Former Oakland A's pitcher Brandon McCarthy signed with the Arizona Diamondbacks on Friday, which came as a surprise to some. McCarthy was a beloved figured in Oakland, and he's earned a reputation of being one of the nicer guys in baseball.

As news broke that he had signed with the D-backs, quite a few prominent baseball voices weighed in on the move over Twitter. Here were a few highlights from Friday afternoon.

Brandon's wife, Amanda McCarthy, has a large following on Twitter and took a chance to thank the fans. Here is what she tweeted out:

@athleticsnation thank you guys for taking me in with open arms. Best fans in baseball.

As for a couple of his teammates, fellow pitcher Brett Anderson offered some wise words to his wealthy former teammate.

Don't spend it all at one place @bmccarthy32 "@jcrasnick McCarthy's contract $2.5M signing bonus, salaries $4M and $9M for total of $15.5M."

Hey, I can think of a few things to buy with that much money.

Sean Doolittle of the A's had a request for his former teammate before he headed to the hot deserts of Arizona.

Finally, ESPN's national baseball writer, Jerry Crasnick, echoed what so many had already said to McCarthy. It appears he will fit in just fine with his new teammates in Phoenix.
