In May, Rodriguez reached the final of the PDC World Youth Championship where he lost 6–4 to Keegan Brown at the O2 Arena in London as part of the Premier League finals night. Reaching the final secured him a place in the 2014 Grand Slam of Darts. Rodriguez was now Austria's number two player behind Mensur Suljović and they teamed up at the World Cup of Darts, but lost both their singles matches in the second round against the Belgium brothers of Kim and Ronny Huybrechts. Rodriguez reached the quarter-finals of a Pro Tour event for the first time at the 14th Players Championship defeating the likes of Gary Anderson, Paul Nicholson and Jamie Caven, before losing 6–1 to Ian White. His play throughout the year earned him a debut in the European Championship where he lost 6–2 to Robert Thornton in the opening round. At the Grand Slam, Rodriguez beat world number three Adrian Lewis 5–2 in his opening group game before losing 5–1 to Dave Chisnall. He went into his final group game knowing a win over Brown would see him qualify for the last 16 and, despite coming back from 3–0 down to level at 3–3, he lost 5–3.
