Angels starter Jason Vargas will undergo surgery to remove a blood clot this week, reports Mike DiGiovanna of the LA Times. Vargas was placed on the 15-day disabled list last week and will miss three to four weeks.
Vargas is 6-4 with a 3.65 ERA and 1.36 WHIP in 14 starts so far this season. He was named the American League's pitcher of the month in May. Right-hander Billy Buckner replaced Vargas on the roster. The team has used 10 different starting pitchers so far this season.
