Guerrero, who batted .319 with 173 homers and 616 RBIs in his time with the Angels, said he had no hard feelings about his former club and that he was excited to return to Anaheim.
"I'm very happy to be back," Guerrero said through a translator. "I saw some cousins of mine I hadn't seen in a long time and also being back after spending six years here is very special."
Guerrero, who was a fan favorite in Anaheim after winning the American League MVP Award in his first season with the team in 2004, said before Tuesday's series opener that he's hoping to get a positive response from the home crowd.
"I want to take a wait and see approach on that but I don't think did anything bad here so hopefully what I'll hear is applause," Guerrero said. "I don't want to build it up too much but I'm excited to see what happens."
Guerrero has been a force while with the Rangers, as he enters the three-game set batting .327 with 15 homers and 60 RBIs in 71 games. Texas manager Ron Washington said it's all because he's finally healthy after batting knee injuries last season that limited him to a career-low .295 batting average along with 15 homers and 50 RBIs.
"He did everything he could over the winter to get healthy, and so far we've kept him that way," Washington said. "I'm not surprised, and I don't think anyone in this part of the country is surprised because we've seen it before."
