Lois Weldon Bowlin was a Major League Baseball third baseman. Nicknamed "Hoss", he was signed by the St. Louis Cardinals as an amateur free agent in 1959, and acquired by the Kansas City Athletics in August 1961. He started two games for the A's in 1967. Both games he appeared in were on the road against the California Angels at Anaheim Stadium. He had five at bats, because Sal Bando pinch-hit for him and replaced him at third in both games. Bowlin's one hit, a single to right, came against pitcher Jack Hamilton, who earlier in the season had hit Red Sox All-Star Tony Conigliaro in the face with a fastball. In his thirteen innings on the field, Bowlin recorded four assists and made no errors.
