's usually doing so with Kinsler all over the bases and the box score. He was 3-for-5 last night and put pressure on the Angels all night. In the last week, Kinsler is batting .290, but through two games in August, he's 6-for-11 with two homers and four RBIs.

Mike Olt: His stock was so high that the Rangers did not want to trade him at the deadline, preferring to hang onto a prospect they believe has real potential to help them as early as this season. And they showed how they felt about him soon after the deadline passed, calling him up Wednesday night. Olt was 1-for-3 in his debut.

STOCK DOWN

Starting pitching: It certianly speaks to how well the offense did in the last two nights that the Rangers could have a 12.05 ERA from their starters in the four-game series with the Angels and earn a split. Even newest Ranger Ryan Dempster wasn't immune to the issues on the mound, as he gave up eight runs and couldn't get through five innings in his Texas debut on Thursday. ... Roy Oswalt's performance through six starts pushed him to the bullpen with the arrival of Dempster.

Yu Darvish: The 25-year-old Japanese pitcher struggled in his two starts in the last week. He was 1-1 with a 9.53 ERA with 13 strikeouts and nine walks. Opponents hit .261 against him and his batting average against on balls in play was .313. He'll look to improve in Boston next week.
