Since the last stock report the Texas Rangers haven't lost, winning six straight in sweeps over the Houston Astros and San Diego Padres. So everyone's stock is mostly up. Here's a look:

STOCK UP

Yu Darvish: After struggling with his command against Oakland a few starts ago, Darvish was given extra time to work on his mechanics and, more important, rest. The 25-year-old has looked good in his last two starts, helping the Rangers get on this winning streak. His latest was an eight-inning gem against the San Diego Padres on Wednesday.

Justin Grimm: He was called up from Double-A Frisco to make his major league debut last Saturday and came through with a quality start. It was good enough to stay in the rotation for now with all the injuries. He'll start again Monday against Detroit.

Adrian Beltre: The third baseman is really hitting the ball right now. In the last six games, Beltre is 10-for-23 (.435) with two homers and seven RBIs. He's batting .313 on the season.

STOCK DOWN

Injuries: The bug just keeps biting the Rangers. The latest victim: Mitch Moreland. The first baseman strained his hamstring Tuesday and is expected to land on the disabled list. He joins a crowded injury list with Derek Holland, Neftali Feliz and Alexi Ogando.

Scott Feldman: He pitched well Tuesday, but his long-term stock has slowly dipped thanks to struggles and, frankly, poor luck with his defense behind him. Feldman, though he isn't happy about it, heads back to the bullpen now in his long-relief role.

Mike Napoli: The catcher is 1-for-15 since last week's stock report, playing in four of the club's last six games. Napoli is hitting .222 so far in June after batting .221 in May. It's worth pointing out that he started slowly the first few months last year and really turned it on starting July 4. We'll see if he can repeat that in 2012.
