He then went on to a second place in the Brabantse Pijl, winning the sprint of the group after nearly getting to lone escapee Ben Hermans. At the Amstel Gold Race, Matthews grabbed another notable result, when he came in third of the final dash for the line while being part of a small leading group.

Matthews was expected to contend for the points classification at the 2017 Tour de France, and his chances were boosted on Stage 4 after an incident during the final sprint which saw Mark Cavendish forced out of the race through injury and Peter Sagan, winner of the classification in the previous 5 Tours, disqualified. Matthews won Stage 14, a reduced peloton uphill sprint finish at Rodez. On Stage 16, the high pace set by Matthews' dropped the green jersey wearer Kittel; Matthews, who was second to Kittel in points classification, won the stage. On Stage 17, Kittel crashed and withdrew from the Tour, putting Matthews in the green jersey. Matthews retained the jersey to Paris.
