How many starters does a MLB team really use?

Twins beat-writer Phil Miller wrote in past Sunday’s edition of the Minneapolis Star Tribune that the Minnesota Twins could have as many as 12 different pitchers fighting for the five spots in the Twins 2017 starting rotation. Keep that number 12 in the back of your mind as you read this. Here are the pitchers Miller listed as possible starters in 2017.

TWINS STARTING ROTATION CANDIDATES

Ervin Santana (R), 34: 7-11 last season, but his 3.38 ERA was 10th-best in the American League.

Phil Hughes (R), 30: Missed most of last season because of thoracic outlet syndrome. Gave up league-high 29 home runs in 2015.

Kyle Gibson (R), 29: Fourth year in rotation (98 starts), but ERA rocketed to 5.07 in 2016.

Hector Santiago (L), 29: Acquired from Angels last season. Another starter who gives up lots of home runs.

Jose Berrios (R), 22: Team’s top young pitching prospect has been bombed in majors (8.02 ERA).

Tyler Duffey (R), 26: In 26 starts last season his 6.43 ERA was worst among pitchers with more than 130 innings.

Trevor May (R), 27: Back injury hampered him last season, when he was a reliever. He wants to start.

Adalberto Mejia (R), 23: Picked up from Giants in Eduardo Nunez trade last season. In 566 minor league innings he has 487 K’s.

Nick Tepesch (R), 28: Had 39 starts for Texas in 2013-14. He missed 2015 because of shoulder issues; he’s on a minor league deal.

Ryan Vogelsong (R), 39: Grizzled veteran has 179 starts in 12 seasons; 3-7, 4.81 ERA for Giants last year.

Justin Haley (R), 25: Proven starter in Class AAA was picked up in the Rule 5 draft, meaning he’s likely to make the team.

Stephen Gonsalves (L), 22: Twins minor league pitcher of the year in 2016; was dominant at Class AA Chattanooga.

It would be nice to have quality over quantity but one has to play with the cards they are dealt or the starters they might have. In 2016 the American League teams used 157 different starters an average of 10.47 starters per team. The Toronto Blue Jays used only seven starters in 2016 while the Los Angeles Angels of Anaheim sent 15 different starters to the mound. The Twins marched out 11 different pitchers to start their games in 2016.

The National League teams used 176 different starters in their quest for wins and that comes out to an average of 11.73 starters. The St. Louis Cardinals and San Francisco Giants only required eight starters each while the Atlanta Braves had double that, they needed 16 starters to get through the season. 

The Twins have used as many as 13 different starters in 1962 and 1995 and as few as six starters in 1972 but they only played 154 games that year. If you look at the Twins average number of starters used over the years per season you end up with 9.68 so even though the battle for the starting rotation will take place this spring and there will probably be five winners by Opening Day, there is no assurance they will be starting games at Target Field come September. Starting pitchers will be lost due to injury, performance, trades, and personal reasons so the more pitchers the Twins have ready to start big league games the better. The message to the pitchers who won’t be Twins starters on Opening Day is to hang in there because your turn is coming, be ready.
