Tampa Bay Devil Rays/Rays

Sonnanstine made his first major league start against the Toronto Blue Jays, receiving a no-decision. He picked up his first major league win on June 10, 2007, in a game against the Florida Marlins.

Sonnanstine demonstrated strikeout potential in 2007 when, through seven innings of work against the Marlins, he struck out ten batters, including a franchise-record seven in a row, while allowing two runs on seven hits. He also went 2-for-3 as a batter, scored his first run and drove in his first career run.

Sonnanstine has impressed many by his mental approach to the game, as he is a fierce competitor who takes a mental approach similar to that of Greg Maddux.^[1]

Andy Sonnanstine in the Minor Leagues

One of Sonnanstine's best starts came on August 31, 2007, against the New York Yankees at Yankee Stadium, where he pitched 8 innings, allowing 2 hits and no earned runs (1 unearned run) with 5 strikeouts and no walks. He ended his rookie campaign with a 6-10 record, pitching 1302⁄3 innings with an ERA of 5.85.

In another career night, on April 19, 2008, Sonnanstine pitched a complete game shutout against the Chicago White Sox. He allowed just 3 hits and struck out 4 batters while walking only one.^[2]

On October 6, 2008, Sonnanstine pitched 52⁄3 innings of 2-run baseball against the Chicago White Sox in Chicago. The Rays prevailed putting up six runs of their own and clinching the American League Division Series.

Sonnanstine allowed two stolen bases in two years ('07-'08).

On May 17, 2009, in a game against the Cleveland Indians, Sonnanstine was included in the starting lineup due to a mistake when Rays manager Joe Maddon entered the wrong lineup card, which had both Evan Longoria and Ben Zobrist playing third base, omitting the DH spot. The last time a pitcher was in the initial batting order in a game between two AL teams was September 23, 1976, when the White Sox batted Ken Brett eighth against the Twins.^[3] Sonnanstine went 1-for-3 with an RBI double and ended up winning the game despite the lineup error and giving up five runs.

Through July 1, 2009, Sonnanstine had the highest ERA of any major league pitcher (6.61). After the Rays traded Scott Kazmir to the Los Angeles Angels, Sonnanstine was recalled from Triple-A Durham to fill the hole in the starting rotation. In his first game since the beginning of the season against the rival Boston Red Sox, he posted a loss, giving up 3 earned runs, 2 home runs, 8 hits and 5 total runs in 4 innings with a pitch count of 91 (55s-36b).^[4]

On August 19, 2010, Sonnanstine was placed on the 15-day disabled list with a strained left hamstring. Jeremy Hellickson was called up to make his MLB debut that day against the Minnesota Twins.

Sonnastine's 2011 book with Tucker Elliot Tampa Bay Rays IQ: The Ultimate Test of True Fandom, published by Black Mesa books contains ten chapters of Rays history and offers up 200 trivia questions.
