Alcaraz becomes second player to join Martinez from Wigan.
Everton have announced their second signing under new manager Roberto Martinez in Antolin Alcaraz and it is also the second player to arrive from the Spaniard’s former club Wigan.
The 30-year-old defender joins on a free transfer with the Paraguayan’s contract at the DW Stadium having expired this summer and signs a two-year deal with the Toffees.
Alcaraz becomes the second former Latics man to link-up with Martinez following the acquisition of Arouna Kone from the Lancashire club on Monday.
The 39-year-old boss brought the centre-back to England in 2010 from Club Brugge in Belgium, with the Paraguay international having also played for Fiorentina, Beira-Mar and Argentinian side Racing Club.
Alcaraz has also earned 24 caps for his country and scored two goals since making his debut in 2008 – playing every match on the run to the quarter-finals at the 2010 World Cup in South Africa.
During three years with Wigan the South American played 77 competitive games in all competitions, including the FA Cup final triumph against Manchester City in May this year.
The defender will now head to Goodison Park to join up with the Everton squad as the Merseyside club prepare for their first season without David Moyes since 2002.
Moyes left the Toffees to fill the managerial vacancy left by Sir Alex Ferguson at Manchester United and Martinez, despite being relegated with Wigan, was brought in as the Scot’s replacement.
Last season the club finished sixth in the table ahead of rivals Liverpool so the ex-Latics boss will have it all to do to emulate that feat.
