In late 2010 Naylor played the second half of the season in the Australian Baseball League, making his debut on 22 December 2010 in Melbourne where he gave up a two-run home run in two innings of relief at the batter-friendly Melbourne Showgrounds. He finished the season with a 3.21 ERA over 14 innings including two starts. In 2011, he started a Phillies spring training game against Florida State University, picking up the win in a scoreless outing.[2]
He missed the entire 2011 season after undergoing Tommy John surgery, and was designated for assignment by the Phillies on 16 September 2011.[3] He was then released from the Phillies as a free agent in November 2012.
Brisbane Bandits
In 2014, Naylor returned to Brisbane Bandits and pitched in three games, with 13 strikeouts in 13.2 innings earning a 7.24 ERA. He finished his tenure in the ABL with a 0–2 record.[4]
Naylor made his debut in Japan in an inter-league match against Ishikawa Million Stars where he threw 6 innings allowing only 3 hits and 0 runs.[6]
He was largely used as starting pitcher for the remainder of his tenure and recorded 4 wins, 1 loss, and 2 saves with an ERA of 1.37 and 55 strikeouts.[7]
In his second start for the Dragons, Naylor threw 8 innings to register his first win as well as contributing with the bat by hitting a solo homer in the bottom of the 4th inning against the Yakult Swallows.[10]
After starting his second year with the Dragons in the starting rotation, his season was interrupted by elbow soreness when pitching against the Yomiuri Giants on 6 May 2016 ruling him out for an unspecified amount of time.[11] He attempted to get back to fitness with the Dragons Western League team but ultimately to no avail as a niggling shoulder issue ruled him out of the season.[12] Naylor remained in Nagoya to undergo treatment with a view to staying with the Dragons through the 2017 season to help in the lead-up to the 2017 World Baseball Classic in March where he would be expected to represent Australia at the tournament.[12]
Following his release from the Dragons, Naylor teamed up once more with his hometown team the Brisbane Bandits in December 2016.[16] He re-signed with the team for the 2018/19 season.
