Extra bases

• The Cubs traded outfielder Trevor Gretzky, son of hockey legend, Wayne Gretzky, to the Angels for Matthew Scioscia, who is manager Mike Scioscia's son. Matthew, 25, batted .194 at three Minor League levels last season, while Gretzky, 21, hit .274 at short-season Boise and Class A Kane County.

Angels general manager Jerry Dipoto told reporters the deal gives the two players a "new opportunity."

• Travis Wood, scheduled to follow Jeff Samardzija in the rotation, will tune up with a start in the Minor League camp on Friday, facing the D-backs' Triple-A team. Wood, 27, has given up seven runs on 14 hits and one walk over 10 2/3 innings, striking out 11.

• The Cubs assigned left-handed pitcher Tommy Hottovy to Minor League camp on Thursday, reducing the spring camp roster to 44. Hottovy, 32, had appeared in three spring games and given up one hit and one walk, while striking out five.

• The Cubs' wives will host a mystery baseball charity event on Saturday at Cubs Park to raise money for Paz de Cristo in Mesa, which helps feed, clothe and empower those in need in the east valley. Fans can purchase an autographed ball for $30. There also will be game-used bats, jerseys and other equipment for sale. The wives will be set up near the left-field gate inside Cubs Park.
