Peter Lovrich (born October 16, 1942, at Blue Island, Illinois) is an American former Major League Baseball pitcher. He played for the Kansas City Athletics during the 1963 season.
Lovrich attended Arizona State University. The 6 ft 4 in (1.93 m), 200 lb (91 kg) right hander was the first former ASU Sun Devil player to reach Major League Baseball. Lovrich appeared in 20 games played for the 1963 Athletics, and gave up 25 hits and ten bases on balls, with 16 strikeouts, in 20⅔ innings pitched. He started one game, August 23 against the Detroit Tigers, and lasted only one-third of an inning, giving up four earned runs in an eventual 17–2 defeat. However, his one victory came in relief on July 15 against the eventual American League champion New York Yankees. He pitched a scoreless 12th inning, and bunted the winning run into scoring position during the bottom of the frame.
