Wilson, a two-time All-Star with Texas, ranks ninth in the American League in strikeouts (93) and is fifth in opponent's batting average (.217). Richards ranks higher than Wilson in both categories. Wilson is in the top 20 in the American League in both WAR (wins above replacement) and RAR (runs better than replacement).
Wilson's numbers this season are comparable to his 2011 numbers, when he made his first All-Star Game. In 2011, the southpaw had a 3.20 ERA and 117 strikeouts by the All-Star break while batters were hitting .241 off him.
Pitchers will be determined through a combination of player ballot and American League manager John Farrell's picks. Rosters will be unveiled on July 6.
