Jayson Werth has the third-highest average in the National League (.327) and has produced well for the Washington Nationals this season.
Werth is hitting .327/.399/.546 with 23 home runs and 71 RBIs. He ranks first in the NL in slugging and OPS.
The Nationals signed Werth to an eye-popping seven-year, $126 million contract in December 2010 and the club remains pleased with the deal.
"We were always positive about Jayson," principal owner Mark Lerner said. "What people don't realize about Jayson is, it's not only what he does on the field, it's what he does in the clubhouse. He is a real leader, a true professional. We are glad he is a member of the Nationals.
"He helped bring the culture of winning that we now have. Even when he is on the disabled list, he is always there, encouraging the guys, doing the things he needs to do as a leader. That is so important."
