Quick facts about the battle between Tyler Duffey and Ricky Nolasco for the fifth spot in the Twins rotation:

2015:

Duffey was 5-1 with a 3.10 ERA in 10 starts for the twins after being called up from Class AAA Rochester. His first start at Toronto was a disaster but he was the Twins' most consistent starter by the end of the season.

Nolasco was 5-2 with a 6.75 ERA, missing most of the season with an ankle injury that ended a start in May against Toronto. He gave up eight earned runs in 4 2/3 innings in two appearances over the final days of the season.

Spring training:

Nolasco has pitched 13 1/3 innings in four games this spring with a 4.05 ERA. He has given up 14 hits and walked five while striking out 14. He has no allowed any home runs.

Duffey has a 6.83 ERA over 8 1/3 innings in three appearances. He has given up 10 hits and three walks while striking out four.

Contract:

Nolasco signed a four-year, $49 million contract that runs through 2017 with an option year in 2018. He can block a trade to three teams, which were Boston, the Yankees and Toronto as of December 15, according to Cot's Baseball Contracts.

Duffey is signed to a one-year contract, presumably for the major league minimum of $507,500.
