The Rays recalled Boyle from Triple-A Durham on Tuesday and will have him start the second game of the season Saturday against the Cardinals, Marc Topkin of the Tampa Bay Times reports.
The right-hander was competing for a roster spot before being sent to minor-league camp last week, but he'll end up being a late addition to the Opening Day rotation with Ryan Pepiot (hip) headed to the injured list Nick Martinez (knee) banged up. Boyle started in nine of his 13 appearances for Tampa Bay last season and had a 4.67 ERA, 1.37 WHIP and 58:28 K:BB across 52 innings.
