ANAHEIM -- Rangers closer Sam Dyson and pitching coach Doug Brocail were huddled over a video machine after a 6-5 loss to the Angels on Tuesday night. They were trying to figure out what's happening with the sinker that made Dyson one of the best relief pitchers in the American League.
"Same as last week, I'm working side to side instead of getting on top [of the ball] and over," Dyson said. "It's a small adjustment. I don't feel myself doing anything different. Hopefully I can make an adjustment before the next time."
The Rangers are hoping for that as well.
Dyson was asked to protect a 5-2 lead going into the ninth and instead allowed three runs for his second blown save of the season. Dyson has made four appearances and has allowed 11 runs on 11 hits and three walks over just three innings.
"It's tough, I've had my rear handed to me every time out," Dyson said. "It's attacking hitters more and making better pitches. There is no rhyme or reason, I've got to suck it up."
Dyson was not the only one having trouble Tuesday night. Tony Barnette gave up a run in the eighth on doubles by Michael Trout and Cameron Maybin, and Jeremy Jeffress couldn't keep it tied in the tenth. A leadoff walk cost him and the Angels ended up winning on Carlos Perez's squeeze bunt. Matt Bush was unavailable after throwing 29 pitches on Sunday.
But Dyson is easily the biggest concern because he fills the most vital role.
"We've been evaluating it from day one and considering all our options," manager Jeff Banister said. "We can't continue to lose ballgames in this manner. We'll look at all our options and see which way we go. Sam is searching to find it. We feel when Sam has good tempo and rhythm and sinking life, he's a quality pitcher for us out of the back end."
Dyson's inning started with Danny Espinosa leading off with a home run to left-center. Ben Revere struck out, but Yunel Escobar grounded a double down the third baseline to make it a two-run game. Kole Calhoun flied out, leaving Dyson one out away from a save.
That one out was Trout. Dyson got ahead, 1-2, and just missed with a sinker off the outside corner.
"I thought it was a strike," Dyson said. "I made a better pitch on the next pitch."
Trout lined that one down the right-field line for a double, bringing up Jose Pujols. Banister had Dyson pitch to Pujols with first base open because he represented the winning run. Pujols singled to left to tie the game. Dyson retired Andrelton Simmons on a fly to center to end the inning, but that only delayed the ending to the 10th.
The blown save cost starter Cole Hamels the victory after he held the Angels to one run in seven innings.

"Dyson's great, he's tremendous," Hamels said. "He's going to be back and solidify the ninth inning. He's a warrior. I have all the faith in him. He can close every game of mine."
