Thompson, rated as the Rangers' No. 4 prospect according to MLB.com's Prospect Watch, threw first-pitch strikes to 16 of the 22 batters he faced. He also joined big leaguer Jered Weaver (2003) as the only members of a U.S. Pan-Am team to throw six-plus innings while only allowing one hit.
With a total of 14 strikeouts in the game, Team USA tied its single-game team Pan-Am Games mark (against Canada in 1997 and Nicaragua in '91). The American club will play the Dominican Republic on Thursday.
